Sure, dash > is smaller than either, but efficiency isn't critical for > an application such as rebase. rebaseall (which is a wrapper around rebase) _cannot_ rebase an in-use .dll. Dash has fewer in-use dlls than bash. Therefore, dash is the (much) better choice for rebase. By the way, the Bourne shell is pretty much obsolete. On Solaris, /bin/sh is still the Bourne shell, but on every other system, /bin/sh aims to be POSIX-compatible (the historic Bourne shell does not comply with POSIX). And for portability reasons, you are better off writing a POSIX-compatible script that can use /bin/sh rather than requiring /bin/bash. I'm also entertaining the notion of following Debian's lead and switching /bin/sh to dash, since dash is noticeably faster than bash if your script is POSIX-conforming. Not very seriously yet, but it's not out of the question. > > I then ran "man dash" and found two places in the man page > that use the Unicode MATHEMATICAL LEFT/RIGHT ANGLE BRACKET > (U+27E8/27E9) symbols.
