Using mouse scroll with Multitail
Is there any way to use the mouse wheel, or the terminal window slide bar, to look through a `multitail` log? Ideally `multitail` would work almost exactly like `tail` (except with the obvious coloring).

Any hint?

Triggering Multitail to start tailing when 'string' arrives

I am using multitail to monitor a group of logs.
I have been seeking a solution in the multitail options to start tailing a log only after the arrival of a matched string. I see plenty of capability in multitail to use -e and/or -ev to include/exclude rows that match the regex criteria, but not so much using a "trigger" to start tailing.
I am currently targeting 4-6 logs, separate panes, not merged, where the criteria above would be applied to each log entry ( -i ).
I would appreciate thoughts on an approach.

multitail - custom config (multitail.conf) location
Is it possible to provide a custom location for `multitail.conf`, or are my only options `/etc/multiltail.conf` or `~/multitail.conf`?

I'd like to provide a specific config file that has regexes specific to our app defined, but I can't put this in the account's home directory, or /etc.
I care most about the colors, so if it's possible to reference those from a separate file, then that would work well too.

want to live monitor all log files in one vieuw
I like to view all log files live like `tail -n0 somelog.log` But then for literally all log files on the system (CentOS 7) Or an other way to do this is also nice. I want to output this to a web page eventually.

Apply multitail's filtering to many files passed via wildcard
[`multitail`][1] has a nice regex-based filtering mechanism that is described in the manpage and online manual. Both sources state that log lines matching a given regex can be excluded from output using the `-ev` switch: multitail -ev "ignorelinescontainingthis" /var/log/whatever.log -ev "alsoignore...
multitail has a nice regex-based filtering mechanism that is described in the manpage and online manual. Both sources state that log lines matching a given regex can be excluded from output using the -ev switch:
multitail -ev "ignorelinescontainingthis" /var/log/whatever.log -ev "alsoignorethis" /var/log/another.log
This does, however, not seem to work for filtering many log files that are passed using wildcards:
multitail -ev "thisdoesntwork" /var/log/myservice*.log
Is there a way to get this to work?
For analysis purposes, I tried the -ec switch (which highlights regex matches) and it turns out that the filter is only applied to the first file in the wildcard list, but none of the other ones.

helped me to multitail from a remote location.
But my problem is one step deeper:
I need to run "sudo su" before I can tail the files.
How can I change user to su before I tail the file with
multitail -l "ssh dev-04 tail -f /opt/app/app.log"

For a list of input text, I want to execute a repetitive command using each element from the list. In addition I also need to monitor the results of each of these commands in parallel. So I am looking for a solution to display the repetitive commands output in separate windows in a single terminal console; probably need a form of terminal multiplexer?
So far I have the following:
for i in
command1 find msgs/Poly; do echo command2 echo "$i" ; multitail -l 'command2 echo "$i"' ; done
which seems to open only one window at a time.

I'm currently filtering out unwanted lines when using multitail
$ multitail -ev "foo|bar" -kr 0 55 -f /var/log/syslog
The problem is, when I want to scroll back through the output, the only way I know of how to do this is using the b command. The problem is, b brings up a buffer window that has all of the original (unfiltered) lines in it. How do I scroll through the output without seeing the lines that I don't care about?

Error opening file ssh docdev-04 tail -f /opt/alfresco/share.log (No such file or directory)

I would guess that the problem is in the password request. But anyway I don't know how to make it work

How can I display \n as new lines in multitail?
I am using multitail to monitor logs while I program. I really like this tool. However, it is hard to use it to view object output in a php error log because new line characters `\n` are not processed. Does anyone know of a way to achieve this?

Assume a multitail call like the following:
multitail -s 2 -l "long-running-command" -l "short-running-command"
Now, I would like to have both windows remain open, even after they are finished. However, multitail will just close the "short-running-command"-window once it exits. Which makes it kinda useless for my use case.
I know there are workarounds like outputting to files and tailing those instead, but I wonder if there is a way to keep the windows open in multitail even after the process is finished, without creating new files.

How to combine many multitail parameters?

Does multitail follow the inode or the file name by default?
For `logrotate`d files one usually uses `tail -F` instead of `tail -f` to follow the log file contents.

For
logrotated files one usually uses tail -F instead of tail -f to follow the log file contents. Does multitail(1) automatically follow the name instead of the inode (which likely changes with the log rotation)?
I sifted through the documentation and also searched on the web, but wasn't able to come up with a conclusive answer.
----------
Thanks to the accepted answer I found that the man page does mention the option I wanted, but uses the term "descriptor" instead of "inode". So this question and the answer should be the glue for the next person researching the topic.
-f Follow the following filename, not the descriptor.
--follow-all
For all files after this switch: follow the following filename, not the descriptor.

How to highlight the whole log-line in color with multitail
I'm trying to use `multitail` to tail logs with color highlights. I defined a custom color scheme in multitail.conf, something like this: colorscheme:my-color cs_re:red:^\[E cs_re:yellow:^\[W cs_re:magenta:^\[D cs_re:green,,bold:All session(s) filled for.* What I want to achieve with each line: 1.

I'm trying to use
multitail to tail logs with color highlights. I defined a custom color scheme in multitail.conf, something like this:
colorscheme:my-color
cs_re:red:^\[E
cs_re:yellow:^\[W
cs_re:magenta:^\[D
cs_re:green,,bold:All session(s) filled for.*
What I want to achieve with each line:
1. Color **the whole log-line** Red if it starts with string '[E'
2. Color ................................ Yellow if it starts with string '[W'
3. Color ................................ Magenta if it starts with string '[D'
4. Color ................................ Green if the line contains the string 'All session(s) filled for'
Unfortunately, none of the above is happening for me. For the first 3, it does color correctly the substring (e.g. '[E', '[W', etc) but not the whole log-line. In the last case, it doesn't color at all.
I also want to color the whole line by matching the third character of a line, e.g. color it Blue if the third character is 'A', how should I do this reliably with multitail?
