run my command
fi
Would a | command work?

MELD(1) General Commands Manual MELD(1)
NAME
meld - Visual diff and merge tool for the GNOME Desktop
SYNOPSIS
meld [options]
meld [options] FILE1
meld [options] DIR1
meld [options] FILE1 FILE2 [FILE3]
meld [options] DIR1 DIR2 [DIR3]
DESCRIPTION
Meld is a graphical diff viewer and merge application for the Gnome desktop. It supports 2 and 3-file diffs, recursive directory diffs,
diffing of directories under version control (Arch, Bazaar, Codeville, CVS, Darcs, Git, Mercurial, Monotone, RCS), as well as the ability
to manually and automatically merge file differences.
OPTIONS
--auto-compare, -a
Automatically compare all differing files on startup.
--diff FILE1|DIR1 FILE2|DIR2 [FILE3|DIR3]
Create a diff tab for the given files or directories. Note that "meld --diff FILE1 FILE2" is functionally equivalent to "meld FILE1
FILE2". However, the --diff argument can be given multiple times for one invocation of meld which allows the user to automatically
initiate multiple diffs when meld starts. See examples below.
--help, -h
Print application help and usage.
--LABEL=<label>, -L <label>
Set application window title to <label>.
--version
Print application version and exit.
EXAMPLES
meld
Run meld without initiating a diff.
meld FILE1
Initiate a diff between FILE1 and the version-controlled copy of FILE1.
meld DIR1
Initiate a recursive diff between DIR1 and the version-controlled copy of DIR1.
meld FILE1 FILE2
Initiate a diff between FILE1 and FILE2.
meld FILE1 FILE2 FILE3
Initiate a 3-way diff between FILE1, FILE2, and FILE3.
meld DIR1 DIR2
Initiate a recursive diff between directory DIR1 and DIR2.
meld DIR1 DIR2 DIR3
Initiate a recursive 3-way diff between directory DIR1, DIR2, and DIR3.
meld --diff FILE1 FILE2 --diff FILE3 FILE4
Initiate a diff between FILE1 and FILE2, and a separate diff between FILE3 and FILE4.
