# AWK

`hicream` requires the `awk` command to be installed on your system. If you are using a Unix-based system, `awk` is likely already installed. If you are using Windows a cywgin version of `awk` is searched for by the package. You can install `awk` by downloading the Gawk package from the GNU website: https://www.gnu.org/software/gawk/.
