While I was testing the new PowerShell enabled RSEE service, I used one of the many files our users send us to illustrate one thing or another or to report a bug. Using real world script files rather than some “clean” in-house samples makes for a better test as far as I am concerned.<\/p>\n
(Disclaimer: Any such script containing personal information or access information of any kind is either made to be anonymous or deleted.)<\/p>\n
While testing, I noticed that get-process produced a list style output rather than the familiar table that get-process normally emits. An hour or two of investigating this brought the script down to two lines:<\/p>\n
get-date
get-process<\/p>\n
Running those two lines from the shell worked fine, but using them inside a script “getprocesses.ps1” and running them with
.\/getprocess.ps1
produces the different output.<\/p>\n
The original script was far more complex, issuing a dated report about checking server processes running and restarting them if so required, but trimming it down to these two lines is sufficient to see the the effect.<\/p>\n
As it turns out, if you simply use get-date or any other of an assorted list of cmdlets, the output of get-process reverts back to a list rather than a table. Other cmdlets emitting tables by default are affected as well and using<\/p>\n
get-process | format-table<\/p>\n
just results in an error message.<\/p>\n
When I asked the original author of the script if he noticed that difference in output he responded as follows:<\/p>\n
“Yes, I noticed. As a matter of fact, I banged my head against this for quite some time but I found no way to make get-process print a table again. I finally gave up and learned to live with the list output.”<\/p>\n
I am hoping that knowing this will prevent some “head banging” for you guys out there. Keep in mind that the output of your cmdlets in a script may be different from what you see when using them in the shell. It seems it depends on how you mix them together.<\/p>\n","protected":false},"excerpt":{"rendered":"
