What is the
-alhF flag in
ls? I can't find it in the man page.
-a, --all do not ignore entries starting with . -F, --classify append indicator (one of */=>@|) to entries -h, --human-readable with -l, print sizes in human readable format (e.g., 1K 234M 2G) -l use a long listing format
ls -alhF is equivalent to
ls -a -l -h -F
The ability to combine command line arguments like this is defined by POSIX.
Options that do not require arguments can be grouped after a hyphen, so, for example, -lst is equivalent to -t -l -s.
