PsExec Command-Line Options
Let’s take a look at PsExec’s command-line options. They control aspects of process
performance, remote connectivity, runtime environment, and whether PsExec should wait for
the target process to exit. Table 6-1 summarizes these options, which are discussed in more
detail after the table.
TABLE 6-1 PsExec Command-Line Options
Option
Description
–d Doesn’t wait for the process to terminate. (This is described earlier in the “Remote
Process Exit” section.)
Process Performance Options
–background
–low
–belownormal
–abovenormal
–high
–realtime
Runs the process at a different priority.
–a n,n… Specifies the CPUs on which the process can run.
Remote Connectivity Options
–c [–f|–v] Copies the specified program from the local system to the remote system. If
you omit this option, the application must be in the system path on the remote
system. Adding –f forces the copy to occur; –v performs a version or timestamp
check and copies only if the source is newer.
–n seconds Specifies timeout in seconds when connecting to remote computers.
Runtime environment options
–s Runs the process in the System account.
–i [session] Runs the program on an interactive desktop.
–x Runs the process on the Winlogon secure desktop.
–w directory Sets the working directory of the process.
–e Does not load the specified account’s profile.
–h Uses the account’s elevated context, if available.
–l Runs the process as a limited user.
Process Performance Options
By default, the target process runs with normal priority. You can set the process priority
of the target process by specifying any of the following on the PsExec command line:
– background, –low, –belownormal, –abovenormal, –high, and –realtime. The
– background option is supported only on Windows Vista and newer; in addition to setting
the process priority to Low, it sets the process’ memory priority and I/O priority to Very Low.
