修改 bash 的提示符
askubuntu.com原文
Currently it is:
michael@Castle2012-Ubuntu-laptop01:~/Dropnot/webs/rails_v3/linker/spec/controllers$
want to：michael:controllers$
To change it for the current terminal instance only
Just enter PS1='\u:\W\$ ' and press enter.
To change it "permanently"
In your ~/.bashrc, find the following section:
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
Remove the @\h, and replace the \w with an uppercase \W, so that it becomes:
if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u\[\033[00m\]:\[\033[01;34m\]\W\[\033[00m\]\$ '
else
PS1='${debian_chroot:+($debian_chroot)}\u:\W\$ '
fi
Save, exit, close terminal and start another to see the result.
