Please follow Xiaobian's train of thought to slowly deepen, together to study and learn "how to modify the path length of the command line prompt path prompt under linux".

Basically, the default path prompt under the Linux system is the complete path, which is really long and inconvenient, which means that sometimes it may occupy the full width and look dazzling, as in the following example:

Linuxidc@Ubuntu:~/trunk-new/build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.10.17/net/netfilter/commercials$

Basically occupy 80% of the width of the terminal, if only can be changed to display only the name of the last folder!

Modify method:

The code is as follows:

Vim / .bashrc

Search PS1

The code is as follows:

If ["$color_prompt" = yes]; then

PS1='$ {debian_chroot:+ ($debian_chroot)}\ [\ 033 [01Ex32m\]\ u@\ h\ [\ 033 [00m\]:\ [\ 033 [01transfer34m\]\ W\ [\ 033 [00m\]\ $'

Else

PS1='$ {debian_chroot:+ ($debian_chroot)}\ u @\ h:\ W\ $'

Fi

Find the text above and notice the value of the environment variable of PS1.\ u is the current user,\ h is the hostname,\ w is the full path, and\ W is the simple path. Just change w to W!

As for whether if or else is effective, you can try both, mine is else effective.

Execute the command after modification

The code is as follows:

$source ~ / .bashrc

It can be applied! The results are as follows

Linuxidc@ubuntu:commercials$
