Good day everyone,

Base on the link

 https://octave.org/doc/v4.0.1/Executable-Octave-Programs.html#Executable-Octave-Programs,

we could run an executable octave program directly from Unix command line. It should run the program in octave and then exit, right?! It should be similar to the example as 

#! octave-interpreter-name -q -f # comment

for which we are replacing 'octave-interpreter-name'  by '/usr/local/bin/octave’ . However, it does not work, or even with 

$ octave --exec-path /home/flapo/src/pism-dev4/aew4/Ref_runs/m2.m

with m2.m as an executable file similar to

#! octave-interpreter-name -qf
# a sample Octave program
printf ("Hello, world!\n");

Basically, I intend to use a huge bash script, mainly in ‘awk’, with one line for executing an octave program, exit octave, and then continuing through the bash script, all automatically. Am I using the right command script or it should be something different? 

Thank you very much for your help…

Octave now starts with a GUI, and you need the CLI version. You can either use /bin/octave-cli or /bin/octave --no-gui

cat > m.m
#!/bin/octave-cli -qf
printf("Hello, world!\n");
address@hidden tmp]$ chmod +x m.m
address@hidden tmp]$ ./m.m
Hello, world!

Note that . is not in my PATH so I had to use explicit path.
