sed substitution conditional
on lines beginning with echo, globally substitute text with subtext:
ok, i got that. what i want to do is to wrap ^echo into a not! conditional:
wondering what the syntax would be to make it like that... i can exclude based on the first character:
but then lines beginning with en, etc., are also excluded. i would like to be able to exclude based on a pattern at the beginning of a line, not just a character. i've tried lostsa syntactical? combinations, nothing seems to work... thanks.
