Issue
grep -w uses punctuations and whitespaces as delimiters.
How can I set grep to only use whitespaces as a delimiter for a word?

Solution
If you want to match just spaces: grep -w foo is the same as grep " foo ". If you also want to match line endings or tabs you can start doing things like: grep '\(^\| \)foo\($\| \)', but you're probably better off with perl -ne 'print if /\sfoo\s/'
