Gawk installation location incorrect on MacOS

[tomjn]

Homebrew installs gawk to /usr/local/bin/gawk on MacOS, but the make file only works if it's installed to /usr/bin/gawk

I don't know how to fix it right now because there is a problem with portability in shebang:

So we can't use #!/usr/bin/env gawk -f instead.

I think Homebrew scripts should patch shdoc during the installation.

Oh I didn't use homebrew to install shdoc, I ran brew install gawk then followed the instructions to clone and sudo make install. Eitherway manually patching scripts in a package manager sounds like a recipe for disaster and technical debt.

Instead, a more portable solution might be to use a shell script e.g. something like this

#!/usr/bin/env sh

read -d '' scriptVariable << 'EOF'
BEGIN {
    print "start"
}
{
    print $0
}
END{
    print "hello"
}
EOF

gawk -f "$scriptVariable" ${inputfile}

This way the problem you mentioned is sidestepped completely
