我要评论需要修改bashrc
~/.bashrc
先备份一份
cp .bashrc bashrc.backup
编辑bashrc
vim ~/.bashrc
可以看到bashrc内容为
# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
# if not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
# don't put duplicate lines or lines starting with space in the history.
# see bash(1) for more options
histcontrol=ignoreboth
# append to the history file, don't overwrite it
shopt -s histappend
# for setting history length see histsize and histfilesize in bash(1)
histsize=1000
histfilesize=2000
# check the window size after each command and, if necessary,
# update the values of lines and columns.
shopt -s checkwinsize
# if set, the pattern "**" used in a pathname expansion context will
# match all files and zero or more directories and subdirectories.
#shopt -s globstar
# make less more friendly for non-text input files, see lesspipe(1)
#[ -x /usr/bin/lesspipe ] && eval "$(shell=/bin/sh lesspipe)"
# 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, unless we know we "want" color)
case "$term" in
xterm-color|*-256color) color_prompt=yes;;
esac
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes
if [ -n "$force_color_prompt" ]; then
if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
# we have color support; assume it's compliant with ecma-48
# (iso/iec-6429). (lack of such support is extremely rare, and such
# a case would tend to support setf rather than setaf.)
color_prompt=yes
else
color_prompt=
fi
fi
if [ "$color_prompt" = yes ]; then
ps1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi别的都不用关心
找到这样一段代码
if [ "$color_prompt" = yes ]; then
ps1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
ps1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi将其中的\w改为\w，也就是把小写w改为大写w
改完后保存退出
执行
source .bashrc
可以看到终端路径不论cd了多少层目录，都只会显示最后的文件夹名称
