A Bit More Information about Setting up your Shell
Note that setting these variables only works in the shell or window
you issue the above commands in. You will need to ensure that the
proper path is set and used for future logins and for other newly
To do so you should also modify your shell's startup file
so that this bin directory will be at the front of your
path each time you log in.
If your shell is the csh or tcsh you should modify
your .cshrc or .tcshrc file appropriately,
as well as your .profile if you plan to be working by logging
in through SSH.
If your shell is the bourne shell (sh) or bash you should
modify your .bash_profile (if it exists, and .profile if it does
not) as well as your .bashrc file appropriately.
On many Unix systems you can find out which shell you are using
by grepping for your userid in /etc/passwd.
grep ^brecht: /etc/passwd
Will give produce the following line:
brecht:x:1204:1204:Tim Brecht,DC 3508,x35892,,:/u4/brecht:/xhbin/tcsh
The last string at the end of the line tells you your login shell.
