The problem is that dash and other shells expand escape sequences by default on the 'echo' built-in while bash and others don't. The solution is printf. Hope that explains it. This should work no matter whether bash or dash is used as /bin/sh: printf '#!/bin/sh\njava -jar /usr/share/java/%s\n' "`/bin/ls build/jar`" > \ Cheers, -- Raphael Geissert - Debian Developer www.debian.org - get.debian.net -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
