pwdx

Print current working directory of a process

$ pwdx [process_id]

pwdx pid [pid ...]

pid
    The process ID(s) of the process(es) whose working directory should be displayed.

The pwdx command is a simple utility used to determine the current working directory of one or more running processes. It takes process IDs (PIDs) as arguments and displays the corresponding directory path for each specified PID. It's a valuable tool for system administrators and developers troubleshooting applications or investigating process behavior. pwdx uses the /proc filesystem, a pseudo-filesystem that provides an interface to kernel data structures. It relies on reading the 'cwd' symbolic link located under /proc/[pid]/ to get the directory. It can be helpful for debugging process-related issues. Note that you need appropriate privileges (usually root or same user as the process) to inspect the working directory of other processes.

If the specified PID does not exist or if you do not have the necessary permissions to access the process's information, pwdx will output an error message.
