How to rename files

Hi Guys,

I have to rename about 180 files in different folders in linux. For example,

abc_110117.txt
eff_110117.txt
zzz_110117.txt

After renaming the files, these files should like like

abc.txt
eff.txt
zzz.txt

I created a small script to rename the files like

ls $COMP_FILE_DIR/*.txt > $COMP_FILE_DIR/change_file_name.txt
while read line
do
FILE=$(echo $line | cut -f1 -d\_)
FILE_NAME=$(echo $FILE'.txt')
mv $line $FILE_NAME
done < $COMP_FILE_DIR/change_file_name.txt
rm $COMP_FILE_DIR/change_file_name.txt

But because of time contraints and using different folders, I have to spend too much time to rename the files.

Is there one command that I can run to rename the files.

Thanks a lot.

Naveed

BOMSTRIP(1)						    BSD General Commands Manual 					       BOMSTRIP(1)

NAME
bomstrip, bomstrip-files -- strip the BOM sequence from UTF-8 files SYNOPSIS
bomstrip bomstrip-files file ... DESCRIPTION
The bomstrip utility reads UTF-8 data from its standard input and copies it to its standard output, stripping the BOM (byte-order mark) from the beginning of the text if it is present. There are no command-line options and no parameters. The bomstrip-files utility removes the UTF-8 BOM from the specified files, saving each file's original contents with a .bom extension. It uses the bomstrip utility, trying to execute it as ``bomstrip''; if the bomstrip utility is installed under another name, or if a more com- plex command is desired, it may be supplied in the BOMSTRIP environment variable. EXAMPLES
Strip the BOM, if present, from a text file: bomstrip < bom.txt > nobom.txt Strip the BOM, if present, from all text files, backing them up with a .bom extension: bomstrip-files *.txt Use the OCAML implementation of bomstrip: env BOMSTRIP='ocaml bomstrip.ocaml' bomstrip-files *.txt SEE ALSO
The bomstrip home page: http://www.xs4all.nl/~mechiel/projects/bomstrip/ HISTORY
The bomstrip utility (in many languages) was written by Mechiel Lukkien, with implementations in various languages sent to him by others, including Andreas Gohr, Andrew Gerrand, Berteun Damman, Matthijs Bomhoff, Peter Pentchev, and Ruben Smelik. The bomstrip-files utility and this manual page were written by Peter Pentchev in the hope that they reflect the behavior of all the bomstrip implementations in all lan- guages. AUTHORS
