Shell script for quick navigation upwards in directories :
#!/bin/bash
# ..
# Installation guide:
# 1. Paste this code in a file. Let say - in "/home/{user}/bin" and name it - for example - "goto"
# 2. In .bash_alias add an alias like so: "alias gt=". /home/{user}/bin/goto". NOTE the dot and the interval after it!
# 3. Make sure you've "sourced" the .bash_alias file. (cd ~; source .bash_alias)
# 4. Try "gt" anywhere, with or without parameters
# ..
# Or - to be closer with Shell's naming convention - name the file "goupto" and the alias "alias gut=". /home/{user}/bin/goupto".
# First - check if user specified one parameter ..
if (( $# != 1)); then
