I am a new to Linux/Unix programming and was learning form the tutorial: https://www.tutorialspoint.com/unix/unix-environment.htm
在本教程中,它说主目录中的.profile文件 初始化TERM变量并初始化PATH变量 到:$ PATH = / bin:/ usr / bin $
但是,当我打印.profile文件的内容时,会得到以下内容:
1 # ~/.profile: executed by the command interpreter for login shells.
2 # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
3 # exists.
4 # see /usr/share/doc/bash/examples/startup-files for examples.
5 # the files are located in the bash-doc package.
6 # the default umask is set in /etc/profile; for setting the umask
7 # for ssh logins, install and configure the libpam-umask package.
8 #umask 022
9 # if running bash
10 if [ -n "$BASH_VERSION" ]; then
11 # include .bashrc if it exists
12 if [ -f "$HOME/.bashrc" ]; then
13 . "$HOME/.bashrc"
14 fi
15 fi
16 # set PATH so it includes user's private bin directories
17 PATH="$HOME/bin:$HOME/.local/bin:$PATH"
我的问题是
(1)TERM变量未在任何地方初始化吗?
(2)PATH变量初始化为垃圾桶(?)-因为找不到名为“ HOME”的任何文件夹,所以路径 $ HOME / bin和$ HOME / .local / bin没有意义;还有哪个文件夹是$ PATH?
