When the shell is running in EnableDelayedExpansion mode the! This changes slightly if you are running with DelayedExpansion of variables: if any part of the command line includes an '! If a single parameter contains spaces, you can still pass it as one item by surrounding in "quotes" - this works well for long filenames. If a parameter is used to supply a filename like this:.
I never would have guessed it was wscript 's fault! Leave it to Windows : — Software. Windows: the OS where globbing, shell expansion, and parameter unescaping is performed by the executable being invoked instead of the shell. You never know which convention, if any, the invoked executable honours. Valuable input: blogs. The caret is indeed the escape character of choice for cmd. Show 5 more comments. Try this: myscript """test""" "" escape to a single " in the parameter.
That's not quite correct. Try myscript """test test""" and it doesn't work first parameter is handed over as "test.
Acutally, you need three quotes: myscript """"test test"" The third quote at the end can be skipped, though. Can someone help? Thank you.

I was beating my head on the wall trying to run a vbscript with cmd prompt text being echoed into cmd prompt text - I inherited this - and could not figure out a way to escape the quotes. Iow it is not entirely shell only.

There's another way to do it though, dealing with multiple quotes i. Add a comment. Active Oldest Votes. Here's a set of basic rules: When not wrapped in double-quoted groups, spaces separate parameters: program param1 param2 param 3 will pass four parameters to program.
A double-quoted group ignores spaces as value separators when passing parameters to programs: program one two "three and more" will pass three parameters to program. Now to explain some of the confusion: Double-quoted groups that appear directly adjacent to text not wrapped with double-quotes join into one parameter: hello"to the entire"world acts as one parameter: helloto the entireworld.
Note: The previous rule does NOT imply that two double-quoted groups can appear directly adjacent to one another. Any double-quote directly following a closing quote is treated as or as part of plain unwrapped text that is adjacent to the double-quoted group, but only one double-quote: "Tim says, ""Hi! Here's the breakdown of that last confusing line: " open double-quote group T inside ""s i inside ""s m inside ""s inside ""s - space doesn't separate s inside ""s a inside ""s y inside ""s s inside ""s , inside ""s inside ""s - space doesn't separate " close double-quoted group " quote directly follows closer - acts as plain unwrapped text: " H outside ""s - gets joined to previous adjacent group i outside ""s From this, it should be recognizable that therefore, inside and outside quotes, three double-quotes act as a plain-text unescaped double-quote: "Tim said to him, """What's been happening lately?

I believe the behavior you're describing is that of Microsoft's standard C library, which I think is also duplicated by most other Windows C compilers.
Multiple errors in your last exepriment. All I can say is, Windows batch files have problems. This is escaping quotes , for Christ's sake; it shouldn't have to be some kind of rocket science. JamesKo I couldn't agree more.
The arcane absurdity and inconsistency of the Windows command line never fails to anger me. Who designed this junk? Oh, the hours wasted over the years! Unix is so easy and makes so much sense in comparison. Show 2 more comments. Then maybe the answers to this question might help you further? I never would have guessed it was wscript 's fault!
