如何在$ PATH变量中添加目录，以便可以在bash中运行脚本而无需输入整个文件路径？

Question

I want to run a bash script "hello.sh" from the command line using only the file name and extension. I added the directory where this file exists ("/Users/myusername/dev"), into the $PATH variable by editing the .bash_profile file. However, when I try to run the script, I get "command not found". I am working on MacOSX.

Here is my $PATH variable, verified from the Terminal app: “/Users/myusername/dev:/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin”

If I move the script into the /usr/local/bin folder, also in my $PATH, the script can be run by typing it directly. One thought I have is that there might be some user rights I need to set for the directory? Otherwise, did I not set the path correctly within $PATH?

Two possibilities:

• permissions seem less likely to be a problem, but you do have to have both read- and execute-permission on the /Users/myusername/dev directory (and its parent, etc.).
• .bash_profile is read for login-shells. You may have overlooked either sourcing the file, eg, . ~/.bash_profile . ~/.bash_profile or logging out/in.

To check typos, I use a script that shows my path in readable form (see link ).
