e2fsck命令功能的描述
e2fsck（extended file system check）命令是Linux 系统中用于对ext2、ext3、ext4 文件系统进行检查和修复的工具。
它的作用类似于Windows 系统的chkdsk 命令。
e2fsck 命令可以检查文件系统中的逻辑错误、物理错误、超级块和目录结构等问题，并对其进行修复。
在文件系统发生故障、出现错误或系统异常关闭后，通过运行e2fsck 命令可以使文件系统保持一致性和完整性，避免数据损坏和文件丢失。
e2fsck 命令的常用选项包括：
- -f：强制检查文件系统，即使文件系统没有标记为“不需要检查”。
- -v：输出更详细的检查过程信息，包括检测到的错误和修复的过程。
- -y：自动回答“是”来所有问题，如“你想修复这个文件吗？”。
这可以用于无人值守检测和修复文件系统。
例如，如果要对/dev/sda1 分区上的ext4 文件系统进行检查和修复，可以使用以下命令：
```
e2fsck -f -v /dev/sda1
```
这将对/dev/sda1 分区上的ext4 文件系统进行强制检查并输出详细的检查和修复过程。
如果发现错误，e2fsck 将尝试修复它们。
需要注意的是，在运行e2fsck 命令时，应确保该文件系统没有被挂载，否则可能会导致数据损坏和文件丢失。
因此，最好在单用户模式下运行该命令。

语法：fsck [-aANPrRsTV][-t ][文件系统...]补充说明：当文件系统发生错误时，可用fsck指令尝试加以修复。
参数：-a 自动修复文件系统，不询问任何问题。
-A 依照/etc/fstab配置文件的内容，检查文件内所列的全部文件系统。
文件/etc/fstab存放的是系统中的文件系统信息。
当正确的设置了该文件，则可以通过"mount /directoryname"命令来加载一个文件系统，每种文件系统都对应一个独立的行，每行中的字段都有空格或tab键分开。
同时fsck、mount、umount的等命令都利用该程序。
-N 不执行指令，仅列出实际执行会进行的动作。
-P 当搭配"-A"参数使用时，则会同时检查所有的文件系统。
-r 采用互动模式，在执行修复时询问问题，让用户得以确认并决定处理方式。
-R 当搭配"-A"参数使用时，则会略过/目录的文件系统不予检查。
-s 依序执行检查作业，而非同时执行。
-t 指定要检查的文件系统类型。
-T 执行fsck指令时，不显示标题信息。
-V 显示指令执行过程。

linux fsck命令参数及用法详解---检查修复linux文件系统命令fsck命令：fsck使用权限: 超级使用者使用方式: fsck [-sACVRP] [-t fstype] [--] [fsck-options] file sys [...]说明：在Linux系统中，为了增加系统性能，通常系统默认一些数据写在内存中，并不会直接将数据写入硬盘，这是因为内存速度要比硬盘快若干倍。
但是有个问题，万一由于“断电”或者其他未知原因，造成系统死机，怎么办？系统就崩溃了。
所以，我们需要在特定的时候让数据直接回存到硬盘中。
这里提供几个常用的命令，其中，fsck命令最重要. 当文件系统发生错误时，可用fsck命令尝试加以修复.直接采用分区编号(如/dev/had3),或使用挂载点(Mount Point,如/、/usr等)指定文件系统皆可。
假设一次指定多个文件系统，而这些系统分别位于不同的物理磁盘上，则fsck将会尝试同步的方式去检查他们，以节省操作时间。
参数：filesys ：device 名称(eg./dev/sda1)，mount 点(eg. / 或/usr)-t : 给定档案系统的型式，若在/etc/fstab 中已有定义或kernel 本身已支援的则不需加上此参数-s : 依序一个一个地执行fsck 的指令来检查-A : 对/etc/fstab 中所有列出来的partition 做检查-C : 显示完整的检查进度-d : 列印e2fsck的debug 结果-p : 同时有-A 条件时，同时有多个fsck 的检查一起执行-R : 同时有-A 条件时，省略/ 不检查-V : 详细显示模式-a : 如果检查有错则自动修复-r : 如果检查有错则由使用者回答是否修复补充说明：例子:检查msdos 档案系统的/dev/hda5 是否正常，如果有异常便自动修复:fsck -t msdos -a /dev/hda5注意:此指令可与/etc/fstab 相互参考操作来加以了解。
CC110x CC111x OOK ASK Register Settings说明书
CC110x/CC111x OOK/ASK Register SettingsBy Sverre HellanKeywordsOOKASKPER (Packet Error Rate)CC1100CC1100ECC1101CC1110CC1111CC4301 IntroductionThis design note provides guidelines forfinding optimum register settings forOOK/ASK operation. The starting point forthe optimization is the preferred settingsgiven by the SmartRF®Studio SW. Theuser needs to measure the sensitivity(PER) over the full input dynamic range todetermine the optimum settings.This design note uses CC1101 as anexample on how to find optimum registersettings, but it is also applicable forCC1100, CC1100E, CC1110, CC1111,and CC430.Table of ContentsKEYWORDS (1)1INTRODUCTION (1)2ABBREVIATIONS (2)3OOK/ASK REGISTER SETTINGS (3)3.1AGC S ETTINGS (3)3.2IF F REQUENCY (4)3.3P ROCEDURE FOR F INDING OOK/ASK S ETTINGS USING S MART RF®S TUDIO (5)4GENERAL INFORMATION (8)4.1D OCUMENT H ISTORY (8)2 AbbreviationsAGC Automatic Gain ControlASK