How to get full path of a file?

Is there an easy way I can print the full path of file.txt ?

file.txt = /nfs/an/disks/jj/home/dir/file.txt

The <command> 

dir> <command> file.txt

should print

/nfs/an/disks/jj/home/dir/file.txt
Solution

  • Use readlink:

    readlink -f file.txt

    The readlink man page (dated Jan 2025) now contains this note:

    realpath(1) is a better command for canonicalization functionality.

    Accordingly, use realpath:

    realpath file.txt
