Is this, then, the same as the bug I reported originally - that was later replaced by echo '\\':
BACKSLASH='\u' SQUARE='\u[]' echo $BACKSLASH echo $SQUARE gives \u u[] on ubuntu and \u[] everywhere else So it is the echo command on Ubuntu dash only? A work around would be to use printf in place of echo when using ubuntu? This would work reliably on other versions of sh? > Date: Fri, 14 May 2010 22:55:17 +0000 > From: jil...@stack.nl > To: edwardcrich...@hotmail.com > Subject: [Bug 259671] Re: dash parses backslashes in single quotes > > The issue is not with the single quotes, but with dash's echo builtin. > Apparently, the way they are compiled and configured by default on > Ubuntu, dash's echo builtin interprets backslash escape sequences while > bash's does not. > > According to POSIX, this interpretation is permitted; with the XSI > option (following traditional System V), it is required. > > Practically, the echo utility can only be used portably if both > backslashes and initial hyphens (which could be interpreted as options) > are omitted.
