After the merge you could run the program again?

So we could easily create
Graphic SFS
or Browser SFS
bundles?

If I understand you, output is just another SFS that could be merged with something else. The output name defaults as "merge.sfs" You can merge several at once, however.. (Note: set MERGE & FILES dir to wherever you have enough space).

nice little script. If you want to merge a ton of SFS files, there is another easy way to do it. Install the 'Edit SFS' script and then take all the SFS files you want, pop them open, drag'n'drop the files into one window and then build that window. Bingo... a dozen SFS files built into one. Smile
Now if only someone could create a GUI program, where you can just drag and drop however many SFS files you want and have it merge them all.. heh
Perhaps in V2 of your work? Razz

There is a gui Ecube and I wrote Fluppy. It's a roxapp based on edit-sfs.

(It needs xpupsay for the dialog).

jemimah...think it needs some work. Files shouldn't HAVE to be in /mnt/home to include. Dragging onto the icon should list them, not just open up the program. Shouldn't need a few gigs to merge a few SFS's; also It's failing to even combine 2 little test SFSs.
Code:

ERROR - unsquashfs failed to expand /initrd/mnt/dev_save/myfiles.sfs
It returned the following error message:


This should be something SIMPLE that works. I like the pooches for the wireless, but gets old for simple utilities.

Doesn't seem to work as cli.

Hi Q5sys,

The nice thing about scripts is that you can incorporate them anyway you like. For your request, all you need is to have items dragged to an icon listed to a file. Then simply run the list as arguments to the script above. Very simple, and fun to try for yourself.

BTW/ I don't know why you'd want to open SFS's and drag files, etc. A script does that for you.

Here's a simple icon click version.
USAGE: Drag sfs files to desktop icon. Click on icon to create merge.sfs in /mnt/home

Desktop Icon: merge-icon; Place on desktop

Code:

#/bin/sh

### Desktop Icon for rox-merge
## USAGE: Drag SFS files to icon; click on icon to create merge.sfs
##          Click to create merge.sfs in /mnt/home
 

if [ "$1" == "" ]; then
 
  if [ -f /tmp/list ]; then
      rox-merge 
     
yaf-splash -font "8x16" -outline 0 -margin 4  -fg black -text "merge.sfs in /mnt/home"
  fi
exit
fi
 
echo $@ >>/tmp/list 


rox-merge script (name "rox-merge" and place in PATH)
note: you can edit MERGE and FILES directories for more space or
to change output directory from /mnt/home (if not using pupsave, etc).


Code:

#!/bin/sh
 

 if [ -f /tmp/list ]; then

  MERGE="/tmp/merge"
   mkdir "$MERGE"

  FILES="/tmp/files"
     mkdir "$FILES"

   while read line; do 
   
        mount "$line" "$FILES" -o loop,ro
        cp -rp ${FILES}/* "$MERGE"
        umount "$FILES"
        sleep 1
    done </tmp/list

mksquashfs "$MERGE"  /mnt/home/merge.sfs

## cleanup
   rm -r "$MERGE"
   rm -r "$FILES"
   rm /tmp/list
fi
