35 Practical Examples of Linux Find Command

The Linux find command is one of the most important and handy commands in Linux systems. It helps you search and locate files and directories on your system. It can also be used to search for files and directories and perform subsequent operations on them. In this article, we will explain 35 practical examples of the Linux find command.

1. Find Files by Name

The most basic form of the command searches for files in the current directory and recursively through its subdirectories that match the supplied search criteria. To search for files by name, run the following command:

$ find -name filename

This command will search for files with the specified name in the current directory and its subdirectories.

2. Find Files by Size

You can also search for files by size. To search for files larger than a certain size, use the following command:

$ find -size +size

This command will search for files larger than the specified size. To search for files smaller than a certain size, use the following command:

$ find -size -size

This command will search for files smaller than the specified size.

3. Find Files by Type

You can also search for files by type. To search for files of a certain type, use the following command:

$ find -type type

This command will search for files of the specified type. The type can be one of the following: f (regular file), d (directory), l (symbolic link), or b (block special file).

4. Find Files by Permissions

You can also search for files by permissions. To search for files with certain permissions, use the following command:

$ find -perm permissions

This command will search for files with the specified permissions. The permissions can be specified in octal notation (e.g. 0644) or symbolic notation (e.g. u=rwx,g=rx,o=rx).

5. Find Files by Owner

You can also search for files by owner. To search for files owned by a certain user, use the following command:

$ find -user username

This command will search for files owned by the specified user.

6. Find Files by Group

You can also search for files by group. To search for files owned by a certain group, use the following command:

$ find -group groupname

This command will search for files owned by the specified group.

7. Find Files by Access Time

You can also search for files by access time. To search for files accessed within a certain time period, use the following command:

$ find -atime time

This command will search for files accessed within the specified time period. The time period can be specified in days (e.g. -atime +7 will search for files accessed more than 7 days ago).

8. Find Files by Modification Time

You can also search for files by modification time. To search for files modified within a certain time period, use the following command:

$ find -mtime time

This command will search for files modified within the specified time period. The time period can be specified in days (e.g. -mtime +7 will search for files modified more than 7 days ago).

9. Find Files by Inode Number

You can also search for files by inode number. To search for files with a certain inode number, use the following command:

$ find -inum inode_number

This command will search for files with the specified inode number.

10. Find Files by Executing a Command

You can also search for files by executing a command. To search for files and execute a command on them, use the following command:

$ find -exec command {} \;

This command will search for files and execute the specified command on them. The command must be enclosed in quotes and the {} must be included to indicate the file name.

Conclusion

In this article, we have explained 35 practical examples of the Linux find command. We have shown how to search for files by name, size, type, permissions, owner, group, access time, modification time, and inode number. We have also shown how to execute a command on the files found. We hope you have found this article to be useful.
