Re: [Gimp-user] gimp-user-list Digest, Vol 130, Issue 6

The concept of storage in Linux is a flat file space meaning a single
sequence of 1's and 0's which may be organized any which way for a defined
type standard. I was wondering how to open up any file as a binary so I
could 'visualize' it in GIMP or Audacity to help aid analysis of things
like heuristics or segmentations. I tried storing a different file as a
bitmap and opening it but it failed, any ideas?

Thank you for any help you can provide,

Carl

I'd also find an example interesting.

bash but the parameters to give in command line to run gimp procedures. I
don't understand very well what I must give for args in a gimp procedure.
This is why I asked for an example with a file-jpeg-load or

file-jpeg-save

procedure. I get some error messages that I don't understand. So my
question remains, what are parameters to give to these procedures? Could
someone write me this command line? So I will have an example that I

can't

find on the net. Thank you.

A problem you have is the multiple layers looking at your double quotes:
the shell interpreter that calls Gimp, and
the script-fu interpreter. Quotes are processed and not seen by Gimp and
script-fu.

Since you are on a Unix shell, try this:

        printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
"/home/user/ev.jpg" "/home/user/ev.jpg")" -b "(gimp-quit 0)"

This will print a line per "token" passed to the actual command:

gimp -i -b (file-jpeg-load RUN-NONINTERACTIVE /home/user/ev.jpg
/home/user/ev.jpg) -b (gimp-quit 0) As you can see, the quotes around the
file names have been removed. You have to either escape them:

printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
\"/home/user/ev.jpg\" \"/home/user/ev.jpg\")" -b "(gim p-quit 0)" gimp
-i -b (file-jpeg-load RUN-NONINTERACTIVE "/home/user/ev.jpg"
"/home/user/ev.jpg") -b (gimp-quit 0) Or use outer single quotes (but this
makes variable substitution in the shell a bit contrived:

printf "%s\n" gimp -i -b '(file-jpeg-load RUN-NONINTERACTIVE
"/home/user/ev.jpg" "/home/user/ev.jpg")' -b '(gimp-qu it 0)' gimp -i -b
(file-jpeg-load RUN-NONINTERACTIVE "/home/user/ev.jpg"
"/home/user/ev.jpg") -b (gimp-quit 0)
Or, if script-fu supports it (that's what I do for pythin-fu), outer
double qoutes and single quotes for the scrpit-fu strin

printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
'/home/user/ev.jpg' '/home/user/ev.jpg')" -b "(gimp-qu it 0)" gimp -i -b
(file-jpeg-load RUN-NONINTERACTIVE '/home/user/ev.jpg'
'/home/user/ev.jpg') -b (gimp-quit 0)

Ok, so some "clever" reformatting of my answer happened, so let's try
again. If this is still garbled, here is a screenshot of what I mean:
https://imgur.com/vBKHf1g

A problem you have is the multiple layers looking at your double quotes:
the shell interpreter that calls Gimp, and
the script-fu interpreter. Quotes are processed and not seen by Gimp and
script-fu.

Since you are on a Unix shell, try this:

 ??? printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
"/home/user/ev.jpg" "/home/user/ev.jpg")" -b "(gimp-quit 0)"

This will print a line per "token" passed to the actual command:

 ??? * gimp
 ??? * -i
 ??? * -b
 ??? * (file-jpeg-load RUN-NONINTERACTIVE /home/user/ev.jpg
/home/user/ev.jpg)
 ??? * -b
 ??? * (gimp-quit 0)

As you can see, the quotes around the file names have been removed. You
have to either escape them:

 ??? printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
\"/home/user/ev.jpg\" \"/home/user/ev.jpg\")" -b "(gimp-quit 0)"

 ??? * gimp
 ??? * -i
 ??? * -b
 ??? * (file-jpeg-load RUN-NONINTERACTIVE "/home/user/ev.jpg"
"/home/user/ev.jpg")
 ??? * -b
 ??? * (gimp-quit 0)

Or use outer single quotes (but this makes variable substitution in the
shell a bit contrived:

 ??? printf "%s\n" gimp -i -b '(file-jpeg-load RUN-NONINTERACTIVE
"/home/user/ev.jpg" "/home/user/ev.jpg")' -b '(gimp-quit 0)'

 ??? * gimp
 ??? * -i
 ??? * -b
 ??? * (file-jpeg-load RUN-NONINTERACTIVE "/home/user/ev.jpg"
"/home/user/ev.jpg")
 ??? * -b
 ??? * (gimp-quit 0)

Or, if script-fu supports it (that's what I do for pythin-fu), outer
double qoutes and inner single quotes for the scrpit-fu strings

 ??? printf "%s\n" gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE
'/home/user/ev.jpg' '/home/user/ev.jpg')" -b "(gimp-quit 0)"

 ??? * gimp
 ??? * -i
 ?? ?* -b
 ?? ?* (file-jpeg-load RUN-NONINTERACTIVE '/home/user/ev.jpg'
'/home/user/ev.jpg')
 ??? * -b
 ?? ?* (gimp-quit 0)

Ofnuts is correct that the problem is with the nested double quotes. The
inner ones that are before and after the file name need to be escaped.

gimp -i -b "(file-jpeg-load RUN-NONINTERACTIVE \"/home/user/ev.jpg\"
\"/home/user/ev.jpg\")" -b "(gimp-quit 0)"
