[SOLVED] Permissions with umask


if i type

$ umask 002
$ touch hello
$ ls -l
-rw-rw-r--   1 myname mygrp      0 Nov 19 02:16 hello
The umask is what u subtract from a octal chmod value right? Where is the "x" execute then? I set it to 0 for owner and group, they still dont have the execute permission set.

-> ?? Why

because by default files are not executable - would be pretty useless to have all text files, jpg files, etc. executable :-)

you have to "chmod +x" or use a program being "clever" enough to know it creates executble files (e.g. gcc :-) to set the "x" bit.
