我在哪里可以找到默认的/etc/bash.bashrc文件的内容?
我不小心覆盖了/etc/bash.bashrc
文件。
请告诉我要恢复的文件中的默认内容,或文件本身。
如果你覆盖了你的bash,最好的方法是从系统本身而不是其他人那里再次复制它:
rm ~/.bashrc cp /etc/skel/.bashrc ~/
我的/etc/bash.bashrc文件如下:
# System-wide .bashrc file for interactive bash(1) shells. # To enable the settings / commands in this file for login shells as well, # this file has to be sourced in /etc/profile. # If not running interactively, don't do anything [ -z "$PS1" ] && return # check the window size after each command and, if necessary, # update the values of LINES and COLUMNS. shopt -s checkwinsize # set variable identifying the chroot you work in (used in the prompt below) if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then debian_chroot=$(cat /etc/debian_chroot) fi # set a fancy prompt (non-color, overwrite the one in /etc/profile) PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' # Commented out, don't overwrite xterm -T "title" -n "icontitle" by default. # If this is an xterm set the title to user@host:dir #case "$TERM" in #xterm*|rxvt*) # PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"' # ;; #*) # ;; #esac # enable bash completion in interactive shells #if [ -f /etc/bash_completion ] && ! shopt -oq posix; then # . /etc/bash_completion #fi # sudo hint if [ ! -e "$HOME/.sudo_as_admin_successful" ]; then case " $(groups) " in *\ admin\ *) if [ -x /usr/bin/sudo ]; then cat <<-EOF To run a command as administrator (user "root"), use "sudo ". See "man sudo_root" for details. EOF fi esac fi # if the command-not-found package is installed, use it if [ -x /usr/lib/command-not-found -o -x /usr/share/command-not-found ]; then function command_not_found_handle { # check because cnf could've been removed in the meantime if [ -x /usr/lib/command-not-found ]; then /usr/bin/python /usr/lib/command-not-found -- $1 return $? elif [ -x /usr/share/command-not-found ]; then /usr/bin/python /usr/share/command-not-found -- $1 return $? else return 127 fi } fi
但是,您也可以从Live CD启动并将实时CD文件复制到硬盘上,即
sudo mkdir /mnt/tempmount sudo mount -t ext4 /dev/sda1 /mnt/tempmount sudo cp /etc/bash.bashrc /mnt/tempmount/etc/bash.bashrc
更改/ dev / sda1用于安装ubuntu的任何分区。
从Bash包中获取它
-
从http://packages.ubuntu.com/maverick/i386/bash/download下载Bash安装程序
- 如果你有一个较新的Ubuntu版本,你可以换掉“Maverick”作为你的版本名称。
-
使用Archive Manager浏览.deb文件
-
解压缩
/etc/bash.bashrc
- 你也可以在
/etc/skel/.bashrc
下找到~/.bashrc
。
- 你也可以在

将根.bashrc复制到我的文件夹对我来说是最简单的解决方案。
sudo cp /root/.bashrc ~
除了Braiam提供的信息之外 ,您还可以复制以下.bashrc文件的内容,如在如何恢复.bashrc文件中所述?
