use of #!/usr/bin/env octave with optargs ?

[Eric Chassande-Mottin]

hi,

I'd like to run a script with the following shebang line
#!/usr/bin/env octave -q

but I get an error
/usr/bin/env: octave -q: No such file or directory

an old thread says there are no solution
http://www.nabble.com/octave-shebang-td394305.html#a394305

just wondering if this is still the case.

cheers,
eric

I don't think a solution has been presented, and apparently it isn't  
trivial to produce one (see  
http://en.wikipedia.org/wiki/Shebang_(Unix)#Portability). Perhaps  
octave should ship a simple program 'octave-q' that acts just like  
'octave' when called with the '-q' argument?

Hmm, on the current Kubuntu, the following works for me:

1) create a script "octave" in ~/bin/octave that contains

#!/bin/sh
/usr/local/bin/octave -q

2) make it executable, and make sure that ~/bin/ is before
/usr/local/bin in $PATH

Good enough for government work, no?

You can write a shell script and put it somewhere:

=============== /usr/local/bin/envoctaveq ==================
#! /bin/sh
exec /usr/bin/env /usr/bin/octave -q "$@"
============================================================

then use this as your first line:
#! /usr/local/bin/envoctaveq

I see that you do not use the -f option to Octave.  If this is
intentional or an oversight?  Generally speaking, you want 'octave -qf'
for invoking a script.
