ERTS Reference Manualerl (Command)-noinput Ensures that the Erlang system never tries to read any input. Implies-noshell.-noshell Starts an Erlang system with no shell at all. This flag makes it possible to havethe Erlang system as a component in a series of UNIX pipes.-nostick Disables the sticky directory facility of the code server. See code(3).-oldshell Invokes the old Erlang shell from Erlang release 3.3. The old shell can still beused.-pa Directories Adds the directories Directories to the head of the search path of thecode server, as if code:add pathsa/1 was called. See code(3).-pz Directories Adds the directories Directories to the end of the search path of thecode server, as if code:add pathsa/1 was called. See code(3).-s Mod [Fun [Args ]] Passes the -s flag to the init:boot() routine. See init(3).-setcookie Cookie Sets the magic cookie of the current node to Cookie. Aserlang:set cookie(node(),Cookie) is used, all other nodes will also be assumedto have their cookies set to Cookie. In this way, several nodes can share one magiccookie. Erlang magic cookies are explained in auth(3).-sname Name This is the same as the -name flag, with the exception that the host nameportion of the node name will not be fully qualified. The following command isused do start Erlang at the host with the name gin.eua.ericsson.se% erl -sname klackeEshell V4.7 (abort with ^G)(klacke@gin)1>Only the host name portion of the node name will be relevant. This is sometimesthe only way to run distributed Erlang if the DNS (Domain Name System) is notrunning. There can be no communication between systems running with the-sname flag and those running with the -name flag, as node names must be uniquein distributed Erlang systems.-version Makes the system print out its version number.-x Invokes the Erlang Support System xerl.All these flags are processed during the start-up of the Erlang kernel servers and beforeany user processes are started. All flags are passed to init:boot(Args). See init(3). Alladditional flags () passed to the script will be passed to init:boot aswell, and they can be accessed using the init module.System FlagsThe erl script invokes the code for the Erlang virtual machine. This program supportsthe following flags:-B De-activates the break handler for ^C and^\ .-h size Sets the default heap size of processes to the size size.-l Displays info while loading code.Erlang Run-Time System Application (ERTS)11
erl (Command)ERTS Reference Manual-P Number Sets the total number of processes for this system. The Number must begreater than 15 and less than 32769.-s size Sets the default stack size for Erlang processes to the size size.-v Verbose-V Prints the version of Erlang at start-up.The erl script must be changed to set or change these flags. They can also be setdirectly with the special flag +. For example:% erl -name foo +B +lIn this example, a distributed node is started with the break handler turned off and a lotof info is displayed while the code is loading.NotesThe special flag -- is used to end the system flags. The following example is typical forstarting a system:jam47 -- -s mod1 -s mod2 ........Note:It is not recommendable to run the code for the Erlang virtual machine directly, orset any of the flags for it with the special + flag. It should be used with care.See Alsoinit(3), erl prim loader(3), erl boot server(3), code(3), application(3), heart(3),net kernel(3), auth(3), make(3), epmd(1)12 Erlang Run-Time System Application (ERTS)
