15. Aliases instruct the shell to replace one string with another when executing commands. @chiamakaikeanyi
16. • Git • Docker • Kubernetes • . . . Popular usage @chiamakaikeanyi
17. isLong && repetitive ? alias : null Alias every command? @chiamakaikeanyi No, Not really
18. Who needs to use aliases? @chiamakaikeanyi
19. Lazy software engineers @chiamakaikeanyi
20. gac "Fix filters" gpo patch/filters git add . git commit -m "Fix filters" git push origin patch/filters Works Smart Works Hard
21. How can you add aliases? @chiamakaikeanyi
22. Syntax alias name=command @chiamakaikeanyi
23. Syntax alias name="command with space" @chiamakaikeanyi
24. Store in the home directory @chiamakaikeanyi
25. Bourne-again shell (Bash): ~/.bashrc or ~/.bash_profile Z Shell (ZSH): ~/.zshrc Default Files @chiamakaikeanyi
26. echo $SHELL cd ~ ls -la touch ~/.bash_profile Not Found? @chiamakaikeanyi
27. alias workspace= "git config user.name 'your_name' && git config user.email 'your_email'" @chiamakaikeanyi
28. alias blog="open https://chiamakaikeanyi.dev" @chiamakaikeanyi
29. alias nis='f(){ npm install --save "$@" }; f' @chiamakaikeanyi
30. source ~/.zshrc or . ~/.zshrc Reload @chiamakaikeanyi
31. nano ~/.zshrc open ~/.zshrc code ~/.zshrc alias @chiamakaikeanyi Accessing your Aliases NB: Substitute .zshrc with the shell you’re using - .bashrc or .bash_profile ...
32. BASH @chiamakaikeanyi
33. At the end… What matters is becoming more productive @chiamakaikeanyi
34. Demo Let’s see an example @chiamakaikeanyi
35. https://github.com/chiamakaikeanyi/dotfiles Resource @chiamakaikeanyi
36. Tomorrow is mystery But you can save time By using Aliases - Chiamaka Ikeanyi @chiamakaikeanyi Yesterday is history
