Illegal argument '--help'. Usage: /usr/share/couchdb/erts-13.2.2.16/bin/erl_call [-[demqrsv]] [-c Cookie] [-h HiddenName] [-x ErlScript] [-a [Mod [Fun [Args]]]] [-timeout Secs] (-n Node | -sname Node | -name Node | -address [HOSTNAME:]PORT) where: -a apply(Mod,Fun,Args) (e.g -a 'erlang length [[a,b,c]]' -c cookie string; by default read from ~/.erlang.cookie -d direct Erlang output to ~/.erl_call.out. -e evaluate contents of standard input (e.g., echo "X=1,Y=2,{X,Y}."|/usr/share/couchdb/erts-13.2.2.16/bin/erl_call -e ...) -fetch_stdout execute the code, specified with the -a or -e option, in a new process that has a group leader that forwards all stdout (standard output) data so that it is printed to stdout of the /usr/share/couchdb/erts-13.2.2.16/bin/erl_call process. See the /usr/share/couchdb/erts-13.2.2.16/bin/erl_call man page for additional information. -h specify a name for the erl_call client node -m read and compile Erlang module from stdin -n name of Erlang node, same as -name -name name of Erlang node, expanded to a fully qualified -sname name of Erlang node, short form will be used -address [HOSTNAME:]PORT of Erlang node (the default hostname is the hostname of the local manchine) (e.g., /usr/share/couchdb/erts-13.2.2.16/bin/erl_call -address my_host:36303 ...) (cannot be combinated with -s, -n, -name and -sname) -no_result_term do not print the result term -timeout command timeout, in seconds -q halt the Erlang node (overrides the -s switch) -r use a random name for the erl_call client node -s start a new Erlang node if necessary -v verbose mode, i.e print some information on stderr -x use specified erl start script, default is erl
