Messed Up Your .bashrc file? How To Fix your Linux Desktop?[Fix]

I messed with the file by adding a PATH variable for Laravel. I added the script in the bottom of file. Saved the file. Than we need to compile the file using source command. I did source ~/.bashrc in terminal. Than something got screwed. Terminal now doesn’t execute any command. Type ls, dir,whoami, cd nothing works. So yours case might also be similar.

How to fix it then?
