zsh

Feeling kinda dumb right now:

Why is my contional always true?

I've tried

# this should let me know what's not a directory or 
# symbolic link.
whoa=`find ${MUSICDIR} ! -type l ! -type d | wc -l`

# I would expect if it's 0 (meaning nothing was found) that
# one of these statements would evaluate to false, but so far
# it's always evaluating to true
if [[ "${whoa}" != "0" ]]
if [[ ${whoa} -gt 0 ]]

What am I missing?

Is fish or zsh better for shell programming?

I'm a bash user willing to switch to a more friendly and advanced shell. I read a lot of good things about zsh, but I gave a quick test at fish and it seems great too. Both seem very close in term of features, what is your opinion about those two shells especially as regards shell programming? >>> More
