Just because I like GNU parallel:

    parallel -kj1 'f="{}"; [[ -f "${f/data/A}" ]] || echo $f' ::: *_data.csv

This is better relative to the `sed` solution as it handles the `0000` case well.

I didn't realize Zsh (and Bash) was capable of removing zero padding in that way.

Everybody has there own style, but I would prefer to print the missing file pattern and avoid loops.

If you have GNU parallel installed (works in bash)

     parallel -kj1 '! [[ -f "{}" ]] && echo {} || :' ::: $(jot -w %04d_A.csv - 1 501)

or if preferred

     parallel -kj1 '! [[ -f "{}" ]] && echo {} || :' ::: {0001..0500}_A.csv

Just for fun some bash:

    for k in $(seq -f %04.f 1 501); do 
        f="${k}_A.csv"
        ! [[ -f "$f" ]] && echo $f || :
    done

or more succinctly,

    for k in {0001..0501}_A.csv; do
        ! [[ -f "$f" ]] && echo $f || :
    done

and if you have GNU parallel installed:

    parallel -kj1 '! [[ -f "{}" ]] && echo {} || :' ::: {0001..0501}_A.csv

Gold had intrinsic value before electronics, but for basically the same reason: it's immutable.

The bitcoin blockchain is also immutable.

Github flavored markdown does do tables (in a manner that's almost equivalent to org): https://github.com/adam-p/markdown-here/wiki/Markdown-Cheats...
