Run hal Script

How do I execute a list of hal commands in a script ?

Whether I run Halrun and then a script of straight from My desktop, it dose't matter.


EG

Loadrt siggen
Loadusr Halmeter
SetP siggen.0.amplitude 4

etc

unless I'm missing something,

put all your command in a .hal file
then at command line run:
halrun myfile.hal

Thats what the halrun man page makes it seem like.

Sorry to reword the question, to run a script and leave the halrun window open after the hal commands are run.

halrun myfile.hal works but then it closes the HalRun environment.

What I'm trying to do is to go into Halrun and set a known environment by executing a list of commands that I have tested and are working and then test a few more manual connections/entries.

Thanks

(ref emc2.5.x)

1) If hal (or linuxcnc is already running):
$ halcmd -kf filename # source filename, then exit
$ halcmd -kf # interactive halcmd

When interactive in halcmd, you can "source" a file
and remain interactive, example:
$ cat t.hal
show pin
$ halcmd -kf
halcmd: source t.hal
...

2) If hal (and linuxcnc are not running) you can startup
the realtime system and hal:
$ halrun -kf filename # source filename, then exit
$ halrun -I -kf filename # source filename, then interactive halcmd
$ halrun -T -kf filename # source filename, then interactive haltcl


for more info:
$ man halrun
$ man haltcl

some experimentation is useful to understand the options
