今天登录通过XShell7来登录Ubuntu20.04(HP)的系统,结果提示:ll这个命令不能用了!

source .bashrc

之后ll也是可以用的!

这台电脑因为拿鸿蒙的系统,把/home下的文件搞乱了,删除了很多很多文件!

感觉是多删除了一个文件了!

找了一个神舟的电脑,使用比对软件Beyond Compare很容易知道把.profile错误删除了。拷贝一个过来就OK了!

.bash_profile

.profile

~/.bash_login

一般在这些文件里写入命令source .bashrc而不是直接source .bashrc

个人配置最好放在.bashrc里,还不是直接放到.profile里,毕竟每个人的.baashrc路径添加的乱七八糟的,都是自己的路径。

环境变量配置失败,会导致各种报错!!

目录中得同时存在两个文件,上面的文件任选择一个+.bashrc即可在你系统登录账户的时候,自动source .bashrc

.profile文件示例

$ cat .profile 

# ~/.profile: executed by the command interpreter for login shells.

# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login

# exists.

# see /usr/share/doc/bash/examples/startup-files for examples.

# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask

# for ssh logins, install and configure the libpam-umask package.

#umask 022

# if running bash

if [ -n "$BASH_VERSION" ]; then

    # include .bashrc if it exists

    if [ -f "$HOME/.bashrc" ]; then

    . "$HOME/.bashrc"

    fi

fi

# set PATH so it includes user's private bin if it exists

if [ -d "$HOME/bin" ] ; then

    PATH="$HOME/bin:$PATH"

fi

# set PATH so it includes user's private bin if it exists

if [ -d "$HOME/.local/bin" ] ; then

    PATH="$HOME/.local/bin:$PATH"

fi

更改默认启动sh

echo $SHELL

/bin/bash    # 不用修改

/bin/sh      # 需要修改,运行chsh

chsh         # 输入密码,然后输入/bin/bash

.bashrc示例
