我的Ubuntu 12.10之下，我已經安裝了這個混帳提示感知：https://github.com/jimeh/git-aware-prompt在Ubuntu下的Git分支提示不工作
每當我在其中有一個Git倉庫的目錄，我需要做的源~/.bash_profile顯示分支。如果我不這樣做，它不會顯示出來。但是，當我關閉終端並轉到同一個目錄時，我需要再次執行~/.bash_profile，爲什麼會發生這種情況？
我的問題是，在我的.bashrc已經定義PS1爲：
case "$TERM" in
xterm-color) color_prompt=yes;;
esac
# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes
if [ -n "$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)}\[\033[01;32m\]\[email protected]\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
PS1='${debian_chroot:+($debian_chroot)}\[email protected]\h:\w\$ '
fi
unset color_prompt force_color_prompt
# If this is an xterm set the title to [email protected]:dir
case "$TERM" in
xterm*|rxvt*)
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\[email protected]\h: \w\a\]$PS1"
;;
*)
;;
esac
這將覆蓋我在.bash_profile文件：
export GITAWAREPROMPT=~/.bash/git-aware-prompt
source $GITAWAREPROMPT/main.sh
export PS1="\[email protected]\h \w\[$txtcyn\]\$git_branch\[$txtylw\]\$git_dirty\[$txtrst\]\$ "
我怎樣才能將這些PS1的兩設置？
