Execute shell script xubuntu
May 21st, 2009, 5:15pm  
Hi,
I was wondering if anyone had a solution for launching shell scripts from processing.
I'm trying open() but it doesnt seem to be working,
the shell script like this:
#
clear
echo "Printing"
lpr test.txt

in processing I do:
void mousePressed(){
open("./print");
}

but this does not seems to be working for me. Am I doing something wrong?
Thanks

Quoting from the open() reference page:
Quote:
The location parameter must be a full path name, or the name of an executable in the system's PATH.

You have no guarantee on the current working dir...

Hi,
thanks for the heads up!!
so I tried also what you are saying and actually it's launching the script!! but the problem is my sketch is opening it in a text editor instead of running it.
My script file is in chmod u+x and I also edited propeties of the file to be launched as an application.
This is way easier on osx with apple script...

does it need the usual shebang on the first line

#!/bin/bash

to tell it which interpreter to use

hi,
After the first post I added  #!/bin/bash it didn't change anything.
I'm thinking that this is a operating system problem...
I saw this on processing reference open()
"
On Linux, it first tries gnome-open, then kde-open, but if neither are available, it sends the command to the shell without any alterations.
"
I also tried doing something like this
void mousePressed(){
String[] params = {"lpr","test.txt"};
exec(params);
}
opens up a fresh terminal window but it doesnt run the command...

what am I missing here??

do you have gnome-open or kde-open?

i do (gnome-open) and it's displaying my script as text despite it being executable and having a .sh extension (oddly, .exe causes a different error)

even "gnome-open list.sh" opens it as text.

ok, i used nautilus to set that file to open using bash (right click, properties, Open With. add /bin/bash if necessary. associate the file (and possibly all .sh files) with this) and that's working now. gnome-open uses the nautilus mime-type settings. it's perhaps the wrong thing to use for bash scripts.

Hello koogy I tried what you said, now the double click seems to be working but I can't get it to work from processing. Could you be kind enough to test to launch a .sh file from your processing app??

Thanks...

i did test it like that and it worked, after i'd set it up using nautilus as specified

try
gnome-open file.sh
from the command line, get that working first
