SED - editing file names (End of line problem?)
For lists in sed, to say what to replace, is this correct: [$ .]
I am hoping that this would recognise that either a "." is present, or that the substitution happens at the end of the line.
For files with extensions [picture.jpg], my script works perfectly.
My problem is, files without extentions, i.e. [picture]. The script gives the following message for these cases: "picture and picture are identical".

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.
