In arguments that look like assignments, and in GNU-style long options, file names can be part of a larger word. You're right. I assume Korn simply didn't consider that use case. -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRUc...@case.eduhttp://tiswww.cwru.edu/~chet/
Process substitution as part of a word [was: Incorrect alias expansion ...]

Assuming tar is GNU tar, something like tar -c -f txt.tar --files-from=<( ls *.txt ) works fine on bash and zsh, but not on ksh93; the process substitution becomes a separate word and the command fails. This was reported as a bug to the abandoned AT ksh2020 development effort but never fixed there, and I've no clue how to fix it yet either. https://github.com/att/ast/issues/1487 https://github.com/ksh93/ksh/issues/215 -- || modernish -- harness the shell || https://github.com/modernish/modernish || || KornShell lives! || https://github.com/ksh93/ksh
