OpenBSD's ls: `-T` option shows complete time information

nabbisen - Jul 9 '20 - - Dev Community

In OpenBSD, ls -l shows time information flexibly due to the last-modified years.

  1. Rows about the year in or before last year
    • Format = "date - year"
  2. Rows about this year
    • Format = "date - time"
$ ls -l $SOME_DIR/
total [...]

It's usually useful.
On the other hand, there is the way to get full time of all rows, that is adding -T option.

$ ls -lT $SOME_DIR/
total [...]

Besides, this -T option is similar with --full-time option in Linux but the latter has a different display format which shows nano seconds.
