[problem]
You want to number each line of output.
[/problem]
[solution]
Again other ways to do this with UNIX, such as grep -vn XXXX filename.
But sure there are times you want the line number, of standard input.
[/solution]
[example]
echo "testingntestingn123" | perl -e 'while(<>) {
chomp();
print($..": ".$_."n");
}'
1: testing
2: testing
3: 123
Or all on one line
echo "testingntestingn123" | perl -ane 'chomp();print($..": ".$_."n");'
1: testing
2: testing
3: 123
[/example]
