[most likely solved] OT: Do you know a Linux compatible shell app for iOS/iPadOS, to write scripts on an iPad and then to use those scripts with Xubuntu?

Hi,

while iSH [1] has got some shortcomings, I'm one of those users who
don't like using octal numbers. For me, this is comparable to the
overuse of bashisms. In connection with chmod I usually use ugoa+-rwx.
Bashisms are often helpful when working with the CLI, but they easily
make scripts unreadable. So this isn't a shortcoming for me.

IMO a real shortcoming is, that it doesn't provide tabs. Instead of
using tabs, it's possible to run several instances of iSH, but then you
have to struggle with the odd window management of iPadOS.

However, I wrote an ash script, made it executable with chmod, installed
bash and tested bashisms. It all works well. On the left side of the on-
screen keyboard's toolbar it provides a Tab-key (not need for my iPad's
keyboard, it has got a Tab-key), a Ctrl-key, an Escape-key and a 
joystick alike Arrows-key (those three keys are missing on the default
keyboard of my iPad). A down scaled and cropped screenshot in low JPEG
quality is attached.

I like the Alpine Linux v3.14 shell on the iPad Pro that much, that I
will install Alpin on one of my multi-boot desktop PCs.

Regards,
Ralf
