ToolBox -

In the Hyak environment some programs are installed by default but many common programs are not. To prevent duplication of effort by folks at the iSchool, we’ve installed the following programs to /gscratch/ischool/local

  • Nano 2.2.6
  • Emacs 24.3
  • automake 1.9.6
  • autoconf 2.69

To use these applications you can access them directly at /gscratch/ischool/local/bin/ or you can add this location to your .bash_profile.

You can add this path to your .bash_profile in two ways. You can either prepend the path to your $PATH, which will make the binaries installed to /gscratch/ischool/local override the default Hyak binaries. Or you can append it, which will leave the Hyak installed binaries the default, but any binaries not installed on Hyak that are in /gscratch/ischool/local will be used as a backup.


echo PATH=/gscratch/ischool/local/bin:\$PATH > ~/.bash_profile


echo PATH=\$PATH:/gscratch/ischool/local/bin > ~/.bash_profile

These commands will write the new PATH definition to your .bash_profile. If you’ve modified your .bash_profile you might want to manually edit rather than just writing it to the end of the file.

If you have a software request that you think other iSchool Hyak users can benefit from feel free to contact the iSchool IT helpdesk to have that software installed to /gscratch/ischool/local (or simply request access to install it yourself if you are comfortable doing so).

If you have any questions after reading this article or if you need any help, please don't hesitate to contact the iSchool IT Help Desk.
