Answer 1

Judging from the comments to the other answers, you probably want something like this:

for file in *.ext; do
    customise.pl "$file" "${file%.*}.new.psl"
done

The ${file%.*} syntax substitutes only the part of $file up until its last dot. You can check the manpages for Bash or Dash for more information on it if you need.

Answer 2

another way.

ls *.ext |xargs -i customise.pl {} {}.in

Answer 3

I guess the simplest form is

    for f in "*.ext"
    do                 
         customise.pl  $f.ext $f.ext.in      
    done

OUTPUT:

Answer 4

If you want to run customise.pl for each pair of files, you can do it like this in a bash script:

#!/bin/bash

for i in `ls *.ext`
do
  customise.pl $i $i.in
done

Answer 5

for i in *.ext; do 
    customise.pl "$i" "$i.in"
done
