Anyone have experience or suggestions on reasonable ways to print/dump the output of 'multiple commands being run in parallel' to the command line/ terminal? For example, mpop can download emails from multiple email accounts in parallel (it uses separate email UID files per account to isolate its download activity to a single email account), but how to actually do this in parallel -and- display the output of each command 'in real time' in a single terminal in a "reasonable" way? I've a little wrapper that retries up to MAX_TRIES=7 if an mpop account download has a TLS error (gmail pop3 dl producing a lot of these the last week or so...), and 7 retries * 5 lines of text per retry (retry header, date time stamp, echo of cmd being run, and finally the 2 mpop "TLS handshake failed" error lines) is a fair few lines of output... is it time to learn a 'full blown' TUI library? If so, is there such a thing usable from a shell script?
