Basics
You account has one last thing that needs to be edited before being usable.
- SSH into Hoffman2
- Use your favorite text editor to edit the file
~/.bash_profile, e.g.$ vim ~/.bash_profile
- or
$ emacs ~/.bash_profile
- Insert these lines at the bottom of the file
source /u/home/FMRI/apps/etc/profile umask 007
- Save the file
- Log out of Hoffman2 and the next time you log in, everything will be set for you to start working.
Curious?
For those that care, what you are doing is asking the computer to execute the file
/u/home/FMRI/apps/etc/profile
every time you login. This file modifies your PATH variable so you have access to the FMRI toolset.
The last line
umask 007
makes it so that any files you create will have a default permission of about 770 so that other people in your group have write permissions.
Extras
You can change the content and color of your command prompt by editing your bash_profile. There is a great explanation of how to do this here.
Some of the content you can include in the command prompt:
- Current time
- You can format this however you want. This helps when looking back through your Terminal to find when you made certain changes to files.
- Current working directory
- So you always know where you are in a filesystem and don't need to constantly retype
pwd. - Username
- Who you are. Helpful if you are logged into multiple servers under multiple accounts and need help keeping track.
- Host
- The name of the computer you are logged into. This also helps you know where you are at all times.
