如何在 bash 提示中显示/隐藏当前工作目录？

Question

When I use Linux console it shows way to current directory "admin@servername:/home$" or not - just "$". How to turn on/ off this hint (way to directory)? Probably it should be changes in file.bashrc in PS1 = '\u@\h:\w$', but this value in PS1 allready. Here is code sample from.bashrc:

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

What exactly should be done to show/ hide way to current directory? Thankyou in advance.

You should look up Bash prompt special characters .

As you can see in the list, the current working directory is \w , and \a is the bell character, so just remove those.
