Junio's "sq_quote()" works wonderfully on any valid shells. The fact that tcsh expands ! even inside single quotes is just pure braindamage. You could expand "sq_quote" to handle '!' and '\' characters the exact same way it handles the single tick (end single-tick quoting, do \! or \\ and start single-tick quoting again) and that might be good enough for tcsh. IOW, the string "a\b'c!d" would become 'a'\\'b'\''c'\!'d' after surrounding sq_quote with single-ticks. Insane? Linus
