Common commands used when working in terminal/linux based systems
=================================================================

.. code-block:: csh

   #       comment 
           This symbol (#) is used to write notes in code that will not be read or interpreted when you run a script (series of commands used to process the data)

   cd      change directory
           example: cd Desktop/Aarons_Files
             This will move you into a directory (folder) on the desktop called "Aarons_Files"

   ls      list (view) everything in your current directory

   pwd     print working directory
           command used to tell you exactly where you are on a computer
           this can be very useful when navigating to specific locations/files or writing processing scripts
             example: pwd
               /Users/aaronjacobson/Desktop/Aarons_Files

   cd ..   change directories to ONE directory before/above your current location
           example: 
             cd /Users/aaronjacobson/Desktop/Aarons_Files
               cd ..
                 pwd
                   /Users/aaronjacobson/Desktop/

   cd ../..    change directories to TWO directories before/above your current location
           example: 
             cd /Users/aaronjacobson/Desktop/Aarons_Files
               cd ../..
                 pwd
                   /Users/aaronjacobson/

   *     wildcard
           used to take a shortcut to a directory or include multiple files in a process (among other uses)
             example: cd Desktop/Aarons_F*
               This will move you into a directory on the desktop that STARTS with "Aarons_F". If Aarons_Files is the only directory that meets this criteria, that is where you will go
             example: cd Desktop/*ons_Files
               Move into a directory that ENDS with "ons_Files". If Aarons_Files is the only directory that meets this criteria, that is where you will go
             example: cd Desktop/*ons_Fil*
               Move into a directory that CONTAINS "ons_Fil". If Aarons_Files is the only directory that meets this criteria, that is where you will go

             example: cp Desktop/Aarons_Files/fakefiles_* fake_directory
               copy (cp) every file within the Aarons_Files directory to a directory called "fake_directory"

   /~      your HOME directory
           This is your base folder on your user account on your computer. when you open Terminal, this is where you will start.
             example: cd ~/
               pwd
                 /Users/aaronjacobson/
             example: cd ~/Desktop
               pwd
                 /Users/aaronjacobson/Desktop
