Moving old files based on pattern
Hi all

I am trying to loop through a directory of files using a given search pattern. some of the files will be duplicated due to the pattern, but of the duplicate files i wanted to move the older files to another location.

Is there any straightforward way of doing this ?

One of ways I thought of is using
Code:
ls -ltr IGL* | head - 1 <> ls -ltr IGL* | tail -1

This should give give me only the older files, but im not sure how to put this in a loop

Any help appreciated

Thanks

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
