Fixed grep and awk commands.

Commands are indented with a single space instead of two (fixes grep).

$1 was empty; the commands are available trough $2 (fixes awk)
Enable -n for grep command by default. Strip whitespace.

The -n is enabled by default to deal with this option potentially being enabled in bash settings.
