It's coming from dlsrawhelper:
awk - =ITODORO\..* // { if ($2 ~ "^"regexpattern"$") { print $1 " " $2 " " $3 }; }

The . above should be double escape \\. See https://stackoverflow.com/questions/67111174/attempting-to-pass-an-escape-char-to-awk-as-a-variable . I think /bin/awk just doesn't complain about it.

FYI @AnthonyGiorgio

Any additional documentation needed?
Is it feasible for this port to not use an awk link or during the install, ask if a link should be used?
thanks

[IgorTodorovskiIBM]

Interesting, brew has this caveat:

GNU "awk" has been installed as "gawk".
If you need to use it as "awk", you can add a "gnubin" directory
to your PATH from your ~/.bashrc and/or ~/.zshrc like:

     PATH="$HOMEBREW_PREFIX/opt/gawk/libexec/gnubin:$PATH"

We could do something similar

[AnthonyGiorgio]

Could we also do gmake for GNU make?

[gngrossi]

If I remove the link, we can use awk and gawk independently.
Thoughts?

bash-5.2$ which awk
/hewitt/zopentools/zopen_repo/usr/local/bin/awk

bash-5.2$ cd /hewitt/zopentools/zopen_repo/usr/local/bin/
lrwxrwxrwx 1 @02858 @ISCICS1 4 Jan 4 17:07 awk -> gawk

[AnthonyGiorgio]

I'm in favor, as it means that I won't have to immediately change ZOAU to work with gawk.

[IgorTodorovskiIBM]

Some of the tool builds rely on the gawk version of awk. I'm ok to delete it from bin/, but I'd also like provide the symlink'd awk in another directory like gnubin for example.

We can probably do the same for gmake and potentially any other tools that collide with the native /bin tools.

I'll add this as a topic for the next dev meeting

[AnthonyGiorgio]

That would be a good compromise.

[gngrossi]

For now, removing the link.
Should this issue be closed?
thanks

[gngrossi]

Installed the upgrade and removed the two awk links.

[gngrossi]

Installed the upgrade and removed the gawk link from /hewitt/zopentools/zopen_repo/usr/local/altbin
Hopefully it can be used with ZOAU.
