Greetings

this is driving me nutz.

using 10.6, from the terminal

sed ' s/([\t]+)/[:]/g' tabfile > notabfile

trying to search and replace tabs from a file in bash. I can do it in perl, perl -pi -e 's/\t/:/g' filename but not with sed. Ive tried it from a simple cat tabfile | sed 's/\t/,/g' 

any assistance would be helpful.
