hi.. can't figure this out. it's basic.. how can i do a find of all files in underlying recursive dirs. also, how can i do a search/replace of txt in all files that match a certain extension.. ie, how do i find all files that end in 'int' in the underlying dirs... or, how do i replace "foo' with 'dog' in all underlying dirs that end in 'ddf'.. i can see that 'ls -R * can/should get me all underlying files... but... i can also see that find . -name "*.int" would work to find the files... but i'm not sure how to get the rest. -bruce bedouglas@xxxxxxxxxxxxx
