Linux system How to bulk find files and file content

Like finding a keyword in all of the PHP files underneath the current directory.

The code is as follows	Copy Code
Find./-name "*.php" | xargs grep ' keyword '

If you need to find something that contains special symbols, such as $, and so on, grep adds parameters

The code is as follows	Copy Code
Find./-name "*.php" | Xargs grep-f ' key word '

File name Lookup

File Name Lookup method:

For example, if we know that a file contains 3 letters of SRM, it is possible to find all files containing these 3 letters in the system, and enter:

The code is as follows	Copy Code
Find/etc-name ' *srm* '

This command indicates that the Linux system will look for all files containing 3 letters of SRM, such as ABSRMYZ,TIBC.SRM and so on, in the entire directory of/ETC to display the eligible files. If you also know that this file starts with the 3-letter SRM, we can also omit the front asterisk, which commands the following:

The code is as follows	Copy Code
Find/etc-name ' srm* '
