Show output for n commands in parallel
Clash Royale CLAN TAG#URR8PPP
Is there a shell command to show the output of n given commands in parallel? I have n log-view commands (where n can be different at the startup time) and I like to show their output in parallel.
It should look like the split view of tmux
, but with tmux
it seems to be really hard to just give n commands and get a uniform split output view of them.
The call should be something like (the given commands are probably useless; they are just an example):split_command_view "watch -n0.1 ls -la" "tail -F log.txt" "date"
In this case the screen should be split in three sub-terminals and show the commands outputs.
Does something like this exist?
Thank you

multitail
is such a command:
multitail -l cmd1 -l cmd2
Or if you want the windows to persist after the commands have finished:
multitail -l 'cmd1; sleep inf' -l 'cmd2; sleep inf'
(if your sleep
doesn't support inf
, you can change it to a very large integer instead).

tail
supports displaying mutiple files at once, however it doesn't split the terminal into panes like tmux
does.
tail -f /var/log/syslog /var/log/auth.log
I usekubectl
to show the log of a remote cluster, therefore I think, I cannot usetail
.

To know the name of your current tty just type tty
. It will give you for example /dev/pts/0
. Then you can run commands like
tail -f /permanent.log > /dev/pts/0 &
With the &
at the end you send the proc to the background so you can run more commands. To recover the proc, you can use the jobs
and fg
commands.
