This is a simplistic way to compare version numbers. This is useful for when commands change over time, and you do not know which or what kind of host will have which version of something.
echo -e "2.22\n11.3.4" | sort -V 2.22 11.3.4
printf '%s\n2.15\n' $(ldd --version | sed -n '1s/.* //p') | sort -V | head -n 1
printf '%s\n2.22\n' $(git --version | sed -n '1s/.* //p') | sort -V
Example:
if [[ $(printf '%s\n2.22\n' $(git --version | sed -n '1s/.* //p') | sort -V) != "2.22" ]]; then echo "Earlier version than cutoff" someCommand else echo "Later version of cutoff" someCommand_with_different_args fi
