panyam solution works. here I want to mention zsh. Smilie
if you have zsh, with
Code:
setopt BRACE_CCL

your requirement can be as easy as:
Code:
kent$ echo file_{001..100}

output would be:
Code:
file_001 file_002 file_003 file_004 file_005 file_006 file_007 
... 
file_040 file_041 file_042 file_043....
file_099 file_100

If you have the seq command:
Code:
seq 1 10|xargs -I '{}' printf "file_%03d%s\n" {}

Most modern shells also do brace expansion, but it's not a part of POSIX:
Code:
echo {1..10}|xargs -n1|xargs -I '{}' printf "file_%03d%s\n" {}
