Hi,

Use "ls treasury*|cut -c1-22"

Enjoy :)

Phil; try this

filename=treasury_server.SCANTU.1.205.219.16.253.06-14-05.09:42:57.log
newfilename=`echo $filename | cut -d"." -f1`

the newfilename shouldbe "treasury_server"

Hope it helps.

awk -F "." '{print $1,$2}' "your_file"

if you want the output to include SCANTU as well

ls | cut -d. -f1-2

if not

ls | cut -d. -f1

if you have multiple file like treasury* you can put thw wildcard pattern instead of filename here as well.

hope it helps

How about-

x="treasury_server.SCANTU.1.205.219.16.253.06-14-05.09:42:57.log"
echo ${x%SCANTU*}

This will strip off the SCANTU also, but you could add that back on...

Slight variation on RAC's solution...

echo treasury_server.SCANTU.1.205.219.16.253.06-14-05.09:42:57.log | awk -F".1" '{print $1}'

enjoy!

You can do as,

echo treasury_server.SCANTU.1.205.219.16.253.06-14-05.09:42:57.log | sed 's/SCANTU.*/SCANTU/'

echo treasury_server.SCANTU.1.205.219.16.253.06-14-05.09:42:57.log | cut -d '.' -f1,2

hth.

Rodney's approach is by far fastest one, since it does not use external commands. All others are breaking a fly on a wheel, IMHO.

All of these are good. I used awk.
Thanks for everyone who responded!
