Note: according to PowerShell, there is no error and command is executed successfully. For example: I tried to download a package from SVN Link. The Link actually is not present. The script is showing me error message on the console. However, when I tried to check $_ or $? or $error, I did not see any error message. However, $LASTEXITCODE returned value http://stackoverflow.com/questions/17420474/how-to-capture-error-messages-thrown-by-a-command 1.

Are you invoking an external tool or using a cmdlet? –mike z Jul 2 '13 at 8:12 Hi Mike, I am using the command - svn --force export $SVN . –Avinash Ganesh Jul 2 '13 at 8:46 add a comment| 2 Answers 2 active oldest votes up vote 9 down vote accepted If you get an error message, you need to capture the error stream: $msg = command 2>&1 or command 2>error.txt PowerShell writes its messages to different streams that can be redirected to files for capturing the respective output. Stream 1 (default): regular output ("STDOUT") Stream 2: error messages ("STDERR"), including error messages from external programs Stream 3: warning messages Stream 4: verbose messages Stream 5: debug messages To capture a particular stream in a file you need to redirect the stream number to a file name. For instance command 2>"C:\path\to\error.log" would capture all error messages produced by command in the file C:\path\to\error.log. Use 2>> instead

Why DOS output of DEL commands to a file won't display error messages? P: 2 vhogan Hi. Yes DOS still lives.... I am directing multiple delete (DEL) commands to an output file e.g. del /F /Q D:\Oracle\CoreMid\Apache\Apache\logs\*.* >vh.txt del /F /Q D:\Oracle\Core\Apache\Apache\logs\*.* >>vh.txt del /F /Q D:\Oracle\CoreMid\opmn\logs\*.* >>vh.txt del /F /Q D:\Oracle\CoreMid\webcache\logs\*.* >>vh.txt del /F /Q D:\Oracle\CoreInfra\opmn\logs\*.* >>vh.txt I am appending the output in each case except line 1 - that part is ok. However when there is an error message it doesnt appear in the output file. For example if I run this command (del /F /Q D:\Oracle\CoreMid\opmn\logs\*.*) at Dos prompt I get: D:\Oracle\CoreMid\opmn\logs\HTTP_Server~1 The process cannot access the file because it is being used by another process. D:\Oracle\CoreMid\opmn\logs\ipm.log The process cannot access the file because it is being used by another process. D:\Oracle\CoreMid\opmn\logs\OC4J~home~default_isla nd~1 The process cannot access the file because it is being used by another process. However if I run it with output to file vh.txt i get: D:\Oracle\CoreMid\opmn\logs\HTTP_Server~1 D:\Oracle\CoreMid\opmn\logs\ipm.log D:\Oracle\CoreMid\opmn\logs\OC4J~home~default_isla nd~1 As you can see there are no error message in the output results that are written to file, but they are displayed if output is to screen. How can I capture the error messages in the output file???

You need to redirect messages to stderr to stdout and messages to stdout to your file. You can redirect messages to stderr to stdout using the syntax "2>&1" (pipe stream 2 to stream 1) so you whole command should be del /F /Q D:\Oracle\CoreMid\Apache\Apache\logs\*.* >vh.txt 2>&1 Jan 13 '11 #2 reply P: 2 vhogan Thanks Banfa, that was very helpful and what's more it worked first time!!!
