How to capture the output of a top command in a file in linux?

Question

I want to write the output of a specific \'top\' command to a file. I did some googling and find out that it can be done by using the following command.

top         


        

Answer 1

From the top command, we can see all the processes with their PID (Process ID). To print top output for only one process, use the following command:

$ top –p PID

To save top command of any process to a file, use the following command:

top -p $PROCESS_ID -b  > top.log

where > redirects standard output to a file.
