I'm using the below command but .txt is appended to the beginning of the file names not in the end. how to display it like filename.txt?

for test in `cat files.lst`; do echo $test".txt"; done

.txtrce
.txt
.txtge
.txttion
.txt
.txtheist
.txtave
.txt_tion

Thanks

What happens if you try:

Code:

for test in `cat files.lst`
do
  echo "${test}.txt"
done

Code:

for test in `cat files.lst`
do
  echo "${test}\c"
  echo ".txt""
done

Code:

for test in `cat files.lst`
do
  x="${test}.txt"
  echo $x
done

No output for the 2nd one. For the rest,

.txtrce

.txtge
.txttion
.txt
.txtheist
.txtave
.txt_tion

Thanks

Having actually tried the code now (and having had to correct the error in the second one (removing the extraneous "), plus adding -e to the echo (needed as I am using bash under Linux to have the \c work)) they have all worked as planned. Indeed, as I suspected, your code also works, which makes me think that the source of the problem is your file. I suspect you have blank lines interspersed within it - add a pipe to your cat to remove them: (| grep -v "^$") and see how that goes:

Code:

for test in `cat files.lst | grep -v "^$"`; do echo $test".txt"; done
