Delete first line from file and more....
Hello, I have to deal with several files that will be named something like this:
E00001.TXT, E00002.TXT etc.
Each file will have a alpha character on the first position of the first line which I want to place in a variable, then delete the entire line leaving the remainder of text. This new file I want to be named the original filename prefixed by the character I previously extracted so the new file might be RE00001.TXT. Usually, out of habit I call tcl scripts to do file manipulation but I wanted to know if there was a fairly starighforward way to do this all in my Unix script (ksh). I don't know much about sed or awk so if you give examples with that and don't mind providing a brief description of what does what that would be helpful. Could the grep command provide all the functionality I'm asking for?
TIA
