compress file

peterchu — Mon, 22 Aug 2005 01:50:48 GMT

In the directory /tmp , there are some files and new files will be generated into it, I want to regularly archive the files into one by tar , for simple manage the file , I want to add date and time to the end of file ( eg. if I archive it at 10 Aug 05 , 10:00am , the file name should be file.10Aug05-10:00am , could suggest how to do it ? thx in advance.

Do something like this
filename=`date '+%d%b%y-%I%p'`
tar cvf /$filename.tar /tmp/
Does it solve what you want

Hi,

It is allthough not suggested to archive all these files as many of these files will be opened by running processes.

Allthough try this by writing a small script and then calling this script manually or through crontab/at.Define following two line apart from other general ones in your script.
========================================
TIMESTAMP=$(date +%m%d.%I%M)
tar -cvf /tmp/tararchive.TIMESTAMP /tmp/files
========================================

This will stamp time in all the files created but your syntax will be slightly different. But this I think is enough for you to start with.

HTH,
Devender

It is suggested to do this archive execution @ non-working hours. i.e) /tmp directory access has to idle so that it will be successful else problem will come bcas of opened files.

You can do archive as,

tar -cvf archive_$(date +'%d%b%y-%H:%M%p').tar /tmp/*
[[ $? -eq 0 ]] && echo "Tar execution is success @ $(date +'%d%b%y-%H:%M%p')"

hth.

Just change as,

tar -cvf /tmp/archive_$(date +'%d%b%y-%H:%M%p').tar /tmp/*
[[ $? -eq 0 ]] && echo "Tar execution is success @ $(date +'%d%b%y-%H:%M%p')"

hth.
