Find redhat numeric release?

MikeyCarter · 02-05-2014, 10:52 PM

I need to verify by script that someone is using RHEL 6+ I know I can look at the /etc/redhat-release but I need a number so I can do something like:

Code:

if [ $ver -lt 6 ] ; then
  ... do something ...
fi

/etc/redhat-release is text and if it's Fedora or Redhat or other the text can be greatly different.

Any one have an idea?

Maybe lsb_release -r.

Please post the content of /etc/redhat-release.

Code:

egrep '[0-9\.]{1,}' *-release -oh

Just one...

Code:

grep -iq "6." /etc/redhat-release
if [[ $? = '0' ]] ; then
echo "Found it"
else
echo "Not RH 6"
fi

Also:
$ver -lt 6 will not work as a comparison for "any version less than 6".
So we look for any thing starting with "6."

Officially, it's the release and version of the rpm that provides /etc/redhat-release.

Code:

ver=$(rpm -q --qf '%{RELEASE}.%{VERSION}' -f /etc/redhat-release)
Major=${ver%.*}
Minor=${ver#*.}