Amplitude Shift KeyingEM Evaluation Module2-FSK Frequency Shift KeyingGFSK Gaussian shaped Frequency Shift KeyingIF Intermediate FrequencyMSK Minimum Shift KeyingOOK On-Off KeyingPER Packet Error RateSW Software3 OOK/ASK Register Settings3.1 AGC SettingsThe register settings provided by SmartRF®Studio have been optimized for 2-FSK/GFSK/MSK modulation and when using one of the preferred settings and only changing the modulation format to OOK/ASK, the AGC settings might result in unstable or non-optimum reception (i.e. degraded sensitivity). This is pictured in Figure 1.Figure 1. Example of Unstable, Non-Optimum, and Optimum ReceptionThe optimum AGC settings change with RX filter bandwidth and data rate, but for OOK/ASK the following has been found to give good results:AGCCTRL2 = 0x03 to 0x07AGCCTRL1 = 0x00AGCCTRL0 = 0x91 or 0x92In the example shown in Figure 2, the best sensitivity is achieved with AGCCTRL2 = 0x04, AGCCTRL1 = 0x00, and AGCCTRL0 = 0x92. Please note that optimum register settings change with data rate so it is important to measure sensitivity for different combinations of AGCCTRL2 and AGCCTRL0. Furthermore, as shown in Figure 1, some combinations of AGC settings results in unstable reception. That is, for some input power levels above the sensitivity limit there will be degraded packet error rate (PER). It is therefore important to check the PER for the entire dynamic range and not only at the sensitivity limit. One option is to check the PER for every 2 dB increase in input power level.AGCCTRL2.MAGN_TARGET[2:0] is used to set an on-chip target value for the peak signal amplitude. MAGN_TARGET is used by the AGC loop to set the correct gain.AGCCTRL0.FILTER_LENGTH[1:0] is used to configure the ASK decision boundary. If the ASK decision boundary is set to 8 dB, the “low” bit must be at least 16 dB below the “high” bit.Figure 2. PER versus Input Power Level for Different AGC Register Settings (3.8 kBaud,100 kHz RX Filter Bandwidth) 3.2IF FrequencyRegister FSCTRL1 sets the IF frequency and the optimum value is different for different RX filter bandwidths. It is therefore recommended to find the FSCTRL1 setting using one of thepreferred RX filter bandwidth settings in SmartRF ®Studio (see Figure 3). If the wanted RX filter bandwidth is not given by one of the preferred settings, choose the FSCTRL1 setting for the first RX filter bandwidth that is wider than the wanted RX filter bandwidth.As an example, for a wanted 150 kHz RX filter bandwidth use the FSCTRL1 setting given for 232 kHz RX filter bandwidth.RX filter bandwidthsused by preferred settings:58 kHz, 100 kHz, 232 kHz, 325 kHz, 540 kHz, 812 kHzFigure 3. Available RX Filter Bandwidths Given by the Preferred Settings in SmartRF ®StudioNote that the FREND1, FIFOTHR, TEST2, and TEST1 register settings change for different RX filter bandwidths.FREND1:RX filter bandwidth > 101 kHz, FREND1 = 0xB6RX filter bandwidth ≤ 101 kHz, FREND1 = 0x56TEST2:RX filter bandwidth > 325 kHz, TEST2 = 0x88RX filter bandwidth ≤ 325 kHz, TEST2 = 0x81TEST1:RX filter bandwidth > 325 kHz, TEST1 = 0x31RX filter bandwidth ≤ 325 kHz, TEST1 = 0x35FIFOTHR:RX filter bandwidth > 325 kHz, FIFOTHR = 0x07RX filter bandwidth ≤ 325 kHz, FIFOTHR = 0x473.3 Procedure for Finding OOK/ASK Settings using SmartRF® StudioAs an example, assume 4.8 kBaud data rate and 203 kHz RX filter bandwidth.1) Use SmartRF®Studio to find the optimum IF frequency. Select the preferred setting that has an RX filter bandwidth equal to the wanted bandwidth. If the wanted RX filter bandwidth is not given by one of the preferred settings, chose the first RX filter bandwidth that is wider than the wanted bandwidth. For a 203 kHz wanted RX filter bandwidth, select the 232 kHz RX filter bandwidth for optimum IF frequency.2) Change the data rate and the RX filter bandwidth to the wanted values. Change the modulation format to ASK/OOK. Press “Reset CC1101 and write settings” (if SmartRF® Studio is being used to control a CC1101EM) and then “Copy settings to Register View”3) In Register View, change the AGCCTRL2, AGCCTRL1, and AGCCTRL0 settings as explained in Section 3.1. Make sure the FSCTRL1, FIFOTHR, FREND1, TEST2, and TEST1 registers are set as explained in Section 3.2. It is possible to print the register settings to a file using “Export CC1101 Registers” under “File”.Press the “Write” butt on for the register to be updated if SmartRF® Studio is being used to control a CC1101EM.4) If SmartRF ®Studio is being used to perform the test, go back to Normal View. Check the Manual Init box for the changes done in Register View to take effect.4 General Information4.1Document HistoryIMPORTANT NOTICETexas Instruments Incorporated and its subsidiaries(TI)reserve the right to make corrections,modifications,enhancements,improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete.All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty.Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty.Except where mandated by government requirements,testing of all parameters of each product is not necessarily performed.TI assumes no liability for applications assistance or customer product design.Customers are responsible for their products and applications using TI components.To minimize the risks associated with customer products and applications,customers should provide adequate design and operating safeguards.TI does not warrant or represent that any license,either express or implied,is granted under any TI patent right,copyright,mask work right, or other TI intellectual property right relating to any combination,machine,or process in which TI products or services are rmation published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement e of such information may require a license from a third party under the patents or other intellectual property of the third party,or a license from TI under the patents or other intellectual property of TI.Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties,conditions,limitations,and notices.Reproduction of this information with alteration is an unfair and deceptive business practice.TI is not responsible or liable for such altered rmation of third parties may be subject to additional restrictions.Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice.TI is not responsible or liable for any such statements.TI products are not authorized for use in safety-critical applications(such as life support)where a failure of the TI product would reasonably be expected to cause severe personal injury or death,unless officers of the parties have executed an agreement specifically governing such use.Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications,and acknowledge and agree that they are solely responsible for all legal,regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications,notwithstanding any applications-related information or support that may be provided by TI.Further,Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications.TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or"enhanced plastic."Only products designated by TI as military-grade meet military specifications.Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk,and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

fsck failed with error code
fsck failed with error code“fsck failed with error code” 是一个常见的错误消息，通常出现在Linux操作系统中。
fsck是文件系统一致性检查的缩写，它用于检查和修复文件系统中的错误。
当fsck失败并返回错误代码时，通常表示文件系统存在问题，需要进行修复。
出现这个错误的原因可能有很多，比如文件系统损坏、磁盘问题、系统配置不当等。
为了解决这个问题，你可以尝试以下方法：1. 检查磁盘错误：运行fsck命令时，可以加上“-f”参数来强制检查文件系统的一致性。
如果fsck发现错误，它会尝试修复它们。
例如：```sudo fsck -f /dev/sdx1```其中，“/dev/sdx1”是你的文件系统所在的分区。
2. 检查文件系统一致性：如果你不确定文件系统是否有问题，可以运行fsck命令进行检查。
如果没有问题，fsck会告诉你一切正常。
如果有问题，它会尝试修复它们。
例如：```sudo fsck /dev/sdx1```3. 检查磁盘健康状况：有时候磁盘本身可能存在问题，导致文件系统损坏。
你可以使用工具如smartmontools来检查磁盘的健康状况。
如果发现磁盘存在问题，可能需要更换磁盘。
4. 检查系统日志：查看系统日志文件（如/var/log/messages或/var/log/syslog）可能会提供更多关于fsck失败的错误信息。
你可以使用以下命令查看日志文件：```bashsudo cat /var/log/messages | grep fsck```或者```bashsudo cat /var/log/syslog | grep fsck```5. 寻求专业帮助：如果你无法解决这个问题，可能需要寻求专业人士的帮助。
他们可以提供更详细的诊断和修复方案。
fsck_msdos分析
最近准备重写android/external中自带的fsck工具，因为这个工具对于内存的占用太厉害了，在一些极端的大容量小簇的情况下会导致系统奔溃，所以准备重写一个。
Android自带的fsck在检查的时候会为每一个簇分配一个struct fatentry结构体，在后面的检查中构成簇链（cluster chain）。
这种方法虽然内存占用比较多，但是处理比较快速，而且适应性较强，可以处理任何情况，也算是一方面的优点吧。
（1）fat表的检查Fsck基本分为下面四个阶段：1.读FAT，并进行fat表的对比（为了保证fat表的完整性，会保持多份fat表）2.处理cluster chain。
对于错误情况进行交互式的处理。
3.处理文件目录项和文件4.处理一些无主（没有相应目录项）的数据，写入到LOST.DIR中5.写入fat表我本来不想罗列代码，但是对于一个码农来说，无代码的泛泛而论都显得十分空洞。
我是一懒的人，就用下面的表格来代表图。
在此不再赘述。
