pathchk: Check pathnames for validity in the current system.

pathchk

$ pathchk ${path1 path2 …}

try on your machine

The pathchk command is used to check the validity and existence of file paths. It is primarily used to verify that file paths specified in environment variables are valid and can be accessed.

The command syntax you provided, pathchk ${path1 path2 …}, suggests that pathchk is being used in conjunction with the ${path1 path2 …} parameter.

In this context, ${path1 path2 …} indicates that multiple file paths are being passed as arguments to the pathchk command. The paths are passed as separate variables or values, listed one after another.

For example, if you have three file paths - /home/user1/file1, /usr/local/bin, and /opt/files/file2, you would use the command like this:

pathchk /home/user1/file1 /usr/local/bin /opt/files/file2

The pathchk command will then check the validity of each individual path and determine whether they exist or not. It may return an error message for any path that is invalid or inaccessible.

Note that the pathchk command can vary slightly depending on the operating system or shell being used.
