> find . -i -name <regex> is NOT mentioned anywhere you've got some typos here, it's not mentioned because... that's not how find works. find has no -i like grep ; to ignorecase you use -iname ; and for name regular expression matching you need to use find . -iregex <regex> # (or -regex) find . -iname <pattern> # (uses wildcards ? \*) cheers :)
