Re: [Gimp-user] batch mode in gimp?

[Jehan Pagès <jehan marmottard gmail com>]

Hello,

You can do it this way. Tested by myself right now and working well:

$ gimp-2.9 -i -d -f -s -b "`cat script.scm` (simple-unsharp-mask
\"file.png\" 5.0 0.5 0)" -b '(gimp-quit 0)'

So basically you could have your small shell script call-gimp-function
with the following code inside:

------------------------------------------------------
#!/bin/sh

gimp-2.9 -i -d -f -s -b "`cat \"$1\"` $2" -b '(gimp-quit 0)'
------------------------------------------------------

Then you can call it this way:
$ ./call-gimp-function script.scm "(simple-unsharp-mask \"file.png\" 5.0 0.5 0)"

I think it should work well even if there are double quotes in the
definition script because I think cat escapes them before feeding the
contents to the main command.

Enjoy!

Jehan

P.S.: don't forget to replace gimp-2.9 in the script with your version
and to make your script executable.
