What Others Think

(in bash and zsh) You can negate character classes so that you don't have to list out all alphanumerics: rm -rf [^c]* c[^a]* but for longer prefix names you could write out the longer command "rm -rf [^c]* c[^a]* ca[^t]*, or just use a glob/regex in find: find . -maxdepth 1 -type f -not -name "ca*" -delete
