How do I add timestamps to individual lines of PowerShell & output?

Question

How, if at all, is it possible to add timestamps to each line of an output generated by the & PowerShell operator?

Example:

PS H:\\&         


        

Answer 1

You can just use ForEach-Object cmdlet for it (used % alias in below example)

ping 192.168.1.1 | %{ "{0:HH:mm:ss:fff}: {1}" -f (Get-Date), $_ }

result:

23:41:51:301:
23:41:51:302: Pinging 192.168.1.1 with 32 bytes of data:
23:41:55:255: Request timed out.
23:42:00:266: Request timed out.
23:42:05:254: Request timed out.
23:42:10:253: Request timed out.
23:42:10:261:
23:42:10:263: Ping statistics for 192.168.1.1:
23:42:10:265:     Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

Or use format like in mjolinor answer:

ping 192.168.1.1 | %{ "{0:o}: {1}" -f (Get-Date), $_ }

result:
