Hi Arun,

The entries in bracket correspond to the heading CMD.
For "ps -ef", it corresponds to the process that are running in the system.

Refer the following link for more details -

The items in square brackets means that the process is actually a kernel thread, such as softirq, events, etc. It's not a process you can run in userland, but runs in kernel-space.

Its actually swapped out process.

>>Programs swapped out to disk will be shown without command line arguments, and unless the c option is given, in brackets.
