I have one file name: cpu_stat_oct152003

i need on script cut cpu_stat because my new file is : saroct152003,

Your question is not entirely clear to me.
If you need to transform the first string
into the second then here are a few examples:


echo cpu_stat_oct152003 | awk -F_ '{print "sar" $3}'

echo cpu_stat_oct152003 | awk '{split ($0,words,"_"); print "sar" words[3]}'

echo cpu_stat_oct152003 | awk '{sub("cpu_stat_","sar"); print}'

hth,
Hein.

or without even using awk

oldname="cpu_stat_oct152003"
newname="sar${oldname##*_}"
