i want to check, if an application is running.
So i use the following script, wich works just fine. The programm tlist from NT res Kit does the main part.

$process = "akit.exe"
SHELL '%comspec% /c tlist | find /i "$process" >nul'

IF @ERROR = 0
?"$process is running..."
ELSE
?"$process is not running..."
ENDIF

This way, program tlist must be within the working directory.

Using a full qualified path like

SHELL '%comspec% /c \\GUI-SERVER\GUI\tlist | find /i "$process" >nul'

still works.

But i can't figure out how to change the path to a variable like

$path = "\\GUI-SERVER\GUI\"
$process = "akit.exe"
SHELL '%comspec% /c "$path"tlist | find /i "$process" >nul'

This way, tlist is not found.
What is the correct syntax for using variables within the shell command?

Any hint is appreciated!

GOGO

Try it this way...

$path = "\\GUI-SERVER\GUI"

$process = "akit.exe"

SHELL '%comspec% /c $path\tlist | find /i "$process" >nul'

it works well, but...

I just don't understand the syntax.
Why can I use $process with and $path without quotation marks?
I do need the " quotation marks around $process and it's not possible to change ' and ".
What are the rules?

Usually I don't have logic problems within my scrips, but always a hard time about variables and syntax.
Sorry Ruud, but the documentation doesn't help me much.

Here is a hint on how I sometimes create complex shell/syntax commands.

using the code as an example....

first you set all of the variables.

$path = "\\GUI-SERVER\GUI"
$process = "akit.exe"

then instead of actually doing a shell command. Just print "?" the shell string, this will let you show you what the finished shell command will be, after the variables are defined.

? '%comspec% /c $path\tlist | find /i "$process" >nul'

quote:

---

C:\WINNT\system32\cmd.exe /c \\GUI-SERVER\GUI\tlist | find /i "akit.exe" >nul

---

now print the shell string from what you posted,

? '%comspec% /c "$path"tlist | find /i "$process" >nul'

quote:

---

C:\WINNT\system32\cmd.exe /c "\\GUI-SERVER\GUI"tlist | find /i "akit.exe" >nul

---

see the error in the syntax?
