Pause and continue Wi-Fi sniffing in Terminal using airport command I'm capturing packets on a specific channel using "airport" command on Mac OS X Sierra. The command saves the packets into a *.cap file in my tmp folder. The file is already almost 2 GB large.
What I would like to do is to pause the capturing process and then be able to continue to capture on the same channel and into the same *.cap file.
I'm afraid to just abort the command in Terminal using CTRL+C because then after rerunning the command I suspect it will just create another *.cap file and not continuing using the original one.

The exact command I ran is:

sudo airport sniff 12


Anyone can help please? Thanks in advance.
You can suspend a command in the bash shell using control-Z. To resume the command, run fg.
