70 # A `ls -l' line looks as follows on OS/2.
71 # drwxrwx--- 0 Aug 11 2001 foo
72 # This differs from Unix, which adds ownership information.
73 # drwxrwx--- 2 root root 4096 Aug 11 2001 foo
75 # To find the date, we split the line on spaces and iterate on words
76 # until we find a month. This cannot work with files whose owner is a
77 # user named `Jan', or `Feb', etc. However, it's unlikely that `/'
78 # will be owned by a user whose name is a month. So we first look at
79 # the extended ls output of the root directory to decide how many
80 # words should be skipped to get the date.
82 # On HPUX /bin/sh, "set" interprets "-rw-r--r--" as options, so the "x" below.
85 # Find which argument is the month.
91 # Add another shift to the command.
