As for the command T uses above, I was surprised to
learn my OS has a "find" command and a "findstr"
command, which perform the same function, but
have different available options. These are
similar to "grep". Weird, that they provide two
utilities like that.

I've been using "find" for at least 10 years to get a quick list of my
current IP addresses. I travel for work, so things change every time I
set up at a customer site or stay at a hotel.

C:\Windows\System32ipconfig | find "IPv4"
IPv4 Address. . . . . . . . . . . : 192.168.111.210
IPv4 Address. . . . . . . . . . . : 192.168.31.1
Autoconfiguration IPv4 Address. . : 169.254.134.50

***

C:\Windows\System32find /?
Searches for a text string in a file or files.

FIND [/V] [/C] [/N] [/i] [/OFF[LINE]] "string" [[drive:][path]filename[
....]]

/V Displays all lines NOT containing the specified string.
/C Displays only the count of lines containing the string.
/N Displays line numbers with the displayed lines.
/I Ignores the case of characters when searching for the string.
/OFF[LINE] Do not skip files with offline attribute set.
"string" Specifies the text string to find.
[drive:][path]filename
Specifies a file or files to search.

If a path is not specified, FIND searches the text typed at the prompt
or piped from another command.

***

C:\Windows\System32findstr /?
Searches for strings in files.

FINDSTR [/b] [/E] [/L] [/R] [/S] [/i] [/X] [/V] [/N] [/M] [/O] [/P]
[/F:file]
[/C:string] [/G:file] [/D:dir list] [/A:color attributes]
[/OFF[LINE]]
strings [[drive:][path]filename[ ...]]

/B Matches pattern if at the beginning of a line.
/E Matches pattern if at the end of a line.
/L Uses search strings literally.
/R Uses search strings as regular expressions.
/S Searches for matching files in the current directory and
all subdirectories.
/I Specifies that the search is not to be case-sensitive.
/X Prints lines that match exactly.
/V Prints only lines that do not contain a match.
/N Prints the line number before each line that matches.
/M Prints only the filename if a file contains a match.
/O Prints character offset before each matching line.
/P Skip files with non-printable characters.
/OFF[LINE] Do not skip files with offline attribute set.
/A:attr Specifies color attribute with two hex digits. See "color
/?"
/F:file Reads file list from the specified file(/ stands for
console).
/C:string Uses specified string as a literal search string.
/G:file Gets search strings from the specified file(/ stands for
console).
/D:dir Search a semicolon delimited list of directories
strings Text to be searched for.
[drive:][path]filename
Specifies a file or files to search.

Use spaces to separate multiple search strings unless the argument is
prefixed
with /C. For example, 'FINDSTR "hello there" x.y' searches for "hello"
or
"there" in file x.y. 'FINDSTR /C:"hello there" x.y' searches for
"hello there" in file x.y.

Regular expression quick reference:
. Wildcard: any character
* Repeat: zero or more occurrences of previous character or
class
^ Line position: beginning of line
$ Line position: end of line
[class] Character class: any one character in set
[^class] Inverse class: any one character not in set
[x-y] Range: any characters within the specified range
\x Escape: literal use of metacharacter x
\xyz Word position: beginning of word
xyz\ Word position: end of word

Command
Reference.
