Search in configuration files
As I receive no answer from the experts to my thread "Compose new symbols with the keyboard" ( ... and I have made the enquiry on several forums !), I ask something simpler to solve the problem myself.
I need to find out a special symbol (for ex. "²" - which I obtain with AltGr 2) in the configuration files generated by Mandrake 10. I have a USA keyboard without Win keys and the AltGr is for me merely the Alt key on the right.
My question is: using grep or whatever, how can I search for a given symbol or character in all the file system (beeing probably root), limiting the search, if possible, to configuration or text files?
but it doesn't work...
