Find command

1. Time-related commands

-atime n: n is a number, meaning files that have been accessed (access) within a day before n days.

-ctime n: n is a number, meaning a file that has been modified (change) within one day before n days.

-mtime n: n is a number, meaning a file that has been modified (modification) within one day before n days.

-newer file: file is an existing file, meaning that as long as the file is newer than file, it will be listed.

two。 Parameters related to the user or user group name:

-uid n: n is a number, which is the user's account number ID, or UID, and the UID is recorded in / etc/passwd corresponding to the account name.

-gid n: n is a number, which is the ID of the user group name, or GID, and this GID is recorded in / etc/group.

3. Parameters related to file permissions and names:

-name filename: search for a file named filename

-size [+ -] SIZE: search for files larger (+) or smaller (-) than SIZE. The specifications of this SIZE are: C: for byte,k: for 1024bytes, so to find a file larger than 50KB, it is "- size + 50K"

-perm + mode: search for files whose file attribute "contains the attributes of any mode". For example, when we search for-rwxr-xr-x, that is,-perm + 755, but a file attribute of-rw- will also be listed because it has-rw.... The attribute of exists.
