groff: Invocation Examples
2.6 Invocation Examples
=======================
This section lists several common uses of 'groff' and the corresponding
command lines.
groff file
This command processes 'file' without a macro package or a preprocessor.
The output device is the default, 'ps', and the output is sent to
'stdout'.
groff -t -mandoc -Tascii file | less
This is basically what a call to the 'man' program does. 'gtroff'
processes the manual page 'file' with the 'mandoc' macro file (which in
turn either calls the 'man' or the 'mdoc' macro package), using the
'tbl' preprocessor and the ASCII output device. Finally, the 'less'
pager displays the result.
groff -X -m me file
Preview 'file' with 'gxditview', using the 'me' macro package. Since no
'-T' option is specified, use the default device ('ps'). Note that you
can either say '-m me' or '-me'; the latter is an anachronism from the
early days of Unix.(1) (⇒Invocation Examples-Footnote-1)
groff -man -rD1 -z file
Check 'file' with the 'man' macro package, forcing double-sided printing
- don't produce any output.
