Modify the command prompt line path length under Linux

The default path hint is the full path, so the line is long and may take up the full width, looking very uncomfortable! Just like this.

[Email protected]:~/trunk-new/build_dir/target-mips_34kc_uclibc-0.9.33.2/linux-ar71xx_generic/linux-3.10.17/net /netfilter/commercials$

Basically occupy the width of terminal 80%, if it can be changed to show only the last folder name is good!

Modification Method:

Vim ~/.BASHRC

Search PS1

If ["$color _prompt" = yes]; Then     ps1= ' ${debian_chroot:+ ($debian _chroot)}\[\033[01;32m\]\[email protected]\h\[\033[00m\]:\[\033[01;34m \]\w\[\033[00m\]\$ '     ps1= ' ${debian_chroot:+ ($debian _chroot)}\[email protected]\h:\w\$ ' fi

Find the above text, pay attention to the PS1 environment variable value, \u is the current user, \h is the hostname, \w is the full path, \w is to display a simple path, w into W can be!

As for if or else in effect, you can try it, mine is else in effect.

Execute command after modification

$ source ~/.BASHRC   

You can apply it! The following results

is not very concise ...
