How To Windows Commands Exit with the Wrong Code¶
Windows commands often exit with a 0 code, even if the command fails. Catch errors like this using Select-String;
the Powershell equivalent of grep
.
1 2 3 4 5 6 7 8 | echo "Attempting to sync Group Policy..." $out = gpupdate echo $out $result = Select-String -InputObject $out -Pattern "error" if ($result.length -ne 0) { exit 1 } |
