Hi all,
i spend some time to write this Code for playing some around with Tinycore, with this Code it's possible to find the all dependencies, (the location of the extension must be in the tinycore default path), of a given extension like "Bash" and it will print them out sorted as its need to mount in the right order or tinycore not support, unmount.
this Script will print out:
./f_find_dependencies_sorted.sh bashbash readline ncurses
As the output shows, bash needs "readline" and "ncurses", the last word is the first extention to mount, example: mount ncurses, then mount readline, then mount bash, to get bash working as example.
This script needs bash installed.

any suggestions are welcome
please use the second attachment, i dont know how to delete the first attachment, if an mod can do delete the first attachment, it would be nice
thx
