Top Forums Shell Programming and Scripting Search for a recently updated file Post 302559183 by Tommyk on Monday 26th of September 2011 11:19:28 AM

Code:
ls -lart *.dat|grep -v resend | tail -1

returns the listing in ascending time modified order of only files ending in .dat, removes anything containing resend in the line, and shows only the last line (the most recently modified)

however, if you have directories in there with an extension of .dat (unlikely) use the following.

Code:
ls -lart | grep -v resend | grep .dat$ |tail -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. AUTHOR
