Suppose you have a program that is generating log files every day, let's say they are key performance indicators (kpi) for some system that you are testing. The log files are pure text, but after a while, they take up a lot of space. One way to compress text is to use gzip, but since tar has an option (-z) to tar and gzip all at once, it may be one of the easiest solutions. #!/bin/sh # compress logs in /opt/multicast_kpi/record # by ScottM, 20080613 # Set variables TODAY = " `date +%m%d%Y` " ARCHIVE_DIR =/opt/multicast_kpi/record # move to working directory cd $ARCHIVE_DIR # For each subdirectory, make a .tgz file of it's contents, and then delete the originals. for dir in `ls -1 $ARCHIVE_DIR | grep -v " .tgz " | gre...
