If there are no leading spaces (that your awk code permits) and no further words on the line, you can try
Otherwise you can take the RudiC solution (with optional space at the beginning, but without the extra space at the end)
or with a Unix sed

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