for (cl = CLUST_FIRST; cl < boot->NumClusters;)switch (boot->ClustMask) {case CLUST32_MASK:fat[cl].next = p[0] + (p[1] << 8)+ (p[2] << 16) + (p[3] << 24);fat[cl].next &= boot->ClustMask;ret |= checkclnum(boot, no, cl, &fat[cl].next);cl++;p += 4;break;case CLUST16_MASK:fat[cl].next = p[0] + (p[1] << 8);ret |= checkclnum(boot, no, cl, &fat[cl].next);cl++;p += 2;break;default:fat[cl].next = (p[0] + (p[1] << 8)) & 0x0fff;ret |= checkclnum(boot, no, cl, &fat[cl].next);cl++;if (cl >= boot->NumClusters)break;fat[cl].next = ((p[1] >> 4) + (p[2] << 4)) & 0x0fff;ret |= checkclnum(boot, no, cl, &fat[cl].next);cl++;p += 3;break;}上面的代码摘自external/fsck_msdos/fat.c文件。

fsck基本过程
fsck基本过程
`fsck`的基本过程如下：
1. 准备工作：在运行`fsck`之前，首先确保文件系统处于不挂载（unmounted）状态，以免造成数据损坏。
通常，需要在单用户模式下启动系统或使用一个启动光盘/USB驱动器来运行`fsck`，以确保没有正在访问文件系统的进程。
2. 运行`fsck`：使用命令来运行`fsck`，并指定要检查的文件系统设备。
例如，要检查一个`ext4`文件系统，可以使用以下命令：`fsck -t ext4 /dev/sda`。
3. 检查过程：`fsck`会对文件系统进行检查，查找并报告发现的问题。
它可能会执行以下操作：
- 修复索引节点（inode）问题。
- 扫描和修复坏块或损坏的数据块。
- 修复文件系统结构。
- 修复超级块中的错误。
4. 用户干预：在检查过程中，`fsck`可能会遇到需要用户决策的问题。
例如，可能会发现多个副本的坏块，并要求用户选择哪一个副本应该保留。
用户需要根据具体情况进行选择。
5. 修复完成：一旦`fsck`完成了检查和可能的修复工作，它会生成一个报告，指出修复了哪些问题，如果有的话。
6. 重新挂载：如果`fsck`未发现无法修复的严重问题，你可以尝试重新挂载文件系统，使其再次可用。
例如，可以使用以下命令挂载
磁盘：`mount -a`或者使用`reboot`命令重新启动系统。
c++ cli11命令行解析案例
C++ CLI11命令行解析案例1. 前言C++是一种非常流行的编程语言，被广泛应用于系统软件、游戏开发等领域。
在实际的开发工作中，经常需要用到命令行解析工具来帮助我们处理用户输入的参数。
CLI11是一个易于集成的C++命令行解析库，能够帮助我们快速构建命令行应用程序。
本文将介绍如何使用CLI11来处理命令行参数，并结合一个简单的示例来展示其用法。
2. CLI11的基本用法CLI11是一个开源的C++命令行解析库，使用它可以轻松地解析和处理命令行参数。
下面是一个简单的示例，演示了CLI11的基本用法：```c++#include "CLI/CLI.hpp"int m本人n(int argc, char* argv[]) {CLI::App app{"MyApp description"};std::string name;app.add_option("-n,--name", name, "User's name")->required();int age;app.add_option("-a,--age", age, "User's age");CLI11_PARSE(app, argc, argv);std::cout << "Hello, " << name << "! You are " << age << " years old." << std::endl;return 0;}```在这个示例中，我们首先包含了CLI11库的头文件，然后创建了一个App对象。
接着我们定义了两个命令行参数，分别是用户的名字和芳龄。
通过调用add_option方法，我们将这些参数添加到了App对象中。

rescue救援模式修复文件系统方法
r e s c u e救援模式修复文件系统方法(共5页)--本页仅作为文档封面，使用时请直接删除即可----内页可以根据需求调整合适字体及大小--rescue救援模式修复文件系统方法1、当发生意外断电时，系统启动不了，需要自己查看下，当时停止的界面，如果是根分区或其他分区检测失败导致无法正常启动系统，需要记录下出问题的分区，如/dev/VolGroup00/LogVol00 等。
2、将系统对应的安装光盘，放入光驱中，重启服务器，在出现下面图像时，输入 linux rescue 回车，这条命令是进入救援模式下。
如果需要将重要数据备份到其他移动设备中，如U盘或移动硬盘等，则需要在输入 linux rescue 前，插入移动设备，再输入 linux rescue 回车。
否则，等进入救援模式后，再插入移动设备的话，会因为没有加载相应驱动，导致无法识别移动设备。
3、选择语言，默认为English，直接回车即可；4、键盘选择，默认为us，直接回车即可；5、网络设置，如果不需要网络，可以选择NO；6、选择Continue，以可读写的模式挂载根分区，(Read-Only是以只读方式挂载根分区，Skip是跳过，不挂载根分区)7、直接回车；8、获得一个shell环境，执行 chroot /mnt/sysimage 回车，将根分区挂载到/mnt/sysimage 下面；9、如果想要挂载U盘，可以进行下面操作，例如将U盘/dev/sdb1挂载到/tmp 目录下的usb空目录上：(1)cd /tmp 进入/tmp 目录下；(2)mkdir usb 新建一个名为usb的空目录；(3)fdisk -l 查看U盘的设备名，例如/dev/sdb1；(4)mount /dev/sdb1 /tmp/usb 挂载U盘，U盘最好是FAT32格式；(5)可以将数据拷贝到/tmp/usb 目录下；(6)cd /home/db2inst1/archivelogs/db2inst1/ (要将日志文件打包)；(7)tar –zcvf ORCL (根据实际情况压缩打包,三个数据库全部打包)；cp /tmp/usbdf -h 可以查看所有被挂载上的磁盘使用情况；(8)umount /tmp/usb 使用完毕后，需要手动将U盘卸载掉。
