Mac OS X & macOS names. As you can see from the list above, with the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats. Sample bash script to show how to parse the macOS version - osversion.sh.
os_version.sh
| #!/bin/bash |
| # use argument 1 as the version or get it from sw_vers |
| os_ver=${1-:$(sw_vers -productVersion)} |
| # string comparison |
| if [[ '$os_ver' 10.13.* ]];then |
| echo'macOS High Sierra' |
| elif [[ '$os_ver' 10.12.* ]];then |
| echo'macOS Sierra' |
| else |
| echo'(Mac) OS X something' |
| fi |
| # regular expression |
| if [[ '$os_ver'=~ 10.1[23].* ]];then |
| echo'It's one of the Sierras' |
| fi |
| # awk |
| echo'minor version with awk: '$(echo '$os_ver' awk -F. '{ print $2; }') |
| echo'patch version with awk: '$(echo '$os_ver' awk -F. '{ print $3; }') |
| # array |
| IFS='.'read -r -a ver <<<'$os_ver' |
| echo'minor version with array: ${ver[1]}' |
| echo'patch version with array: ${ver[2]}' |
| # numerical comparison |
| if [[ '${ver[1]}'-ge 9 ]];then |
| echo'somewhere in California' |
| elif [[ '${ver[1]}'-ge 2 ]];then |
| echo'officially a feline' |
| else |
| echo'secretly a feline' |
| fi |
| # get the build number: |
| build_ver=${2-:$(sw_vers -buildVersion)} |
| if [[ '${ver[1]}'-le 5 ]];then |
| build_number='${build_ver:3}' |
| else |
| build_number='${build_ver:4}' |
| fi |
| if [[ ${build_number: -1}'a' ]];then |
| build_number='${build_number:0:$((${#build_number}-1))}' |
| fi |
| echo'build number: $build_number' |

Looking at this piece: I needed to take into account the leading colon in os_ver. To do that I modified my if statement to this |
