Description of issue

I've installed coreutils, latest version. However, I don't see the "read" command in /opt/homebrew/opt/coreutils/libexec/gnubin.
I am trying to execute bash script that uses read but it uses flags that are only available with GNU read. Am I missing something?

Relevant casks

[gromgit]

I've never heard of "GNU read", and there's no read binary even in Linux builds of GNU coreutils.

Are you thinking of the read bash builtin? If so, and your script runs fine in modern Linuxes but not on macOS, that's because Apple stopped updating system bash at v3.2 for license reasons. Try brew install bash to get the latest bash instead.

Sidenote: if your scripts start with #!/usr/bin/env bash, and your PATH is properly set up for Homebrew, then they should automatically run with Homebrew bash. If not, you'll have to adjust accordingly.
