[PATCH v2 1/8] git-prompt: use here-doc instead of here-string

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Avi Halachmi (:avih)" <avihpit@xxxxxxxxx>

Here-documend is standard, and works in all shells.

Both here-string and here-doc add final newline, which is important
in this case, because $output is without final newline, but we do
want "read" to succeed on the last line as well.

Shells which support here-string:
- bash, zsh, mksh, ksh93, yash (non-posix-mode).

shells which don't, and got fixed:
- ash-derivatives (dash, free/net bsd sh, busybox-ash).
- pdksh, openbsd sh.
- All Schily Bourne shell variants.
