Recursively search for files using find command in Bash
The command line tool for navigating file hierarchies is the command in Linux find. It can be used to find and monitor folders and files.
It allows searching by name, creation date, modification date, owner, and permissions of files and folders.
It has the following syntax:
$ find [directory where to start searching] [-options] [name of file]
Options can have the following attributes:
| Serial number | Options | Target |
|---|---|---|
| 1 | -links N | It searches for some files that don't have the specified link. |
| 2 | -name | Searches for files with the specified name or pattern. |
| 3 | -newer [filename] | Searches for files created after the file name. |
| 4 | -perm | Search for all files with specific permissions. |
| 5 | Used to find and display the full path name of a file. | |
| 6 | -empty | It searches for empty files or directories. |
| 7 | -size +N/-N | Used to search for files of a specified size. If N is used as +N, it means the file size is greater than N; if it is used as -N, it means the file size is less than N. |
