Need the following rights when a user creates a file as the default.

rwxrw-r--

I think I need to change the umask. What file do I change and what umask do I need? bashrc is set umask 0000.

thx

Umask isn't usually a file. It's a command you run, usually in one of the startup files (/etc/profile, the user's ~/.profile, ~/.bashrc or something like that.)

The umask you want is "013". The rule for a umask is to start off with full permissions (777). Then subtract the umask from that. In this case 777 - 013 = 764 (7 is rwx, 6 is rw-, and 4 is r--, which is what you want.)


If you mean there's a "umask 0000" in .bashrc, then change it there. If you don't mean that, I'm not sure what you mean, because a file can't be "set umask". (You might be getting that confused with setuid, which is a slightly different animal.)

Hope this helps,

Yes that fixed me up. I changed /etc/bashrc to umask 0013. That changes the default file rights for everyone to what I needed. Tanks a ton.

Wul crud. I have one user that still creates files as rwxr--r--. The user is running Word in windows and saving the file on the linux server. Anyone have any ideas. I changed umask in etc/profile to 0013. Also have changed the users .bashrc to 0013. I'ma STUCK.

So you running samba. See man smb.conf. Look for 'create mode', 'force create mode', 'directory mode' and 'force directory mode'. Using these options you can do everything with permission rights.

Perfect. That was exactly what I needed to do. Thank you!

Need the following rights when a user creates a file as the default.
rwxrw-r--
* Files on a local Linux filesystem are NOT created with execute and "special" bits set. Since execute mode isn't set for files per default, 0013 means for file creation (write=4, read=2 and exec=1): limit "user" bits to 6, group limit 6, and world limit 2. The umask for these users should be "002".

* Setting 0013 as default umask is just plain wrong. Any user that sources /etc/bashrc, /etc/profile or wherever you set the umask will have their umask set to this value. If you need to centralize a non-std umask value for Sh and Bash users, and keeping in mind how interactive/non-interactive shells source their files, what you should do is set a sane default umask and do something like this (note a default box has all human UID's above 500):
umask 027; if [ "$(id -u)" -gt "500" ]; then umask 002; fi
Or, if you have just three UID's 501 561 and 990187 who need it set:
case "$(id -u)" in 501|561|990187) umask 002;; *) umask 027;; esac

* Keep in mind umask isn't a read-only variable, so any user is allowed to reset it's value.
