3.3 Command-Line Options

‘-d’, ‘--daemon’

Starts the FreeM environment daemon, exactly one of which must be running at all times in order for FreeM interpreter and fmadm processes to function.

‘-e’, ‘--environment’

Selects the environment to be used. If no environment is specified, DEFAULT is used.

‘-k’, ‘--nofork’

When used with ‘-d’ or ‘--daemon’, causes the FreeM environment daemon to run instead in the foreground. Useful for debugging.

‘-S’, ‘--shmsize’

When used with ‘-d’ or ‘--daemon’, specifies the number of bytes of shared memory FreeM will allocate for the LOCK table, job table, and IPC table. This will determine the maximum number of concurrent FreeM processes and LOCKs available in this environment.

‘-c’, ‘--config’

Specify a configuration file other than $PREFIX/etc/freem.conf.

‘-h’, ‘--help’

Display a help message showing valid FreeM options.

‘-i’, ‘--import’

Causes your UNIX environment variables to be imported into FreeM’s local symbol table.

‘-f’, ‘--filter’

Allows your M routines to be used as UNIX filters.

‘-n <namespace-name>’, ‘--namespace=<namespace-name>’

Selects the FreeM namespace to be entered on startup. Must be defined in ‘/etc/<environment>/freem.conf’.

‘-r <entryref>’, ‘--routine=<entryref>’

Causes <entryref> to be executed at load, instead of %SYSINIT.

‘--standard=<standard>’

Sets the default FreeM dialect to use for new routine buffers.

Valid values for <standard> are as follows:

M77

FREEM, EXTENDED

Please note that FreeM is not entirely standards-compliant, regardless of the value of <standard>.

‘-v’, ‘--version’
