fstab-decode(8)             System Manager's Manual            fstab-decode(8)

NAME
       fstab-decode - run a command with fstab-encoded arguments

SYNOPSIS
       fstab-decode COMMAND [ARGUMENT]...

DESCRIPTION
       fstab-decode  decodes  escapes  (such  as  newline characters and other
       whitespace) in the specified ARGUMENTs and uses them  to  run  COMMAND.
       The  argument  escaping  uses  the  same  rules  as  path  escaping  in
       /etc/fstab, /etc/mtab and /proc/mtab.

       In essence fstab-decode can be used anytime we want  to  pass  multiple
       parameters  to a command as a list of command line arguments.  It turns
       output like this:

       /root
       /mnt/remote-disk
       /home

       Into one long list of parameters, "/root /mnt/remote-disk /home". This
       can be useful when trying to work with multiple filesystems at once. For
       instance, we can use it to unmount multiple NFS shares. This program also
       removes whitespace and other characters which might cause programs such
       as mount or umount to fail.

EXIT STATUS
       fstab-decode exits with status 127 if COMMAND can't be run.   Otherwise
       it exits with the status returned by COMMAND.

EXAMPLES
       The following example reads fstab, finds all instances of VFAT filesystems and
       prints their mount points (argument 2 in the fstab file). fstab-decode then runs
       the specified program, umount, and passes it the list of VFAT mountpoints.
       This unmounts all VFAT partitions.

       fstab-decode umount $(awk '$3 == "vfat" { print $2 }' /etc/fstab)
