It be time to learn you some stuff!
My book Perl One-Liners together with many other great books is in Learn You Some Code Humble Book Bundle put together by my publisher No Starch Press.
My book will make you the command line ninja; the shell warrior; the terminal god; the console senpai. You'll be able to solve problems in seconds that take mere mortals hours and even beat Larry Wall at his own game. While Python programmers will be indenting their code and C programmers will be compiling their programs, you'll already be done with the job.
