如何获得db2cmd运行的DB2命令的输出？

I wrote a Go cli program and ran it with Windows cmd. It then executed the following command:

db2cmd -c DB2 RESTORE DATABASE DMSCNDB FROM "C:/DB" TAKEN AT 20180522033009 ON C: INTO DMSCNDB  WITHOUT PROMPTING

Here is the Go code I used:

cmd := exec.Command("db2cmd", "-c", arg)
buf, err := cmd.Output()
if err != nil {
    log.Fatalf("Failed restoring backup with error: %s
", err)
} else {
    log.Printf("Successfully restored backup with command output: %s
", buf)
}

Everything worked fined, except for the command prompt spawned by the db2cmd. Is there any way to get the output of it? How can I get the output of DB2 command run by db2cmd?

Thank you!

I have found the answer here: https://www.ibm.com/support/knowledgecenter/en/SSEPGG_10.5.0/com.ibm.db2.luw.admin.cmd.doc/doc/r0002036.html

So, just use the -i parameter like this:

cmd := exec.Command("db2cmd", "-i", arg)
buf, err := cmd.Output()
if err != nil {
    log.Fatalf("Failed restoring backup with error:
%s
", err)
} else {
    log.Printf("Successfully ran command with output:
%s
", buf)
}
