我一直在玩彩色提示,设置在.bashrc
。
问题是我总是需要寻找.bashrc
后登录时。当我登录时,我可以看到该文件的来源(我尝试在echo "SOURCED"
文件顶部添加一个。
然而,当我登录时,彩色提示的命令从未运行,尽管重新资源.bashrc
工作 - 颜色是在之后设置的source ~/.bashrc
,但我对这种行为的性质感到好奇。

答案1
您有.profile
或 吗.bash_profile
?
当 BASH 作为登录 shell 调用时,将执行以下脚本:
/etc/profile
~/.bash_profile
~/.bash_login
~/.profile
~/.profile
我要调用的内容如下.bashrc
:
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
