then you should be able to do
filenames = glob ([dir + "/freqspec-*.dat"])

to get the names of your files.

You think wrong. "glob" has been available at least since 2.9.x. Just
try "help glob".

Must be an older system. I think new Fedoras have 3.2.x. In any case,
Octave has little to do with what Linux OS it is being run on.

Sorry for not being kind. I guess I'm a little annoyed by people not
understanding obvious (to me) advices, not reading manuals (as if I
always do that) and asking questions in poor english (as if my english
was excellent) without giving relevant (for me) information.

Time to take a break, I suppose.
