I would like to know if there is such a way to preset (say, in a .login file)
file permissions so that each time a file is saved, it's permissions will be
those of the preset ones. Thank you in advance for your reply.

Thank you in advance for your reply. Try adding the 'umask' command to your .cshrc. (remember this is a mask, the negation of the mode of protection). Ie: umask 011 would result in a default protection of: 766. >-Erik -Rich -- ------------- rauscher@rutgers.edu RPO 5997 PO 5063, New Brunswick, NJ 08903 rauscher@PISCES Shakespeare learns Discrete Math: {backbone site}!rutgers!rauscher (2B | not (2B)) <=> TRUE

Thank you in advance for your reply. Set the umask to the permission bits that you want turned _off_ when a file is created; a common umask is 022. To set the umask, simply use the umask(1) command, such as ``umask 022''. Whenever you create a file, the creat() call gets your file creation mask from your U area, and does something like this: creat(path,mode) char *path; int mode; { struct user *u; ... mode &= ~(u->u_cmask); ... } Cheers, -- Michael Stefanik, MGI Inc., Los Angeles| Opinions stated are not even my own.
