You can use "export name=value" to change environment variables, to show them, use "echo name". Especially, you can use "export $PE=style" to change the prompt style. And the style supports 3 special characters: \u current user \w current working directory \h host name of the computer For example, when setting: $ export $PE=\u@\h:\w> you will get a prompt like this: [email protected]:/Users/can/github/myShell> 2.

For example, $ ./test/while1 & But "&" can not appear in the middle of a command line, like: $ ls & -a -l You should change this to: $ ls -a -l & 3.
