Hi all-
I have a variable that contains a web page:
echo $STUFF
<html> <head> <title>my page</title></head> <body> blah blah etc..
Can I use the shell's parameter expansion abilities to remove just the tags?
I thought that FIXHTML=${STUFF//<*>/} might do it, but it didn't seem to... (2 Replies)
Say you have this numeric variable that can be set by the user but you never want it to leave a certain range when it gets printed. How could you use parameter expansion such that it will never expand outside of that boundary? Thanks

I am using bash and resetting IFS as below when reading the command line arguments. I do this so I can call my script as in Ex1.
Ex1: ./synt2d-ray3dmod.bash --xsrc=12/20/30
This allows me to split both sides so that when I do "shift"
I can get 12/20/30

snmp_standard_mib(3erl) Erlang Module Definition snmp_standard_mib(3erl)NAME
snmp_standard_mib - Instrumentation Functions for STANDARD-MIB and SNMPv2-MIB
DESCRIPTION
The module snmp_standard_mib implements the instrumentation functions for the STANDARD-MIB and SNMPv2-MIB, and functions for configuring
the database.
The configuration files are described in the SNMP User's Manual.
EXPORTS
configure(ConfDir) -> void()
Types ConfDir = string()
This function is called from the supervisor at system start-up.
Inserts all data in the configuration files into the database and destroys all old rows with StorageType volatile . The rows created
from the configuration file will have StorageType nonVolatile .
All snmp counters are set to zero.
If an error is found in the configuration file, it is reported using the function config_err/2 of the error report module, and the
function fails with the reason configuration_error .
ConfDir is a string which points to the directory where the configuration files are found.
The configuration file read is: standard.conf .
inc(Name) -> void()
inc(Name, N) -> void()
Types Name = atom()
N = integer()
Increments a variable in the MIB with N , or one if N is not specified.
reconfigure(ConfDir) -> void()
Types ConfDir = string()
Inserts all data in the configuration files into the database and destroys all old data, including the rows with StorageType non-
Volatile . The rows created from the configuration file will have StorageType nonVolatile .
Thus, the data in the SNMP-STANDARD-MIB and SNMPv2-MIB, after this function has been called, is from the configuration files.
All snmp counters are set to zero.
If an error is found in the configuration file, it is reported using the function config_err/2 of the error report module, and the
function fails with the reason configuration_error .
ConfDir is a string which points to the directory where the configuration files are found.
The configuration file read is: standard.conf .
reset() -> void()
Resets all snmp counters to 0.
sys_up_time() -> Time
Types Time = int()
Gets the system up time in hundredth of a second.
