CONTINUE_ON_ERROR Variable
Cisco Content Services Switch Administration Guide

Within the CLI, there are sets of predefined variables that you can use in scripts
to add more power to your scripts. Some of these predefined variables change how
scripts react, while others are merely informational variables. None of the special
variables requires user intervention for cleanup. However, it is good practice to
remove both the CONTINUE_ON_ERROR and the EXIT_MSG variables
following the execution of their relevant command blocks.
The informational variables are:
LINE - Line name (for example, pty1, console, etc.).
•
MODE - Current mode of command (for example, configure, boot, service).
•
USER - The currently logged in user (for example, admin, bob, janet).
•
ARGS - A list of arguments passed to a script from the CLI. See
•
Command Line Arguments"
UGREP - A line of text obtained using the grep -u command.
•
•
CHECK_STARTUP_ERRORS - A session variable that determines
whether or not a user is informed of startup errors upon login.
Use the CONTINUE_ON_ERROR variable to control how a script that is
executing in an interactive CLI session handles command failure. By default, a
script terminates when it encounters an error. For example, if you use the echo
command to print out information from a script and spell the command
incorrectly, the script exits with a syntax error and prints out the line in which the
error occurred. For example, enter:
! Spell echo incorrectly
eco "This will not print"
