Use the find command to locate files

The find command is a very commonly used command in Linux systems. It is used to find files in a specified directory. Through the find command, we can find files based on different conditions and perform some operations on the files. Below I will introduce you to the use of find command and give some specific code examples.

1. Basic usage

The basic syntax of find command is as follows:

find [path] [option] [expression]

Where, path Indicates the directory to be searched, which can be an absolute path or a relative path. Options represent some parameters of the find command, used to set some specific search conditions. Expressions are used to set some operations of the find command, such as copying and deleting found files.

2. Commonly used options

The following are some commonly used options, which can be selected according to actual needs:

1. -name: Search according to the file name. For example, -name "*.txt" means to find all files whose file names end with .txt.
2. -type: Search according to file type. For example, -type d means to search a directory, and -type f means to search for an ordinary file.
3. -size: Search based on file size. For example, -size 10M means to find files larger than 10M.
4. -mtime: Search based on file modification time. For example, -mtime 30 means to find files modified 30 days ago.
