Shell Script (adding a prefix to output lines)

rheza · 01-04-2005, 01:05 PM

Hello, I'd like to ask about a command in the shell which would allow me to add a prefix to the an output of mulitple lines. Like say when I do a command:

ls

is there a way to prefix it outputs with a string "string here" such that it will look like this

string here file1
string here file2
string here file3
string here anotherfile

instead of

file1
file2
file3
anotherfile

Code:

#!/bin/bash

ls | while read FILENAME ; do
	echo "String here $FILENAME"
done

Or just:

Code:

ls | sed 's/.*/string here &/'

I wasn't really using it for ls, but the second one works great. Thanks Hko!
