thanks
Assuming you don't want the line numbers actually in the file, just shown when you cat the file, define an alias 'ncat' (probably not a good idea to alias cat):

Code:
alias ncat="awk '{ printf( \"%4d %s\n\", NR, \$0 ); }'"

Each time you execute something like ncat /tmp/foo the output will be prefixed with line numbers.
