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
