I've been using (and loving) fish shell for a little while now, and I still frequently discover clever behaviors that make my CLI tasks more enjoyable.
|

|

Today's discovery: fish will automatically escape single quotes when pasting text into the command line.
|
|||
|
|
|
|||
|
|
=> https://fishshell.com/docs/current/cmds/fish_clipboard_paste.html fish_clipboard_paste - get text from the system’s clipboard
|
|||
|
|
|
|||
|
|
> If it outputs to the commandline, it will automatically escape the output if the cursor is currently inside single-quotes so it is suitable for single-quotes (meaning it escapes ' and \\).
|
|||
|
|
|
|||
|
|
So if I work up an ugly one-liner for determining the IP address of whatever interface is attached to the default route:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
ip addr show $(ip route | grep default | awk '{print $5}') | grep 'inet ' | awk '{print $2}' | cut -d/ -f1
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
And then decide I'd like to make that into a reusable alias, I can copy that line and paste it in after
|
|||
|
|
|
|||
|
|
=> https://fishshell.com/docs/current/cmds/alias.html alias - create a function
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
alias get_ip='
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
and fish will automagically take care of escaping all those troublesome single quotes
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
alias get_ip='ip addr show $(ip route | grep default | awk '{print $5}') | grep 'inet ' | awk '{print $2}' | cut -d/ -f1'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Neat!
