I am new to regular expressions. I need help in replacing few filenames.
We have few filenames like abcd.txt.pgp, 1234.xxx.pgp, 4567.yyy.pgp
I must replace the .txt.pgp from file1, .xxx.pgp from file2 and .yyy.pgp from file3 with nothing
In simple terms, Can anyone of you help removing whatever is present after . (decimal). we have a common framework so the filenames will be input and we must remove whatever present after (.). So, there will be only one replace string service.
