This used to work fine, but then I installed an updated version of apache through brew and now this happens every time I switch back and forth. I used to be able to try and kill all of the apache processes or restart and that seemed to work. However now I can not get port 80 to free up. If I kill all processes running on port 80 apache will go away for a minute, but then return again.

So when I run

sudo lsof -i :80 | grep LISTEN
httpd   27987 root    4u  IPv6 0xcfcc888f0ccae989      0t0  TCP *:http (LISTEN)
httpd   27992 _www    4u  IPv6 0xcfcc888f0ccae989      0t0  TCP *:http (LISTEN)

These processes continue to return. I was trying to create an alias that I could use to kill the processes correctly as below. But I can not get this working in terminal.

alias stopall-port80="sudo kill -9 $(sudo lsof -i :80 | grep LISTEN | egrep -v 'PID' | awk '{print $2}' | sort -n | uniq)"

If I take just the section sudo lsof -i :80 | grep LISTEN | egrep -v 'PID' | awk '{print $2}' | sort -n | uniq sudo lsof -i :80 | grep LISTEN | egrep -v 'PID' | awk '{print $2}' | sort -n | uniq sudo lsof -i :80 | grep LISTEN | egrep -v 'PID' | awk '{print $2}' | sort -n | uniq and put it in the terminal it produces the correct PID's as expected. However when I try to run the alias stopall-port80 I get bash: 27057: command not found .

UPDATE

This is working instead of using the alias

stopall_port80() {
    sudo kill -9 $(sudo lsof -i :80 | grep LISTEN | egrep -v 'PID' | awk '{print $2}' | sort -n | uniq);
}

Issue 1: Unwanted Apache Restarts

If the port frees up "for a minute" and then is in use again, you should tell the process supervision system that's starting the conflicting process to stop running that process . In the case of Apache httpd on MacOS, that looks like:

sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

---

Issue 2: Surprising alias expansion

Your original code was -- on account of the use of double quotes -- building the list of httpd processes at the time when your alias was defined , not at the time when your alias was executed . You could fix that by changing the quoting type, but the better answer is to use a function:

stopall_port80() { sudo kill $(...); }

...which will evaluate the $(...) when the function is run, not when it's set up in your .bashrc .

Issue 3: Detecting PIDs Using A Port On MacOS

sudo lsof -n -iTCP:80 | awk '/LISTEN/ { print $2 }'
