Category set to misc Status changed from Open to Assigned Assignee set to usa (Usaku NAKAMURA) Usa, do you think adding such support is a good thing? ---------------------------------------- Bug #7143: system("ls && ls") should work in windows https://bugs.ruby-lang.org/issues/7143#change-31119 Author: rogerdpack (Roger Pack) Status: Assigned Priority: Normal Assignee: usa (Usaku NAKAMURA) Category: misc Target version: ruby -v: ruby 1.9.3p194 (2012-04-20) [i386-mingw32] Hello. Since windows "on the command line" supports &&, I believe this should work for ruby system commands. It appears this run both commands, as expected (the first one fails): using "||" works well: >> system("ffmpeg -i || ls") # ffmpeg -i fails using && >> system("ls && ls") ls: &&: No such file or directory ls: ls: No such file or directory => false Thanks. -roger- -- http://bugs.ruby-lang.org/
