If you need to sort out what is reporting to the /var/log/messages to array in case of Red Hat Enterprise Linux or Fedora, you need to do flowing manipulations:

1. read log;
2. get 5th column from the log, it’s daemon name;
3. get rid of all digits, so the daemons with different PIDs would be counted as one;

1. get rid of all ‘/’ and replace ‘[’ and ‘]’ with ‘\[’ and ‘\]’ to keep things both readable and usable for future scripting;

1. sort unique stuff.

in my case this gets look like:

cat /var/log/messages | awk '{ print $5 }'| sed 's/\[[0-9].*$//'|sed 's/\[/\\\[/g' | sed 's/\]/\\\]/g'| sed 's/://g' |sed 's/\///g' |sort -u``

the result is usable as array for example. My host’s result:

abrt-hook-ccpp
at-spi-bus-launcher
audit
avahi-daemon
blueman.desktop
blueman-mechanism
bluetoothd
chronyd
cinnamon-killer-daemon
cinnamon-session
com.redhat.imsettings

Not sure about ‘number’ setting, if interferes with the clipboard annoyingly, so I can turn them off.
