如何让我的 PS1 bash 会话始终显示整个密码？

  • 772

相关.bashrc部分：

if [ "$color_prompt" = yes ]; then
    if [[ ${EUID} == 0 ]] ; then
        PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\h\[\033[01;34m\] \W \$\[\033[00m\] '
    else
        PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\] \[\033[01;34m\]\w \$\[\033[00m\] '
    fi
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

问题是，我如何使它不缩短pwd主目录中的 if ，从而pwd在 PS1 中始终显示整体。

    通过替换\w并\W在PS1with中解决$PWD：

    if [ "$color_prompt" = yes ]; then
    if [[ ${EUID} == 0 ]] ; then
        PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\h\[\033[01;34m\] $PWD \$\[\033[00m\] '
    else
        PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\] \[\033[01;34m\]$PWD \$\[\033[00m\] '
    fi
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h $PWD \$ '
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="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h \$PWD\a\]$PS1"
    ;;
*)
    ;;
esac
