Grep is a Linux text-manipulating utility that searches for a string of characters or patterns known as regular expressions in a file or text. Although I have used Emacs, I definitely prefer Vim. It also covers their most basic functionality and examples for better understanding. Besides actually editing text files, the other tool I use that requires the most editing is the Bash shell. The article covers the best Linux tools to read files and use regular expressions to perform operations on the selected text.
Even though these text manipulation tools differ in complexity and functionality, they come in handy in an environment where the graphical user interface isn't available.
From editing configuration files to writing scripts and even full-blown applications, Linux programmers rely on text editors every day, so it’s no wonder that they spend a lot of time arguing which Linux text editor is best for programming. Take Linux text processing tools as an example, they are lightweight and have modular functionality. A text editor is a programmer’s best friend. Linux developers follow the philosophy of creating small programs that do one task and do it well.
