To install strace on a FreeBSD system, you can use the pkg package manager.
pkg update
strace by running:pkg install strace
This will install the latest version of strace on your system.
strace has been installed correctly by running the following command:strace -V
This should output the version of strace that you have installed, similar to the following:
strace: version X.X
Note: Replace X.X with the version number of the
straceinstallation that you have.
To use strace, you can run the strace command followed by the name of the program you want to trace, for example:
strace ls
This will trace the ls command and display a list of system calls made by the ls command.
