Top Forums UNIX for Dummies Questions & Answers how to get the timestamp using touch command Post 302265935 by Lakris on Monday 8th of December 2008 11:25:40 PM

Hi, are You saying that the time stamp is in the file name or is it the actual time stamp of the file You want?
Using
Code:
touch -r file.txt file1.txt

will give file1.txt the same access and modification times as file.txt.

If it's in the filename I can't see what the problem is, You already have the filename that You want to use? You use it in the grep statement? You can do something like this:

Code:
orgname=file.08
grep "name" $orgname > $orgname.tmp
mv $orgname.tmp $orgname

And about getting previous "workday", well this might not be the neatest, but anyway... given You run it on a workday:
Code:
[ $(date +%u) -eq 1 ] && prevwday=3 || prevwday=1
prevwdaynumber=$(date -d "$prevwday days ago" +%d)

Best regards,
Lakris

PS And about Your third original question, why does this look so much like a homework? Smilie
I'm not sure about cut but tr would do the trick just fine...

tr , "\n" < file.txt

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
