For me this extension is not working with ash
I had to change it to bash.
Otherwise the error was:
./opkg_list_installed.sh: 38: [[: not found

One possible explanation :

Ah, I confirmed my ash is actually just a symlink to bash on my env (Synology).
Could you test with the updated one ?
Thank you for your comment.

Thank you for your comment.

The new version works with #!/bin/ash
Thanks....

Doesn't work with busybox either (which is common on a lot of devices)

@TTimo,
I don't use Entware on the embedded environment like DD-WRT, etc.
If you know some emulated environment (VM or docker image) using busybox, I could make this work.

I'm not sure which part of the script doesn't work with busybox, though.
Are there any missing external commands below?

  • cut
  • sed
  • id
  • egrep
    or
  • ash? (If ash is missing change the first line to #!/bin/sh)

Hi,
I wrote a small script to restore packages from installed_packages.txt

packages=$(cat installed_packages.txt)

for package in $packages
 do 
 #echo $package
 opkg install $package
 done
