sed substitution
Hi,

I have a set of files containing strings like I.TEST1_TEST2 or B.ESSA_ESSB for example.

Does somebody know how to substitute these strings whith the same name and an extension "_V1" (ie. I.TEST1_TEST2_V1) using sed command or else ?

Try this:
sed 's/\([A-Z]\)\.\([A-Z0-9]*\)_\([A-Z0-9]*\)/\1.\2_\3_V1/'

It's ok.
Thanks for your reply.

If all that your files had were lists of these type of names...then you could also use

sed 's/$/_V1' filename

This would just add "_V1" to then end of each line. Might be easier if this is all that your files have in them.
