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.
