I don't have jq, to_entries, or any utility starting with map installed on my system so I can't reproduce your output. Nonetheless, the diagnostic output you showed us seems to have a couple of commas that don't match what was in the code you showed us.
If I was guessing at what might be wrong, the first thing I would try would be to run your script with the shell's -x and -v options enabled to get a trace of what it is doing. The second thing I would do would be to change the line in your script that is currently:
into:
so the export command is invoked with one operand instead of nine operands for the Element2 case when <space>s are included in the value you want to assign to that exported variable.
Does anyone know of a way to mimic the up arrow/down arrow type bash behavior within a shell script?
Say I have a scripted menu, and would like to be able to up arrow to bring up the last X number of lines of user input?
Thanks to anybody with a suggestion. :) (0 Replies)
