do it with the command umask

=> umask 774 (fe)

check also 'man umask'

you can set umask in your $HOME/.profile so you have this settings after each login.

754
user is rwx
group is r-x
other is r

In order to create files with permissions
-rwxrwx---, a umask of 007 would be required; however, that still won't work because there are two things in play when files are created: mode and umask. Umask then "subtracts" (actually a bitwise NAND) from the mode to yield the effective mode (permissions) of the new file. However, umask cannot "subtract" what is not already there. The mode for regular files under the shell is -rw-rw-rw- (666) and for directories it is -rwxrwxrwx (777). No setting of umask will ever set the execute bit on a file created in the shell. You must do an explicit chmod after the file is created. If you are creating a file under other circumstances (Perl, C, ...) then you can assert the mode of the file as you create it and do it without an explicit chmod.
