On: An Opinionated Guide to Xargs

Redirection like this doesn't seem to work if it comes first on GNU bash 5.0.17(1)-release.

For documentation purposes, this is the exact thing I tried to run:

    $ < <(echo hi) while read a; do echo "got $a"; done
    -bash: syntax error near unexpected token `do'

    $ while read a; do echo "got $a"; done < <(echo hi)
    got hi

Maybe there is another way...

One way which isn't great, but an option nonetheless… The zsh parser is happy with that form:

    $ zsh -c '< <(echo hi) while read a; do echo "got $a"; done'
    got hi

My position isn't that it is a good reason to switch shells, but if you're using it anyway then it is an option.

I’ve always preferred zsh and, as I’ve slowly adopted nix, I’ve slowly stopped writing bash in favor of zsh
