I have been a Linux user for almost 7 years. I was introduced to it by my undergraduate advisor, Daniel S. Souza, who suggested it to me after I encounter some problems while compiling Fortran codes in Windows. At that time, my knowledge of it was close to nonexistent. Everything I knew about it was related to its ‘difficulty’ of use. Quotation marks is just to highlighted this misconception.

I am a huge fan and enthusiastic of Linux. This is not exclusively due to the fact that it is free, ‘‘free speech, not free beer’’. Its strong terminal-based commands appear to be a great opportunity to perform repetitive tasks very easily with little knowledge of bash. As I am into academia, I will show useful command-line programs to facilitate academic-related tasks. Nonetheless, all code shown here can be easily used and/or adapted for other tasks.
