30 HP Integrity rx2600 server and HP workstation zx6000 Operation and Maintenance Guide
System Configuration
Error Handling in Scripts
By default, if an error is encountered during the execution of a command in a batch script, the
script will continue to run. The
lasterror shell variable enables batch scripts to test the results of
the most recently run command using the
if command. This variable is not an environment
variable, but is a special variable maintained by the shell for the lifetime of that instance of the
shell.
Comments in Script Files
Comments can be embedded in batch scripts. The # character on a line denotes that all characters
on the same line and to the right of the
# are to be ignored by the shell. Comments are not echoed
to the console.
