That's in zsh. Yeah, I guess there are shells where it won't work.

- rascul 4y agoI think it's a zshism. I can't seem to do it in dash either.
- cestith 4y agoI've since tried in two versions of Bash (3.2 and 5.1) and in five different varieties of ksh (oksh, mksh, ksh93, pdksh, GNU ksh). It does seem to be a zshism. All the others do the redirect into the destination, but only zsh provides the content of the redirect from source without some other command to read it. The zsh way seems more properly fitting with the philosophy of the Unix shell to me. It would be an uphill battle getting everyone else to change that behavior, though.
- rpigab 4y agoI've been using this for a long time now and I didn't know if what a zshism because it felt so simple to use and Unixy, TIL too, thanks!
