I found a new SSH client that Has quickly become my go-to: Prompt 2 from Panic
I’ve tried about 3 or 4 other SSH clients on my iPad, but this one does the best job of copy/paste of terminal text, plus the clips feater is awsome. Clips are short commands that when selected are pasted into the window. I use them for routine shell commands, MySQL commands, etc,etc. Super time saver.
I also find it’s special character support to be a notch above. Things like nmon finally render properly.
If you spend any time SSHing into a Linux/Unix server you need to give this app a shot.
