This article is about how to use pss search code under Linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Pss is a command-line tool that helps you search in source code files. Pss recursively searches the directory tree, automatically determines which files need to be searched and which files don't need to be searched based on file names and suffixes, and automatically skips directories that you don't want to search (such as .svn and .git), and can render output in color to make it easy for people to read, among many other features.

Install pss

Install pss on Fedora using the following command:

$dnf install pss

After installation, you can call pss on the terminal:

$pss

Calling pss without arguments or with the-h flag will output detailed instructions for use.

Use case

Now that you have installed pss, let's take a look at some examples.

$pss foo

This command simply searches for foo. You can also restrict pss to search for foo only in python files:

$pss foo-py

You can also search for bar in non-python files:

$pss bar-nopy

Also, pss supports most common source code file types, and to get a complete support list, execute:

$pss-help-types

You can also specify to ignore certain directories and not to search. By default, pss ignores directories such as .git, pycache,.metadata, and so on.

$pss foo-py-ignore-dir=dist

In addition, pss can display the context of the search results.

$pss-A 5 foo

The next five lines of the match are displayed.

$pss-B 5 foo

The first five lines of the matching result are displayed.

$pss-C 5 foo

Five lines before and after the matching result are displayed.
