Windows
Login files contain commands that are run automatically at login. There are two:
- login.bat, located in H:\CTC Tools\, is run for everyone on the system. The commands it runs include changing to the user's home directory and setting up temporary space. The last thing it does is run userlogin.bat from the user's home directory, if it is present.
In effect, login.bat runs when you login. Specifically, login.bat runs when
- you (or a program you run) open a Command Prompt on a winlogin machine or on a collaboratory machine.
- you ssh to a CTC login machine or use a remote desktop connection to a compute machine.
- your batch job begins.
- userlogin.bat, located in your home directory, can be used if you want to customize your environment at login, or there are commands that you want run each time you log in.
You can write userlogin.bat from scratch, or you may want to start with a template provided in H:\CTC Tools\userlogin.bat. This template contains many typical commands, with all actions commented out. If, for example, you want to be able to use EMACS as your editor, or you often run Fluent on the batch nodes, you should make a copy of userlogin.bat, edit it to uncomment the appropriate setup commands and save it as H:\users\your_userid\userlogin.bat.
Linux
- bash shell: runs .profile in home directory.
- tcsh shell: runs .tcshrc in home directory.
Your Turn
Copy userlogin.bat to H:\users\your_userid\ using one of these methods:
Now edit userlogin.bat and uncomment the lines you wish to execute.
