compare date of files on different nodes
Hi All,
I´ve got the following problem
I´m implementing a failoverconcept. This requires to synchronize two files using ksh like this.
if HOST1:FILE1 is newer then HOST2:FILE1
THEN cp HOST1:FILE1 HOST2:FILE1
ELSE cp HOST2:FILE1 HOST1:FILE1
fi
How can I compare the files on two boxes?
I tried it on one box and it works
and im able to get the date information with ls -l and awk - like this but how i schould compare the datestrings or how can i change the variable format?
DATE_MAIN=`ls -l FILE1 | awk '$1 !~ /total/ { printf "%-32s \n",$8 ; }'`
DATE_BCKP=`rsh HOST2 ls -l FILE1 | awk '$1 !~ /total/ { printf "%-32s \n",$8 ; }'`
if [ $DATE_MAIN -ge $DATE_BCKP ]
THEN cp HOST1:FILE1 HOST2:FILE1
ELSE cp HOST2:FILE1 HOST1:FILE1
fi
An other idea i got was using the find command with the -newer flag but it didn´t work with an remote Host.
BRGDS & TIA

P.S.
Sorry for my poor english

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.
