    Usage: $0 <directory> [tabwidth]

This script outputs a table of file information from the contents of <directory> like:

time  type  perm  uid  size  mime      hash  path  target
4444  file  -rw-  0    1111  text/...  abcd  /x/f
5555  exec  -rwx  100  2222  app./x-.  a135  /x/e
5566  dir   drwx  100        inode/d.        /x/d
5577  sym   lrwx  0          inode/s.        /x/l  /x/ltarg
5599  bad   l...  101        inode/s.        /x/z  /x/btarg

Setting [tabwidth] modifies tab spacing for easier reading in the console
