I am particularly confused with these types of usage:
Code: Select all
:foreach i in=[/ip addr find] do={
Code: Select all
:foreach i in=[find]
Code: Select all
/ip firewall address-list find list="fwaddlist"
:find vs. find
Does anyone know of a good tutorial (preferably a video) that explains how to use the find command?

Thank you.

Re: :find vs. find
The full tutorial is the manual, but the TL;DR is:
- :find can be used to find a position of an element in an array or a position of a substring in a string:
:local myArray {"127";"226";"313"} ; put [:find $myArray "226" 0] ; put ($myArray->1)
1
226
:local myString "abcdef" ; :put [:find $myString "cde" 0]
2 - find can be used to create a list of internal IDs of configuration items of the same type that match the condition expression following the find keyword:
/ip/address/print ; /ip/address {:put [find where interface=ether2] ; :foreach addr in=[find where interface=ether2] do={:put [get $addr network]}}

Re: :find vs. find
You wrote the same thing three times... and never :find
1 + 2 + 3 = 2 + 1 + 3 = 3 + 2 + 1 = etc. etc. etc.
:foreach i in=[/ip addr find] do={ is the same of :foreach i in=[find] if the context is already /ip address,
so temp in this case
and on this is the same
but this is wrong, because search not on addresses
The correct form depend on context.

Code: Select all
/ip address
:local temp [find]
Code: Select all
/interface
:local temp [/ip address find]
Code: Select all
/interface
:local temp [find]

Re: :find vs. find
As noted, it's really TWO different commands. But it generally get the right one since when you [find]... The reason is kinda dorky... the [] cause a new subprocess, but it take the "path" of the part of the "parent command" as the context of what's inside. So with something like /ip/address/set [find] comment="same-comment-on-all" - the find takes it path from the outer "/ip/address", so the find refers to the "match attributes version" of find. So to do the "string search version", you'd need the [:find] (or, even [/find]) form since that ONLY exists at the / "root" of the command tree. Basically there is always some `cwd` (current working directory) in the shell, which allow the "right" find to be used.
On the dorky side, you can see two different find's with /console/inspect:
