Something else I discovered was grep.
When I do a Code:
cat file | grep "searchterm"
using grep from the SDK (https://www.morphos-team.net/files/sdk-20260529.lha) , grep gives a standard input error and cat starts acting strange.
However if I use grep from here https://aminet.net/package/util/cli/grep-1.68
it works without any issue.
Not complaining here just noticing this behaviour.
