2.4.1 Informational command line options

--arch

When given as the only option, it prints the architecture identifier (see Prolog flag arch) and exits. See also --dump-runtime-variables.

--dump-runtime-variables [=format]

When given as the only option, it prints a sequence of variable settings that can be used in shell scripts to deal with Prolog parameters. This feature is also used by swipl-ld (see section 12.5). Below is a typical example of using this feature.

eval `swipl --dump-runtime-variables`
cc -I$PLBASE/include -L$PLBASE/lib/$PLARCH ...

The option can be followed by =sh to dump in POSIX shell format (default) or =cmd to dump in MS-Windows cmd.exe compatible format.

--help

When given as the only option, it summarises the most important options.

--version

When given as the only option, it summarises the version and the architecture identifier.

--abi-version

Print a key (string) that represents the binary compatibility on a number of aspects. See section 2.22.
