Here's one of Roland's old proposals:
RFE: Extend ksh93's printf %q to accept a modifier which defines the
quoting mode. Supported modes should be:
%(kshliteral)q same as existing %q
%(shliteral)q quote string with '\' (including spaces) that a POSIX
shell (and even the old bourne shell) can accept it
%(xml)q convert string into an xml literal (same as %H)
%(egrep)q convert string into a literal accepted plainly by egrep
(e.g. things like '[', ']', '(', ')' etc. are quoted)
%(grep)q convert string into a literal accepted plainly by grep (e.g.
things like '[', ']', etc. are quoted)
%(agrep)q, %(xgrep)q convert string into a literal accepted plainly by
grep -X/-A (e.g. things like '[', ']', '(', ')' etc. are quoted)
%(urlencode)q convert string into a literal accepted plainly as URL
(e.g. space gets encoded as '+', '!' as '%21', '*' as '%2A' etc.)
The modifers scheme will allow future extensions easily.
Comments welcome, I can try to make the patches if David and Glenn
like the idea.
