Linux CLI Basics#

Commands#

  • pwd
  • cd
  • ls
  • clear
  • cat
  • less
  • tail
  • touch
  • cp
  • mv
  • rm
  • mkdir
  • rmdir
  • which
  • help
  • man
  • find
  • grep
  • echo
  • exit
  • sudo

Optional#

  • hostname
  • export
  • env
  • apropos
  • xargs
  • file
  • type

Proposed Lab#

  • Sean L's python CLI text-adventure game?
  • Terminus CLI Game?
  • Live screen session share where a coach/mentor asks questions to determine whether or not agent is proficient in the terminal, answers questions, and shows appropriate answers, if agent is confused?
  • This should probably only take about 20-30 minutes.
  • This is similar to the practical exams that London taxi-drivers have to take where they have an oral exam given by a proctor.
  • How else do we measure true understanding/proficiency with basic CLI skills?

MySQL Basics#

Import/Export#

Use mysql and mysqldump to import/export databases.

Introduce basic mysql shell commands#

mysql -u root -p

SHOW DATABASES;
USE db_name;
SELECT * FROM tbl_name;
CREATE DATABASE db_name;
DROP DATABASE db_name;
SHOW tables;
DESCRIBE tbl_name;
...

WP-CLI#

IIRC some wp-cli is covered in training, but a more in-depth treatment of common tasks done with the wp-cli might be covered here.

I'm not sure if this would be useful, I need to review this guide more in depth, but this was recommended to me by a WP dev, so could be a good intro to the WP application which may facilitate troubleshooting WP issues.

  • Disable plugins
  • Purge W3TC
  • Activate different theme

Basic Networking#

  • dig
  • host

Intro to disk utilization#

  • du
  • df

Intro to yum#

Using yum and running system updates

Mail log searching and parsing#

An overview on grep

Status monitoring#

Anything that needs root basically.

Ideas from Reece O.#
