Calculate sum of the file size
ls -l access_log.2008-12-20*|gawk ‘{a+=$5;} END {print a;}’
Edit special lines using regular expression
awk ‘/aaa/ ‘ filename
Change file names using sed
##Example: from access_log.2008-12-20.01.gz.1 to access_log.2008-12-20.01.1.gz
for file in `ls access_log.2008-12-20.*`
do
newname=`echo $file|sed ‘s/\(access_log.2008-12-20.[0-9][0-9]\).gz.\([0-9]*\)/\1.\2.gz/’`
size=`ls -l $file|awk ‘{print $5}’`
if [ $size -gt 100 ];then
echo “$file-> $newname”
fi
mv -v $file $newname
done
