• the parameter to use is umask https://en.wikipedia.org/wiki/Umask

  • on a cluster I get

    $ umask
    0022
    $ touch test
    $ ls -l test
    -rw-r--r-- 1 perrinet.l invibe 0 Nov 28 11:32 test
    $ umask u=rwx,g=rwx,o=
    $ touch test2
    $ ls -l test2
    -rw-rw---- 1 perrinet.l invibe 0 Nov 28 11:33 test2
    
  • so I did:

    perrinet.l@frioul:~$ vim .profile
    
    # ~/.profile: executed by the command interpreter for login shells.
    # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
    # exists.
    # see /usr/share/doc/bash/examples/startup-files for examples.
    # the files are located in the bash-doc package.
    
    # the default umask is set in /etc/profile; for setting the umask
    # for ssh logins, install and configure the libpam-umask package.
    #umask 022
    # https://en.wikipedia.org/wiki/Umask
    umask u=rwx,g=rwx,o=
    
    # if running bash
    if [ -n "$BASH_VERSION" ]; then
        # include .bashrc if it exists
        if [ -f "$HOME/.bashrc" ]; then
            . "$HOME/.bashrc"
        fi
    fi
    
    # set PATH so it includes user's private bin if it exists
    if [ -d "$HOME/bin" ] ; then
        PATH="$HOME/bin:$PATH"
    fi
    
  • before loging out I have

    perrinet.l@frioul:~$ umask
    0022
    
  • and after

    perrinet.l@frioul:~$ logout
    Connection to frioul.int.univ-amu.fr closed.
