[SOLVED] Append string on grep multiple results in a single command

Issue

I want to append a string on the every line from the grep result.

For example, this command will return several lines:

ls -a | grep "filename"

For example:

filename1
filename2
filename3
filename4

How can I append a string test on each return line using a single command? So that I get this output:

test filename1
test filename2
test filename3
test filename4

Solution

You can do this:

ls -a | grep "filename" | perl -ne 'print "test $_"'
