I'd like to run a script (let's say myScript.sh) every time a yum update or yum install command is executed.

So if I run yum update someprogram then myScript.sh should be executed right after that. Is this possible?

Currently I could run a script if I put it in the ".spec" file when I build the rpm to install, but we have a lot of packages and I'd like to have this script run everytime any package gets updated. I thought about maybe using a cron job to run it every hour but that doesn't seem like a good idea.

  • See this answer on Yum post actions. You basically write a small actions file that matches specific packages, general actions, or both, and you point it to your script. Commented Oct 28, 2021 at 2:27

You can create bash function in .bashrc :

myyumfunction() {
    yum update $1
    myScript.sh
}

Bash functions that you define in your .bashrc are available within your shell. You can call your function like this: 

$ myyumfunction someprogram

    This covers the manual call to yum but not things like automatique updates or calls to yum via GUIs for example. +1 anyway because it's a simple and good solution. Commented Nov 20, 2015 at 17:12
  • Thanks @shcherbak! It would be difficult for me to try to get other people to use my custom function, but this isn't a bad idea! I might end up having to do this. Commented Nov 21, 2015 at 0:52
