In a script that line specifies the interpreter to use to execute the following lines on the script. It may be any interpreter that you want: bash, sh, ksh, perl, python,etc.. In .bashrc, .bash_profile or other files that are "included" from other interpreter/scripts you dont need the interpreter line. As a note, if you are planning to write portable scripts, please use #!/bin/sh and avoid "bashism" (like [ $foo -ge 1 ]) in the syntax.
