After researching, I think I know the answer to this: no. But just in case I am missing something: Is there a way to globally suppress % escaping in a CMD file? Something like:
SETLOCAL NOESCAPE
MYAPP.EXE "%41%42%43%44"
So MYAPP.EXE sees the literal string:
"%41%42%43%44"
I know I can double up on the percent signs but was wondering if there is a setting that can be switched on and off.
Thanks.
No, there is no setting that allows an executed batch line to treat a percent as a literal. Percent interpretation is an integral part of how the batch parser works - See https://stackoverflow.com/a/4095133/1012053 for more info.
If you want a percent literal within an executed batch script line, than it must be doubled.
I have thought of a method of embedding and executing a command containing un-escaped percent literals, but it is an ugly hack. You put the string literal in a "labeled" comment, use FINDSTR to extract the string literal, and process that value via FOR /F. You can use multiple labels to selectively get the string you need.
@echo off
::cmd1:myapp.exe "%41%42%43%44"
::cmd2:myapp.exe "%91%92%93%94"
for /f "tokens=1* delims=:" %%A in ('findstr "^::cmd1:" "%~f0"') do %%B
for /f "tokens=1* delims=:" %%A in ('findstr "^::cmd2:" "%~f0"') do %%B
I don't know about you, but I would rather simply escape the percents ;-)
