CLI Reference & Tips

Find your public IP address:

 dig +short myip.opendns.com @resolver1.opendns.com

Lookup command examples:
```
 curl -s cheat.sh/<command>
```
Zsh does not enable a builtin help command, instead it provides run-help. By default run-help is an alias to man and will only work on external commands. To use it for Zsh builtins and features, load and unalias the command in your .zshrc.
```
 autoload -Uz run-help
 unalias run-help
 alias help=run-help # for convenience
```

To remove duplicate lines from unsorted data:

 echo "Apple\nOrange\nOrange \nBanana\nApple\nPineapple" > file1
 awk '!a[$0]++' file1
 Apple
 Orange
 Banana
 Pineapple

To merge text files side-by-side:

 echo "HEADER1\nData-1\nData-2" > file1
 echo "HEADER2\nValue-1\nValue-2" > file1

 paste file1 file2
 HEADER1 HEADER2
 Data-1  Value-1
 Date-2  Value-2
