Command Line User Interface
armshell
Description
The armshell command provides an environment for executing multiple
CLUI commands without the overhead imposed in the standard environment.
When executing a command in the standard environment, each command
opens the Java Virtual Machine (JVM), executes, then closes the JVM. When
executing multiple commands, this continued opening and closing of the JVM
increases the time required for command execution.
To avoid this situation, armshell opens the JVM once and keeps it open
until you close it. This improves performance when executing multiple
commands. A file containing CLUI commands can also be passed to armshell,
automating frequently-used task sequences .
The exit command is used to close armshell.
Syntax
armshell [ -e [on|off] ] [ < command_filename ]
armshell -?
Option

< command_filename Passes the CLUI commands stored in the specified file to armshell for
execution.
-? Display extended help message. Overrides all other switches.
< filename Use the specified file as standard input. If more than one argument is given,
only the first argument is used. All other arguments are ignored, except for the
> command.
