@comspec using &&

[mikelee33]

I simply can not get the syntax correct to utilize '&&' in the following line:

RunWait (@comspec & ' /k ' &$prog &' '&$option&' '&GUICtrlRead($file)''&&'echo Finished!')

I think I'm close, but I'm not certain. Many thanks for any direction.

You're trying to issue multiple commands to @comspec, right? Never got that working this way. The only way I succeeded was like shown in my Example 'Pipe to @ComSpec'.

Try this:

RunWait(@ComSpec & ' /k ' & $prog & ' ' & $option & ' ' & GUICtrlRead($file) & ' & & echo Finished!')

Below code also not work for you?

RunWait(@ComSpec & " /k dir /b c: && Echo. && Echo finished")

RunWait(@ComSpec & " /k dir /b c: && Echo. && Echo finished")

This works great, nicely done !

Yeah, you're right , works for me this way. Forgot that he's running it without pipes. What didn't work for me was piping several commands to stdout using one instance of @comspec that way (e.g. to chcp):

#include <Constants.au3>
$foo = Run(@ComSpec & " /k dir /b c: && Echo. && Echo finished", @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD)
$line = ""
While 1
    $line &= StdoutRead($foo)
    If @error Then ExitLoop
Wend
MsgBox(0,"","Finished" & @crlf & @crlf & @crlf & $line)





$foo = Run(@ComSpec, "", @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD)
StdinWrite($foo, "dir /b c:" & @CRLF)
StdinWrite($foo, "echo. Echo finished" & @CRLF)
StdinWrite($foo, "exit" & @CRLF); send exit command to trigger stdout
$line = ""
While 1
    $line &= StdoutRead($foo)
    If @error Then ExitLoop
Wend
MsgBox(0,"","Finished" & @crlf & @crlf & @crlf & $line)

RunWait(@ComSpec & ' /k ' & $prog & ' ' & $option & ' ' & GUICtrlRead($file) & ' & & echo Finished!')

Sorry, no, that didn't work for me. The first command executed, but not the echo.

Your second example: RunWait(@ComSpec & " /k dir /b c: && Echo. && Echo finished") does work as you've written it but when I apply that approach it didn't work. Might it be how the first program terminates that causes an issue with how the second executes?

Your first example contain error, you not indicate a working directory

Meaning:

Command1 && Command2; Run second command if first command executed successfully
Command1 || Command2; Run second command if first command executed unsuccessfully

You're right... but you'll have also to append an Exit to trigger the stdout, then it works both ways, you'll live while you learn ...

#include <Constants.au3>
; Example 1
$foo = Run(@ComSpec, "", @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD)
StdinWrite($foo, "dir /b c:" & @CRLF)
StdinWrite($foo, "echo. Echo finished" & @CRLF)
StdinWrite($foo, "exit" & @CRLF); send exit command to trigger stdout
$line = ""
While 1
    $line &= StdoutRead($foo)
    If @error Then ExitLoop
Wend
MsgBox(0,"","Finished" & @crlf & @crlf & @crlf & $line)


; Example 2
$foo = Run(@ComSpec & " /k dir /b c: && Echo. && Echo finished && Exit", 'c:\', @SW_HIDE, $STDOUT_CHILD)

$line = ""
While 1
    $line &= StdoutRead($foo)
    If @error Then ExitLoop
Wend
MsgBox(0,"","Finished" & @crlf & @crlf & @crlf & $line)

(updated my example 'Pipe to @ComSpec')
