Speed Up Linux Workflows: Quick Dir Jump, Vim Tweaks, MySQL Prompt & System Info

1. Quick Jump Command - z

When you frequently need to cd into deep directories, typing the full path each time can be tedious. The 'z' script provides a shortcut. # cd /root/py/auto/fabric Copy the source from https://github.com/rupa/z/blob/master/z.sh into a file named z.sh in your home directory, then add source /path/to/z.sh to the end of your .bashrc. After reloading, you can jump to a previously visited directory by typing z directory_name.

# source z.sh

# . .bashrc

The script assigns a weight to each visited directory and selects the most likely target based on that weight.

2. Vim Configuration

If you often edit shell, Python, or C code with Vim, you may want a more powerful interface featuring code completion, fast file search, a directory tree, and header completion for Python and C.

Download the Vim configuration archive, extract it to your home directory, and follow the included instructions to enable the enhancements.

3. Set MySQL Prompt

To distinguish multiple MySQL sessions, add the following line to /etc/my.cnf:

[mysql]
prompt="\\u@\\h : \\d \\r:\\m:\\s>"

Reconnect to MySQL to see the new prompt.

4. View System Version

Common methods like cat /etc/issue may expose system details. A more reliable way is to use the following command: # cat /etc/*release CentOS installations also include a centos-release-<version> RPM package.

5. Check Disk Usage

Instead of the basic fdisk or df commands, you can use the following concise command to view disk usage more intuitively:

# lsblk -f
