makkays · 11-21-2006, 10:09 PM

hello,

there was previous related thread to umask question but it was unable to satisfy my problem.

1.If i change defualt umask will that same umask be aplicable to both files and directories or it will be for only files or directories.

2. i am logging through Root.now i wish to change umask to 022.in which file i have to mention it and what will be the coding command which i will have to write in the file.

thanks

Yes it should apply to both files and directories
Hopefully you are only logging in as root when doing sysadmin and not daily use. You can put the umask value in your ~/.bash_profile or /etc/profile e.g.
Code:
```
umask 022
```

If you're even unsure, just test it.

Code:

for testmask in 012 345 677; do 
  umask $testmask
  mkdir $testmask.d
  touch f$testmask.f
done
ls -l

This table summarizes the results:

Code:

umask :  0   1   2   3   4   5   6   7
dir   : rwx rw- r-x r-- -wx -w- --x ---
file  : rw- rw- r-- r-- -w- -w- --- ---

If the octal argument confuses you, you can use symbolic mode:

Code:

umask a=rx,ug+w

The manual page describes this in more detail, and has quite a few examples.
