Here’s a batchfile I just wrote. I tested most of the features and it seemed to work, but it’s a “beta” prototype! you may need to tinker with it, and you will need PKZIP and PKUNZIP utilities: http://pkzip.soft32.com/free-download/ (My version is OLD, so newer version you may need to tweak, especially “getname” subroutine).
::======= PASS.BAT
@echo off & setlocal
:: set your zipped-filename here. It has no relation to your primary text
:: file name! I’m just using the batchfile name for the zipfile.
:: pkzip may be found at: http://pkzip.soft32.com/free-download/
:: among others
set zipfile=%~n0
set pass=%1
if not defined pass (
echo usage: %~n0 password [search-string]
echo If no search-string is given, the original textfile will be
echo restored to allow editing. If search-string is %~n0, and the
echo file exists, it will be re-zipped using the given password.
goto :eof
)
call :getname
echo.
echo primary (text) filename: “%primary%”, zipfilename: “%zipfile%”
if /i “%~n2” equ “%~n0” goto :rezip

::========= end batch
The textfile can be any format, but it’s best to put the password on the same line with the string that you can use to recognize it. f/e:

so in the above
PASS mypwd CARD
will give you any lines that have “card” in the line (upper or lower case no matter)
PASS mypwd
unzips the file for editing
PASS mypwd pass
rezips (and removes the primary text) file after editing.
