问题描述
我似乎无法通过shebang将bash脚本转换为可执行文件.我的代码看起来像
I can't seem to get bash scripts to turn into executable files via shebang. My code looks like
#!/bin/bash
echo "hello"
该文件位于名为 test.sh 的文件中.我正在尝试让它与命令一起运行
where this is in a file called test.sh. I'm trying to get it to run with the command
./test.sh
在命令行中，但我刚收到权限被拒绝的错误.当我将其更改为
in the command line but i just receive the error of permission denied. When i change it to
sudo ./test.sh
我只是找回了找不到命令.我可以通过以下命令将文件转换为可执行文件:
I just get back that command not found. I can turn the file into an executable via the command the the command line:
chmod +x test.sh
代码正确输出
hello
我已经尝试过命令
which bash
返回目录/bin/bash 的目录，并且我也将此路径导出到 .bashrc 中，但无济于事.任何想法将不胜感激谢谢！为了清楚起见，我正在运行Linux Mint.
which returned the directory /bin/bash and I've also exported this path in my .bashrc to no avail. Any ideas would be greatly appreciated thanks! I'm running Linux mint just for clarity.
推荐答案
chmod +x test.sh
设置可执行位正是需要的.脚本需要同时具有shebang行和可执行权限.否则，您必须使用bash test.sh显式调用Shell.可执行位允许您编写./test.sh.
Setting the executable bit is exactly what's needed. A script needs both a shebang line and executable permission to be run. Otherwise you have to invoke a shell explicitly with, say, bash test.sh. The executable bit lets you write ./test.sh.
