Question

出于某种原因，当我在Windows中启动Ubuntu终端时，在我键入bash之前它不会显示颜色。可能是什么原因，我该如何解决？当我安装WSL时，它总是显示颜色。

Answer 1

原因可能是修改后的bash_profile文件。尝试将这些行添加到〜/ .bash_profile

source ~/.bashrc

或从终端运行命令

echo "source ~/.bashrc" >> ~/.bash_profile

Answer 2

I ran into this forum hoping to find the solution to my problem. I eventually figured it out so here's how I fixed it:

Open up your terminal window by pressing Ctl + r, typing bash and pressing enter.
Make sure you're in your home directory by executing cd ~
Open up the bashrc file by executing nano .bashrc

Delete everything in that file and replace it with this:

# ~/.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\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_prompt force_color_prompt

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
fi

# colored GCC warnings and errors
#export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01'

# some more ls aliases
alias ll='ls -alF'
alias la='ls -A'
alias l='ls -CF'

# Add an "alert" alias for long running commands.  Use like so:
#   sleep 10; alert
alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
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

Save the file with Ctl + o
Reload the terminal. Try executing . .bashrc if it doesn't work. (notice the space between the two periods in that last command).

I don't know if the original poster will get this, but hopefully it will help a poor soul who stumbles upon it.

我最近遇到了同样的问题;我的想法是MS更新了快捷方式，它以某种方式默认为没有颜色？我想我可能会记录是否有人偶然发现了这篇文章。

如果打开开始菜单，向下滚动到＆＃34; Ubuntu＆＃34;，现在应该有两个项目：Ubuntu（带有完整的橙色图标）和Ubuntu终端（带有圆形规范徽标）。打开Ubuntu提供标准的彩色终端，而打开Ubuntu终端则提供纯灰色终端。

要修复，请更改快捷方式（之后应该没问题），或尝试wsltty：

wsltty - 它看起来很花哨，似乎支持在默认终端窗口上更好的复制/粘贴 - 可能是一个更好的选择

Answer 4

在您的.bashrc中，尝试取消注释以下行以强制使用颜色：

#force_color_prompt=yes

Answer 5

另一种更改颜色的简单方法是右键单击控制台栏并选择属性。

我设法更改了一些颜色，但有一种我无法修改，因为我不知道它实际指的是什么。我说的是“当前目录”的蓝色..

Answer 6

您运行的 shell 可能与 bash 不同。其中一些看起来相同。我当前安装的 WSL Ubuntu 出于某种原因从 sh 开始。我就是这样解决的。

可以通过做检查

echo $SHELL

如果是 /bin/bash 以外的任何其他内容，如果您的 shell 在提示中显示您的用户名，您可以通过从 @ 之前获取您的用户名来更改它，在我的情况下是 cjohnson 并发出命令：sudo usermod -s /bin /bash cjohnson

如果您当前的 shell 没有在提示中列出您的用户名，您可以使用命令：whoami

-s flash 告诉 usermod 为最后列出的用户修改 shell。

然后当你打开一个新的 shell 时应该得到正常的 bash shell。

因为没有选择答案。认为这是离开它的最佳位置，因为这是我对此问题的第一个搜索结果。未显示 WSL 终端颜色。

我的WSL终端失去了颜色
