eval $cmd &; echo $last_pidbut this really, really does not seem to want to work...
that wasn't my issue, actually I figured it out: the command I was trying to run was all in one string, I needed to
string split it an additional time.
Unfortumately this didn't solve what seems to be a much deeper problem of
Xorg absolutely not wanting to do what I'm trying to do here lol
having to use the
set cmd (echo original command here) $cmd &
pattern is a little awkward, but it works
$ string replace -r '(\w+)\s+(\w+)' '$2 $1 $$' 'left right' right left $ $ string replace -r '(\w+)\s+(\w+)' '\$2 \$1 $$' 'left right' right left $
string replacehas a superfluous round of unescaping in the replacement part so you'll have to double up the slashes one more time. There's no great way of fixing it so we've introduced a feature flag until we figure out how to detect it and warn about it.
$into "expand this" and
$. If it does too much unescaping that means you need more escaping. I do not believe this subtlety helps any in the explanation, so we've left it as "escaping".
If you also want the output, you can still use the
if set x (tmux ls | grep foo)
set doesn't set the status itself and simply passes on whatever the command substitution returned.
