Bash function that allows to go up to a certain directory.
Stop counting how many levels you have to go up in a folder tree and just type where you want to go! No more cd ../../../...
Current dir /home/username/myfolder/myproject/mysubproject/function1/subfunction2/
If you want to go to /home/username/myfolder/myproject you just type upto myproject
upto will go to the highest folder matched, in the previous example, if you write upto my you will move to /home/username/myfolder
Just add upto.sh to your /etc/profile.d/ folder.
