Killing Chrome OS on Chroot Startup #4552
-
|
When I'm in a chroot, I execute "ps ax -o sess,pgrp,pid,cmd | awk '$4 ~ //chrome$/ { print $3 }' | xargs $nodo kill" to kill chrome os processes to free up my memory usage. However, it gets annoying to do it manually everytime so I'm thinking to add it as a start-up command so it will be done automatically. But, I am worried that the command might execute too early so that it kills chrome processes during chroot startup making it corrupt or something. This may sound stupid but I just want to know if the chroot will start just fine if I auto start the chrome processes command because I don't want to lose my chroot lol Btw I am using Ubuntu Focal Fossa with Xfce. |

Pretty sure that's a typo. #!/bin/sh
echo "#\!/bin/sh" | \
tee kill-chrome.sh
echo "ps ax -o sess,pgrp,pid,cmd | \\
awk '\$4 ~ /chrome\$/ { print \$3 }' | \\
xargs \$nodo kill \\
exit" | \
tee -a kill-chrome.sh
mv kill-chrome.sh /bin/kill-chrome
cd /bin
sudo chmod a-w kill-chrome
sudo chmod u+w kill-chrome
sudo chmod +s kill-chrome
sudo chown root:root kill-chrome
exitThere's probably a better way of doing this, but I'm still kind of new to Linux, so this was something of a learning experience for me. If you want to make this a shell script, don't forget to make it executable with Hope this helps somewhat. |

Now I have to ask... That being said, I'm not really sure what you did with awk, so I'm not really sure what's going on. |

Then at the very possible least... I was asking an earnest question and you turn around an start spewing gall every which way. Ask yourself: re you here to answer people's questions -- or to lord over people that you have more answers than they do? Think about that very long and very hard. I think you'll find that your actions are somewhat inconsistent with what you want. Certainly with what you ought to want. Assume the worst in events -- but not in people. |

If you wanted to be safe you could create a
.shscript with the command you use to kill Chrome OS, this could be added to path to make it easy or you could make it run at startup with, let's say, a 10 second wait.
