Cannot execute bash script in redhat linux
提问by Spark
I write a simple shell script to clean log files in redhat:
我写了一个简单的 shell 脚本来清理 redhat 中的日志文件：
Filename: clean.sh
文件名：clean.sh
#!/bin/bash
rm -f *.log core.*
But when I typed clean or clean.sh, it always prompt
但是当我输入clean或clean.sh时，总是提示
-bash: clean: command not found
-bash: clean.sh: command not found
What's the problem?
有什么问题？

You probably don't have .(the current directory) in your $PATH(and that's a good thing; having .in your $PATHcan be dangerous.)
您可能没有.（当前目录）$PATH（这是一件好事；.在您的目录中$PATH可能很危险。）
Try this:
尝试这个：
./clean.sh
And if the script file's name is clean.shyou can't run it as just clean, with or without a directory. The file name is clean.sh, and that's how you need to execute it.
如果脚本文件的名称是，则无论有没有目录，clean.sh您都不能将其作为 运行clean。文件名是clean.sh，这就是您需要执行它的方式。
Or you can change the name from clean.shto just clean. Unix-like systems (that includes Linux) don't depend on file extensions the way Windows does.
或者您可以将名称从 更改clean.sh为 just clean。类 Unix 系统（包括 Linux）不像 Windows 那样依赖于文件扩展名。

problem 1: maybe the execute permission on clean.sh is not set. Do this:
问题一：可能是没有设置clean.sh的执行权限。做这个：
chmod +x ./clean.sh
problem 2: RH Linux does not include CWD on the path by default. So, when you are in the same directory as clean.sh, type:
问题二：RH Linux默认路径上不包含CWD。因此，当您在与 clean.sh 相同的目录中时，键入：
./clean.sh
That should execute it.
那应该执行它。
