I can not find file-release through command line on OS X El Capitan Version 10.11.6. On my virtual machine in Ubuntu I can do "ls /etc/*release" and it shows me two files with all needed information:
$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.0 (Maipo) $ cat /etc/os-release NAME="Red Hat Enterprise Linux Server" VERSION="7.0 (Maipo)" ID="rhel" ID_LIKE="fedora" VERSION_ID="7.0" PRETTY_NAME="Red Hat Enterprise Linux Server 7.0 (Maipo)"
No idea how to find the file with release information on Mac. Please give me a hint or a hint how to search it?
