Need help in shell script to trim numeric values

Shell Programming and Scripting
1

Hello

I am currently working on a shell script which actually needs to pull some file

from a server ,

The filenames will have the extension with date/time stamp , i need to trim that and name it to proper format

Example :

xyz_20091108_22142365.gzip

i need to remove the numbers from that and name it to xyz.gzip

i know i can use mv for these but i have huge number of files with different names and with different time stamps .

Please suggest a method to trim the numeric values(date/timestamp) without using a mv command.

Thanks for your help!!

file=xyz_20091108_22142365.gzip
newfile=${file%%_*}.gzip

Or, if the suffix could change:

file=xyz_20091108_22142365.gzip
newfile=${file%%_*}.${file##*.}

Thanks for your reply,,

it displays the file name , but i need to have the new file name in the directory instead of the one which has the timestamp

xyz_20091108_22142365.gzip should be replaced by xyz.zip in the same directory

but it displays the file name but the actual file is not there.

Thanks for your help again !!

mv "$file" "$newfile"
