How can findstr return not a whole string, but a substring that satisfies the regular expression?

Question

cmd/bat

Team

findstr /R ".-.-.-..-..........-..........-..........-...." temp.txt

returns a string with spaces and a newline character at the end, but you need a string like
".-.-.-..-..........-..........-... .......-...."
without unnecessary garbage.
How to do it?

Answer 1

You need to put the output of findstr into for /f and there already cut, divide into parts, etc. above each line.
Schematically like this:

for /f "tokens=*" %%a in ('findstr /R ...') do (
  echo.%%a
)

For reference:for /?

Answer 2

I can recommend GnuWin32, a set of utilities from a UNIX-like system, but under Windows.
There, in particular, there is grep, it will give the required piece from the line ...
