Yep, that'll work. Your need (something quick to pass over a static set of data, or something that will be used on an ongoing basis) will likely influence what you write in the future. I prefer generic solutions especially if the script will be used on an ongoing basis. Your alternative would be very quickly implemented if you just needed it for a one time shot.

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).
