powershell - Remove lines based upon string -

i have error log file want copy lines don't match set error strings. building separate file of unrecognised errors.

i define know error types

# define error types need search on  $error_1 = "start date must between 1995 , 9999" $error_2 = "system.contact_type" $error_3 = "duplicateexternalsystemidexception" $error_4 = "from date after date in address" $error_5 = "missing coded entry  provider type category record" 

and doing read in file

(get-content $path\temp_report.log) |     where-object { $_ -notmatch $error_1 } |     out-file $path\uncategorised_errors.log (get-content $path\temp_report.log) |     where-object { $_ -notmatch $error_2 } |     out-file $path\uncategorised_errors.log (get-content $path\temp_report.log) |     where-object { $_ -notmatch $error_3 } |     out-file $path\uncategorised_errors.log
