linux strace

strace is a command-line tool in Linux used to trace and debug system calls made by a program. It allows you to monitor the interactions between processes and the Linux kernel. By tracing system calls, you can gain insights into the behavior of a program, identify errors, and understand its resource usage.

To use strace, you simply need to run it followed by the command or program you want to trace. For example:

strace ls -l

This command will trace the system calls made by the 'ls -l' command.

Strace provides detailed information about each system call, such as the arguments passed, return values, and any errors encountered. It can be useful for troubleshooting issues related to file access, networking, process management, and more.

Keep in mind that strace produces a lot of output, so it is often helpful to redirect the output to a file for further analysis. You can do this by using the '>' symbol followed by the filename:

strace ls -l > output.txt

I hope this helps! Let me know if you have any more questions.

Linux strace命令

Linux strace命令是一种调试工具，用于跟踪进程所执行的系统调用和接收的信号。它会输出进程调用的函数、传递给函数的参数和返回值等信息，以帮助开发人员诊断应用程序的问题。strace命令可以帮助开发人员快速定位问题，尤其是在应用程序出现异常时。它可以通过以下命令来使用：

strace [options] command [args]

其中，options是一些可选参数，command是要跟踪的进程或可执行文件，args是传递给进程的参数。strace命令输出的信息可以保存到文件中，以便后续分析。
