win_wait_for_process – Waits for a process to exist or not exist before continuing

New in version 2.7.

Synopsis

  • Waiting for a process to start or stop.
  • This is useful when Windows services behave poorly and do not enumerate external dependencies in their manifest.

Parameters

Parameter Choices/Defaults Comments
owner
string
The owner of the process.
Requires PowerShell version 4.0 or newer.
pid
integer
The PID of the process.
post_wait_delay
integer
Default:
0
Seconds to wait after checking for processes.
pre_wait_delay
integer
Default:
0
Seconds to wait before checking processes.
process_min_count
integer
Default:
1
Minimum number of process matching the supplied pattern to satisfy present condition.
Only applies to present.
process_name_exact
list
The name of the process(es) for which to wait. The name of the process(es) should not include the file extension suffix.
process_name_pattern
string
RegEx pattern matching desired process(es).
sleep
integer
Default:
1
Number of seconds to sleep between checks.
Only applies when waiting for a process to start. Waiting for a process to start does not have a native non-polling mechanism. Waiting for a stop uses native PowerShell and does not require polling.
state
string
    Choices:
  • absent
  • present ←
When checking for a running process present will block execution until the process exists, or until the timeout has been reached. absent will block execution until the process no longer exists, or until the timeout has been reached.
When waiting for present, the module will return changed only if the process was not present on the initial check but became present on subsequent checks.
If, while waiting for absent, new processes matching the supplied pattern are started, these new processes will not be included in the action.
timeout
integer
Default:
300
The maximum number of seconds to wait for a for a process to start or stop before erroring out.
