# 因为bash中分号(;)和换行是等价的，所以有下面两种风格，其他多行语句也是类似的 # 本人偏好风格1 # 风格1 if condition; then command elif condition; then command else command fi # 风格2 if condition then command elif condition then command else command fi

逻辑操作符
判断条件支持且（&&）或（||）非（!）

# not if [[ ! 'aa' == 'bb' ]]; then echo True fi # or if [[ 1 -eq 2 || 1 -eq 1 ]]; then echo True fi # and if [[ 1 -ne 2 && 1 -eq 1 ]]; then echo True fi
判断时引号使用（quote）
使用[和test时，变量引用注意加双引号，否则得不到正确的结果，[[则不需要。
