How to use regular expression in Linux to output number?
How do you output only the number of words in /usr/share/dict/words that begin with any letter, let's say j?
I was hoping to use egrep 'J*' /usr/share/dict/words, but does not work well.

If your words are one on each line, then your solution is very close.
grep -ci '^j' /usr/share/dict/words
The ^ symbol means "start of line". -i flag means case insensitive search, -c means only report the count.
