htop
How can I save the output of htop to a file? With top, I can run
top -b -n1 > top.txt
where -b specifies batch mode and -n specifies the number of iterations.
But the man page of htop doesn't offer such a possibility.
Is taking a screenshot the only way?
You can't anchor a given process line to the top but htop can follow a process if you press Shift+F. From the man page:
F "Follow" process: if the sort order causes the currently selected process to move in the list, make the selection bar follow it. This is useful for monitoring a process: this way, you can keep a process always visible on screen. When a movement key is used, "follow" loses effect.
Here I'm following my Firefox process:
Note that if you're only interested in one particular process, the -p <pid> will do what you want (12352 is the pid of Firefox on my system):
$ htop -p 12352
After executing sudo htop, just use the arrow keys to select the process you want to remove and then press either F9 or k then select which signal you want to send in the list (using the arrow keys) and press enter.
If you just to ask "politely" a process to quit use 3 SIGQUIT.
If you want to make sure the process quits use 9 SIGKILL.

Ron provided a link to htop output to human readable file and a quote from the top-voted answer by the developer of htop.
