NAME
       if - conditionally execute a command

   Synopsis
       if CONDITION; COMMANDS_TRUE...;
       [else if CONDITION2; COMMANDS_TRUE2...;]
       [else; COMMANDS_FALSE...;]
       end

   Description
       if will execute the command CONDITION. If the condition's exit status
       is 0, the commands COMMANDS_TRUE will execute. If the exit status is
       not 0 and else is given, COMMANDS_FALSE will be executed.

       You can use and or or in the condition. See the second example below.

       The exit status of the last foreground command to exit can always be
       accessed using the $status variable.

   Example
       The following code will print foo.txt exists if the file foo.txt exists
       and is a regular file, otherwise it will print bar.txt exists if the
       file bar.txt exists and is a regular file, otherwise it will print
       foo.txt and bar.txt do not exist.

       if test -f foo.txt
           echo foo.txt exists
       else if test -f bar.txt
           echo bar.txt exists
       else
           echo foo.txt and bar.txt do not exist
       end

       The following code will print 'foo.txt exists and is readable' if
       foo.txt is a regular file and readable

       if test -f foo.txt
          and test -r foo.txt
          echo 'foo.txt exists and is readable'
       end
