Modify the Linux terminal prompt path length

Modify the Linux terminal prompt path length

In Linux, the default path prompts the complete path, which takes a long line and may occupy the full width! As shown below:

Bkjia @ Ubuntu :~ /Trunk-new/build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/net/netfilter/effeccials $

It basically occupies 80% of the terminal width. If you can change it to show only the name of the last folder!

Modification method:

Vim ~ /. Bashrc

Search PS1

56 if ["$ color_prompt" = yes]; then
57 PS1 = '$ {debian_chroot: + ($ debian_chroot)} \ [\ 033 [01; 32m \] \ u @ \ h \ [\ 033 [00m \]: \ [\ 033 [01; 34m \] \ W \ [\ 033 [00m \] \ $'
58 else
59 PS1 = '$ {debian_chroot: + ($ debian_chroot)} \ u @ \ h: \ W \ $'
60 fi

Find the preceding text. Note that the value of the environment variable in PS1 is the current user, \ h is the host name, \ w is the complete path, and \ W is the simple path, change w to W!

If or else takes effect, you can try it all. Mine is else.

Run the command after modification

$ Source ~ /. Bashrc

You can apply it! Result

Bkjia @ ubuntu: commercials $

Is it concise.
