zsh 条件语句帮助

Question

现在感觉有点傻：

为什么我的条件总是正确的？

我试过了

# 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" ]]
    do something
fi
if [[ ${whoa} -gt 0 ]]
    do something
fi

我错过了什么？

Answer 1

事实证明，我在 if 语句之后遗漏了“then”。

应该

if [[ "${whoa}" != "0" ]]
then
    do something
fi
