Fix funcoeszz when using apple's sed

[jaysonsantos]

This software requires gnu-sed, so I've changed it to use explicitly gsed instead of apple's sed. With this you don't have to force users changing their paths to make gnu-sed default.

Can you elaborate on how it requires it to work? Also, can you file an issue upstream asking if they can support BSD sed? Thanks!

[jaysonsantos]

It fails when executing something like this set | sed -n '/^zz[a-z0-9]/ s/ *().*//p' but with gsed the same statement works set | gsed -n '/^zz[a-z0-9]/ s/ *().*//p'.

@jaysonsantos Can you give an example of how to run that? I'm not sure I totally understand from the comment. Thanks!

[jaysonsantos]

Install the current version on homebrew's master and run this:

export ZZPATH="/usr/local/opt/funcoeszz/funcoeszz.sh"
source "$ZZPATH"
zzzz

You will see the sed error.

I didn't get as far as zzzz using the system sh.

Current:

sh-3.2$ export ZZPATH="/usr/local/opt/funcoeszz/funcoeszz.sh"
sh-3.2$ source "$ZZPATH"
sh: /usr/local/opt/funcoeszz/funcoeszz.sh: line 1862: syntax error near unexpected token `('
sh: /usr/local/opt/funcoeszz/funcoeszz.sh: line 1862: `             paste -d"|" <(echo "$vartemp"|cut -f1 -d:|sed 's/^[[:space:]]\+//g;s/[[:space:]]\+$//g') <(echo "$vartemp"|cut -f2- -d:|sed 's/^[[:space:]]\+//g')|'

New:

sh-3.2$ source "$ZZPATH"
sh: /usr/local/opt/funcoeszz/funcoeszz.sh: line 1862: syntax error near unexpected token `('
sh: /usr/local/opt/funcoeszz/funcoeszz.sh: line 1862: `             paste -d"|" <(echo "$vartemp"|cut -f1 -d:|gsed 's/^[[:space:]]\+//g;s/[[:space:]]\+$//g') <(echo "$vartemp"|cut -f2- -d:|gsed 's/^[[:space:]]\+//g')|'

If I use a modern Bash, via Homebrew in this case, I get no errors at all with either BSD sed or GNU sed.

[MikeMcQuaid]

Looks like this needs a Requirement on a newer bash instead.

[DomT4]

CC @jaysonsantos. Can you switch to a recent bash and see if the sed error fails to reproduce for you as well? If it does, tweaking this PR to require Homebrew's bash would be great, and perhaps a small caveat warning of problems against the system sh. Thanks!
