Common command-line options

The following is a list of command-line options that I’ve noticed are in common usage. In bold are the uses that I believe must be the default.

• -f
  • force
  • file (either input or output )
  • “from” type (combined with -t as “to type”, e.g. -f svg -t png to convert form SVG to PNG)
• -h
  • help
  • hostname (perhaps prefer -H instead)
• -i
  • input file (combined with -o as “output file”)
  • interactive
  • ignore/exclude
• -o
  • output file (combined with -i as “input file”)
• -q
  • quiet (which silences stdout, but not stderr, because stderr is for all diagnostic output)
• -r
  • recursive
• -t
  • “to” type (combined with -f as “from type” e.g. -f svg -t png to convert form SVG to PNG)
• -v
  • version
  • verbose
