You may redirect each by doing the following: scriptname > file1 2> file2 file1 will then contain the normal output from the script and file2 would contain any error output. You can combine the output to a single file by doing the following: scriptname > filename 2>&1 or scriptname &> filename In both cases, both standard output and error output will be redirected to filename. The one danger is that this form of redirection will overwrite the file. You can also do a pair of >> to "append" if the file already exists. BTW, the pipe character is used to "chain" the output of the command on the left of the pipe as input to the command on the right of the pipe. HTH, --Rob
