Searching easy way to remove double quotes around parameters?

[pstein]

I wrote a batch script which receives files with pathes as parameters.

As

Code: Select all

set file=%1
echo processing %file%

shows the file parameter is always enclosed in double quotes.
How can I remove them in the most easy way (= a one liner)?

Do I really have to use (two) substring operations on the variable?

Is this what you want?

Code: Select all

@Echo Off
Set "file=%~1"
Echo Processing %file% ...
Pause

[pstein]

Sorry no.

The problem is that %1 contains from the very beginning a double quotes string like

%1 = "D:\foo\bar\mypic.hpg"

This implicite assignment is not done by me but the WindowsOS when I drap a file onto the batch script

Any other idea?

@OP

What is the diffrence between %1 and %~1 ?

You were given the correct solution. I do drag and drop on pretty much all the batch files I create for my fellow employees. The tilde removes the surrounding quotes.

Open up a cmd prompt and read the help for the CALL and FOR commands.
CALL

Code: Select all

 Substitution of batch parameters (%n) has been enhanced.  You can
    now use the following optional syntax:

        %~1         - expands %1 removing any surrounding quotes (")

FOR

Code: Select all

In addition, substitution of FOR variable references has been enhanced.
You can now use the following optional syntax:

    %~I         - expands %I removing any surrounding quotes (")

Hmm, I tried it again......and it works.

Must have been a bug in command interpreter the previous time



Thank you for the solution and sorry for the confusion
