I am needing to use app version in a .sh script on Mac osX 10.10 so that I can do a compare to another number so I can force an update or not.
So far I have this (I am using Firefox.app as an example)
FirefoxmdlsVersion= mdls -name kMDItemVersion /Applications/Firefox.app;
echo $FirefoxmdlsVersion
This returns kMDItemVersion = "34.0"
which is a step in the right direction but I need just the number so that I can do my compare example 340
Here is what I have attempted to do with a new variable but I dont get an error or output at all
FFV2=${FirefoxmdlsVersion//'kMDItemVersion ='}
FFV3=${FirefoxmdlsVersion:18:4}
I maybe going in the wrong direction here, but Ive looked a post and havent made any progress. Can anyone help me?
You could use tr
as well:
FirefoxmdlsVersion= mdls -name kMDItemVersion /Applications/Firefox.app | tr -d ".";
Which produces 3405
(From Firefox 34.0.5)
