First, sort by time:

Ascending order is the arrangement of data from low to high, and descending order is the arrangement of data from high to low

Ls in descending chronological order: ls-lt (most commonly used)

Ls in ascending chronological order: ls-lrt

View files by file modification time:

Plus-r is the reverse sort:

The command explains:

-t: sort by modification time. In fact, we can use the man ls command to see the use of the parameters with the ls command.-t sort by modification time,newest first sorts files by modification time. The default is the most recently modified first.

-r: reverse sort, reverse order

Example: ls-ltr: sort in reverse by modification time [that is, the latest modification time comes last]

Sort by file size:

Plus-h displays the file size with units:

The command explains:

Ls-lS is sorted from largest to smallest

Ls-Slr is sorted from small to large

Ls lSh | ls-lShr if you want to type in a "human-readable way", add a-h to indicate "--human-readable"

In this way, the unit is k or M, and it is easier to see the results clearly.
