Use the find command in Centos to find files based on system time

Source: Internet
Author: User

The find command has several options for searching files based on your system's timestamp. These timestamps include

Last modification time of mtime file content atime file was read or accessed time ctime file state change time

Mtime and atime are both easy to understand, while ctime requires more explanations. Inode maintains the metadata of each file. Therefore, if the metadata related to the file changes, the inode data also changes. This may be caused by a series of operations, including creating symbolic links to files, changing file permissions, or moving files. In these cases, the file content will not be read or modified, so mtime and atime will not change, but ctime will change.

These time options must be used together with a value of n, specified as-n, n or + n.

N * 24 + 1 indicates 1*24 + 24 hours away .. + 0 indicates 0*24 + 24 hours; 1 indicates the range from 1*24 + 24 to 24 .. 0 indicates 0*24 + 24 to 0 .. -1 indicates 0*24 + 24, or even the future time...

1. Current Time: 24 hours-current time (yesterday-Today)
# Find.-mtime 0
2. Current time 48 hours ago-current time 24 hours ago (the day before yesterday)
# Find.-mtime 1
3. The current time is 48 hours ago (2 days ago)
# Find.-mtime + 1
4. Current Time: 24 hours-current time (yesterday-Today)
# Find.-mtime-1
