Today, I will talk to you about what are the nine bash skills to improve Linux work efficiency, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

I like to delve into the bash environment. Many times, in programming with bash, some problems are encountered over and over again. Every time I need to rethink the solutions to these problems. Until one day I couldn't stand it, so I sat down, wrote a generic function, put it in my .bashrc file, and deployed it on my computer.

I hope my efforts to maximize command-line efficiency will also be of some help to other friends who like to use bash. My greater hope is that my behavior will lead to interaction among other friends-give me advice and better bash skills, please leave a comment at the end of the article.

Nothing else, here is my summary.

Tip 1. Use the command line to add text to the top of the file

Every time I find out how to write this command again. Here's how to use sed to add a line to the top of a file:

Sed-I path/to/file/you/want/to/change.txt tip 2. Insert multiple lines of text into the configuration file using the command line

This method is very simple, and as many people know, here is how to insert multiple lines of text into a file using the command line. The "here document" syntax is used here, which allows you to insert paragraphs into a file through block text symbols, usually using EOF (meaning "End Of File"):

Cat > > path/to/file/to/append-to.txt
