linux - 为什么我的 bash shell 脚本会出现这个错误

Question

我一直在尝试向我的 bash shell 脚本添加一个选项，有人执行“-r”我向 git 服务器推送，但我收到以下错误

mirror.sh: line 8: conditional binary operator expected
mirror.sh: line 8: syntax error near `-e'
mirror.sh: line 8: `if [[ "$1" -e "-r" ]];then'

下面是我的 bash 脚本:

#!/bin/bash
cd /home/joe/Documents/sourcecode/mirror.git
git svn rebase

#
# if option -r then push to master
#
if [[ "$1" -e "-r" ]];then
    git push origin master
fi

Answer 1

尝试:

if [[ "$1"= "-r"]];then

或

if [[ "$1"== "-r"]];then
