I have recently installed Code Sourcery's ARM EABI Tool Chain. All the executable binaries were installed in a separate folder.
I thought that the bin path will be added to env variable $PATH. However, after installation I was unable to run, as the bin path was not added to the env variable.
So, I removed the directory, downloaded just the binaries (not installation package).
I would like to set an environment variable (that will we will call "TEST") to store the path to a sub-directory of my home directory : something like /home/myself/dir/. I would like to use the $HOME variable so that the system can get a path that is valid for any user on the system (provided they have a directory called "dir" in their home folder).
