I am asking because I think the "no such file or directory" error means that the mydiff script itself is not found, as opposed to anything inside the mydiff script. I also think the "'mydiff' returned 255" is an incorrect message, since I don't think mydiff was actually started. I'm leaving the rest of your quoted message just for ease of reference by others: i.e. the execution of "mydiff" fails. > > Note that running "mydiff" from the shell does not give an error. > The issue occurs only with "svn diff --diff-cmd mydiff". > > And if "mydiff" starts with "#!/bin/sh", then > "svn diff --diff-cmd mydiff" works fine. > > Note about the use of "/usr/bin/env": with the actual script, this is > actually "#!/usr/bin/env zsh" with the goal of using the same script > on various platforms (where zsh can be at various places). > > -- > Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> > 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> > Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon) Thanks, Nathan
