The default path under Linux system is usually long, it seems very inconvenient, then is there any way to modify the length of the Linux default path hint? Let's learn how to modify the terminal prompt path length under Linux with Xiaobian.

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

Locate the text above and note the value of the environment variable for PS1,\\u Is the current user, \\h is the host name, \\w is to display the full path, \\W is to display a simple path, turn w into W!
