reg exp question


Should be a difference between '[[:space:]][[:space:]]*' and '[[:space:]]+' ?

I use them in bash with sed and grep.

They are the same, but sometimes you need to use the first syntax or even a space character ' ' instead of '[[:space:]]' if your sed/grep versions doesn't support such notation.
