Linux tool direct to common directory avoid frequent CD switch directory

Copy the source code to the z.sh file in your user directory and open it with vim. BASHRC This directory, add "source/home/yourname/z.sh" at the end.

Then go back to shell execution: source. bashrc. So this thing will come into effect.

For example, after running CD/HOME/A/B/C/D, Linux enters the D directory and then enters Z

This is the system will save the path/home/a/b/c/d to D, next time you just enter Z D in the shell this can go directly into the directory/HOME/A/B/C/D. Very convenient
