Standard GNU-style keyword options

Question

The book "The Art of UNIX Programming" by Eric Raymond has a section entitled "The -a to -z of command line options", in which he enumerates a "semantic standard" of what various single-letter flags are expected to mean.

For example -a usually means all, -d usually means debug and -f usually means file.

Is there anything similar for GNU-style keyword options, that is long multi-letter options preceded by two hythens ( -- )?

In particular, I was looking for the GNU-style equivalents of -f and -o with the meanings input file and output file respectively.

Would the former option be --file ? Would the latter option be --output ?

Answer 1

Mostly most of the GNU programmers uses --output or -o for output file.

In addition for the long parameters generally more detailed and description need parameters uses two hyphens.
