Hi, I often have the case where I want to open up an area of a directory to group access. However I am using SCCS and have many files that should remain read only. A mindless chmod -R g+w . Trashes the sanctity of SCCS by making some things group writable while they aren't user writable. How can I cleanly execute this command? awk/sed/sh/find (or whatever) accepted Please no PERL or CSH. SunOS4.1 (but please don't make it specific to that platform) -- | () () () | Frank P.

To add group read & write permissions to any file here or lower that's writable to the user: find . -perm -0600 -exec chmod g+rw "{}" \; -Kartik -- internet# ls -alR | grep *.c subbarao@{phoenix or gauguin}.Princeton.EDU -|Internet kartik@silvertone.Princeton.EDU (NeXT mail) -| SUBBARAO@PUCC.BITNET - Bitnet

Yesterday I said : >>Hi, >> I often have the case where I want to open up an area of a >>directory to group access. However I am using SCCS and have many files >>that should remain read only.

I guess I didn't quite get the meaning of = and the phrase : The letters u, g, or o indicate that permission is to be taken from the current mode for the user-class. This is being sent to try and stem the tidal wave of answers. -- | () () () | Frank P.
