Regarding G-code execution was created by arun6060
Hi to all,
I am new to linuxcnc . i have installed linuxcnc 2.5.1 in 10.04 and executed the samples in the linuxcnc. now i have created one model which is drawn using qcad software and save in .dxf file format and using dxf to g-code converter i have generated the g-code and it is executing in the linuxcnc gui .
Now i want to load the G-code file through (halcmd:) prompt i want to control the stepper motor for cutting the model through command line not in the gui mode .how to do this ?
clear me to proceed further... thanks for repliers...

You can start and stop execution of a loaded G-code file, but not open or close a file.
You probably want linuxcnc.org/docs/html/man/man1/linuxcncrsh.1.html or possibly linuxcnc.org/docs/html/man/man1/axis-remote.1.html

I don't think you can do this with halcmd. Halcmd is the HAL command line, and works only with HAL pins.Now i want to load the G-code file through (halcmd:) prompt i want to control the stepper motor for cutting the model through command line not in the gui mode .how to do this ?.

Any other way to control stepper motor through command line without using gui.. Thanks for your reply ..
I heard that formerly linuxcnc (EMC2) was using the command line and after that only GUI was developed for easier use of EMC2 users. So, if this statement is correct then, anybody please give details about how to control of the external stepper motors, lathes, etc.. using command line?

There is a text-mode GUI ( linuxcnc.org/docs/html/gui/keystick.html )
With a suitable setup in HAL (which could be achieved either line-by-line with halcmd or from the halrun prompt, or by loading a HAL file with the "source" command) then you can move a stepper simply with
halcmd setp stepgen,0.position-cmd 1000
for example.

I haven't been involved long enough to know if this was ever true.I heard that formerly linuxcnc (EMC2) was using the command line and after that only GUI was developed for easier use of EMC2 users.

It rather depends on what you want to do.please give details about how to control of the external stepper motors, lathes, etc.. using command line?

AFAIK you heard incorrectly
There were many interfaces originally, but all of them GUI's, relying on calls to underlying library functions.
Most have been deprecated in favour of Axis, because of its more sophisticated plot rendering etc.
You can do quite a lot with the commands that Andy has outlined, but basically you are using remotely, not executing command line executables.
Underlying this is that Linuxcnc / Emc is a complete machine controller designed to run G Code on machines as described in the .ini file, via the interpreter.
A lot of it is inextricably linked.
If you just want to move a stepper motor, you can do this with an arduino and step generator.
If you want to feed lines one by one on the command line and refuse to use a GUI MDI interface for some reason, you can use axis-remote --mdi G00 X56 Y20 etc
or emcrsh as advised
