Linux
Background: Where to find Software under Linux?
Typical folders where you can find your Software:
local installations in /usr/bin, /bin. Here you can find system tools like editors, shells, and also scientific tools like python and a standard c-compiler. Locally installed software can only be updated by updating the whole operating system.
/client/bin in this folder you can find some software distributed by CEN-IT. During the login process is inserted into the $Path variable. So you can use the software easily by typing the program name into your console.
/sw/<platform>, where <platform> corresponds to the linux version. Here you can find scientific software, which is often available in different version. With the assistance of the module system you can easily load all the versions you want.
