About the Command Line Interface
25
When the CLI encounters either type of error, it writes information
describing the error directly to the command line and sets a return code.
Depending on the return code, the CLI might also write additional
information about which parameter caused the error. The CLI also writes
information about what command syntax was expected to help you identify
any syntax errors you might have entered.
When an exception occurs while executing a command, the CLI
automatically saves the error information to a file named excprpt.txt. The
CLI attempts to place excprpt.txt in the directory specified by the system
property devmgr.datadir, which by default is the "client/data" directory under
the main installation directory in Windows and the /var/opt/SM directory in
Linux. If for any reason the CLI cannot place the file in the devmgr.datadir-
specified directory, the CLI saves the excprpt.txt file in the same directory
from which the CLI is running. You cannot change the file name or location.
The excprpt.txt file is overwritten every time an exception occurs. To save the
information in the excprpt.txt file, you must to copy the information to a new
file or directory.
