I am (re)writing my windows.tmux
for my frequently used byobu
sessions. Below is my precise requirement:
I would like to have a tab (or window?) with a root prompt. (On start, it waits for the sudo passwd). I would like the second one to be split horizontally. In the upper portion I want to monitor my /var/log/syslog
and in the lower one dmesg
. So far I am able to achieve by doing the following:
new-session -AD -s 'root' sudo su - ;
new-window -n log watch -n 1 tail -n 15 /var/log/syslog
split-window watch dmesg | tail -15;
However the problem (which is completely irrelevant to this thread) that there are lots of entries in my syslog
(almost 4/5 lines per second), which I would like to avoid while monitoring. So I would like to grep -v
on these lines. The combination of watch
, tail
and grep
can be achieved as per my need (thanks to steeldriver for his answer here.)
watch -n 1 'tail -n 15 /var/log/syslog | grep -v -E "pattern1|pattern2"'
Here begins the problem: If I include the following line in my window.tmux
new-window -n log watch -n 1 'tail -n 15 /var/log/syslog | grep -v -E "pattern1|pattern2"'
I get,
sh: 1: tail -n 15 /var/log/syslog | grep -v -E "pattern1|pattern2": not found
In fact the more general problem is if I encapsulate the command in quotes (whether single '
or double "
), I get the same error.
Output of byobu --version
is:
byobu version 5.116
tmux 2.3
I am using GNU bash, version 4.4.7(1)-release
on 17.04.
Thanks in advance -- Mike
I have not experimented with screen
. Is this achievable using screen
?
windows.tmux
. Thenew-window
(same withnew-session
,split-window
) command(s) oftmux
cannot escape the quotes.
