ps command shows processes inside ["process name"] , of them without square brackets. tried search man pages , not contain regarding output format.

an example output shown below:

root 2544 0.0 0.0 0 0 ? s< 10:39 0:00 [kvm-irqfd-clean]

root 2746 0.0 0.0 26276 2400 ? ss 10:39 0:00 /usr/sbin/sshd

root 2759 0.0 0.0 4272 2212 ? sls 10:39 0:00 /usr/sbin/watchdog
