我无法在我的终端(Ubuntu 14.04 LTS)中启用提示颜色。
这是我的.bashrc
:
force_color_prompt=yes
export LANGUAGE='en_US.UTF-8 git'
export HISTCONTROL=ignoreboth
#export HISTSIZE=100000
#export HISTFILESIZE=100000
# Eternal bash history.
# ---------------------
# Undocumented feature which sets the size to "unlimited".
# http://stackoverflow.com/questions/9457233/unlimited-bash-history
export HISTFILESIZE=
export HISTSIZE=
export HISTTIMEFORMAT="[%F %T] "
# Change the file location because certain bash sessions truncate .bash_history file upon close.
# http://superuser.com/questions/575479/bash-history-truncated-to-500-lines-on-each-login
export HISTFILE=~/.bash_eternal_history
# Force prompt to write history after every command.

这将启用颜色,并且还将为某些输出(例如 make 和 ls 的输出)启用颜色。
# Commented out, don't overwrite xterm -T "title" -n "icontitle" by default.
# If this is an xterm set the title to user@host:dir

}
获取~/.bashrc
文件以应用更改:
. ~/.bashrc

我猜你没有为提示设置颜色。你可以使用以下语法执行此操作:
\e[x;ym $PS1 \e[m
\e[ : Start colour scheme.
x;y : Colour pair to use (x;y)
$PS1 : Your shell prompt variable.
\e[m : Stop colour scheme.
要设置红色提示,请输入以下命令:
export PS1="\e[0;31m[\u@\h \W]\$ \e[m "
将其添加到您的.bashrc
以使其永久存在。
以下是可用颜色的列表:
Colour Code
Black 0;30
Blue 0;34
Green 0;32
Cyan 0;36
Red 0;31
Purple 0;35
Brown 0;33
Blue 0;34
Green 0;32
Cyan 0;36
Red 0;31
Purple 0;35
Brown 0;33
