To make it clearer:

I have a file, List.txt
List.txt contains: (these are actually splitted files w/c I got from ls command and dump them to the List.txt file)

SAMPLEa
SAMPLEb
SAMPLEc
SAMPLEd
SAMPLEe
SAMPLEf
.
.
.
.
.

And I want to rename these files to have a .dat extension. (ie. SAMPLEa.dat, etc…)
Please see code snippet below. It’s not working and your valuable suggestion will be highly appreciated.

#!/bin/csh
# Looping

cat list.txt | while read line
do
mv $line $line.dat
done


Thanks in advance for the help…

Hey,

better do the following:

for i in `cat <your textfile>`
do
mv $i $i.dat
done

Greetings,

Nothing wrong with the code except for one (big) point :
In its current form, its incompatible (while expression syntax) with the shell (csh) you wish to use...
Up to you: or you correct it, or you use (what most of us do, for compatibility...) sh or ksh
comment your first line and you will see it work!

All the best

Thanks a lot guys for the help... Got the script now working.... :-)
