pv.exe - PrcView command line utility allows automating common task like
figuring out if particular process is running or killing a running process
Checking if a particular process is running is easy. For example the
following command will show all instances of explorer that are running:
Setting a process priority is another common task. To set explorer priority
to normal just type:
pv -pn explorer.exe
or if you like a 'verbose' style
pv -p"Normal" explorer.exe
pv supports the common '*' and '?' wildcards so that the following command
will perfectly work by printing out all the processes starting with 'e'
Don't like a particular process and would like to kill it? The following
command will do the job:
pv -k thisprocess.exe
And if you don't like additional questions and would like to force killing:
pv -kf thisprocess.exe
Don't like this particular instance of the process and know the window title?
The following command will do the job (please note that '\' need to be
represented as a '\\' combination if you enter it from the command line):
pv -k thisprocess.exe -w"c:\\"
pv.exe can be easealy executed from a batch file to check if process is running.
When writing a command file please note that the ERRORLEVEL number specifies
a true condition if the last program run returned an exit code equal to or
_greater_ than the number specified.
The following script illustrates how this could be done:
pv.exe %1 >nul
if ERRORLEVEL 1 goto Process_NotFound
echo Process %1 is running
echo Process %1 is not running
Please note that redirecting standard errors by using 2>file_name does not work under 9x
Windows. Please use "2>file_name" instead. This notation will be processed by pv.exe.
And finally a copy of the -? command:
