Unable to run DOS command for Beyond Compare tool

[CarlFerrer]

Good day,

I am trying to use AutoIt to automate file comparison and am using the code below. BCCompare.exe is for Beyond Compare application. This stops right at the M (in red), with a syntax error. What can be the issue?

 

#include <Process.au3>

Local $iRc = _RunDos("BCompare.exe @"My Script.txt" "My File.txt" "Your File.txt" "My Report.txt"")

The second " in that line terminates the string, which makes AutoIt expect AutoIt code. Solution: "escape" the doublequotes by doubling them:

$line = "this is a ""quoted"" word"

Thanks, SadBunny!

Modified as suggested. No syntax error at this time, but still don't see my result.

Local $iRc = _RunDos("Bcompare.exe @""C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\cf_script.txt"" ""C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\subser1_1.txt"" ""C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\subser1_2.txt"" ""C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\cf_report.txt""")

When I tried this below in DOS, it works:

 

Bcompare.exe @"C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\cf_script.txt" "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\subser1_1.txt" "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\subser1_2.txt" "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\cf_report.txt"

As the helpfile for _RunDos states, the return value is the exit code of the command. If you want to read the standard output (stdout) of a command, check the helpfile for StdoutRead(). Pay attention to the example, it is somewhat less straightforward than some other commands.

Isn't this a good case for using single quotes to clarify strings being passed?

From the help file:

You can also use single-quotes like 'this' and 'here is a ' 'single-quote' ' - ok?'

You can mix quote types to make for easier working and to avoid having to double-up your quotes to get what you want.

Actually, the help file isn't quite correct.  It should show this as the example of use:

You can also use single-quotes like 'this' and 'here is a "single-quote" - ok?'

correct for error in help file's example

I would do it this way.

Local $iRc = Run('"FULLPATHTOTHEEXEFILE\Bcompare.exe "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\cf_script.txt" "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\subser1_1.txt" "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\subser1_2.txt" "C:\Users\Carlos\Desktop\MCAP_test_auto\autoit\cf_report.txt"')
