Remember anyone can run the file but it doesn't mean the programme can write to the directory, so this is most likely the problem. For security, startloopstop should not have write access, so should be set to either 755 or 555. > 2.

The x signifies the password is kept in a separate file called /etc/shadow (the original passwd format held the actual password in that field but was moved to a different file for security (only root has access to /etc/shadow). > 2b.

At the bottom of this file is the single line umask 022. sequence of startup-files for sh, ksh, bash: 1. /etc/profile, 2.$HOME/.profile csh: 1. /etc/.login, 2. $HOME/.cshrc, 3. $HOME/.login > 3. In a csh, how do I find where I am? csh all commands are the same as bash or sh, but uses .login and .cshrc instead of .bashrc or .bash_profile when you logon or start a csh. Check if both of these files exists. Path will be set using set path = ($path $home/bin .) > 4. In a csh, should appropos work?
