how to set a variable to accept alpha-numeric characters?

I am working on a shell program that needs to accept alpha-numeric input (i.e., P00375); when I use a simple 'read' statement to read in the input (i.e., read LOG), I receive the message "p00375: bad number". How must I adjust my input statement to accept alpha-numerics? Thanks! Brent (3 Replies)

Hello!

NAME
nagircbot - announce Nagios status to an IRC channel SYNOPSIS
nagircbot [-CdeHmRStxX] [-A REGEX] [-c CHANNEL] [-f FILE] [-F HOST[:PORT]] [-i INTERVAL] [-I INTERVAL] [-k KEYWORD] [-n NICK] [-N PREFIX] [-p PASSWORD] [-P FILE] [-s HOST[:PORT]] [-T LIST] [-u USERNAME] [-U NAME] [-z USER] DESCRIPTION
nagircbot is an IRC bot that reads Nagios' status information and emits alerts to an IRC channel. It can filter alerts based on severity (CRITICAL, HARD, SOFT, and/or UNKNOWN) or by regular expression. It can connect to IRC servers protected by password or SSL, and can optionally set the topic to the current Nagios status. OPTIONS
-A REGEX Filter (omit) lines that match a basic regular expression. -c CHANNEL Channel to connect to, including the leading "#" (default: "#nagircbot"). -C Use colors in IRC messages. -d Do not fork into the background. -e Use encryption (SSL) when connecting to the IRC server. -f FILE Path to Nagios' status.log, indicated by the 'status_file' parameter in nagios.cfg (default: "/usr/local/nagios/var/status.log"). -F HOST[:PORT] Retrieve status.log over the network. If no port is specified, the default is 33333. -H Only announce alerts in 'HARD' state. This is the default. -i INTERVAL Nagios alert check interval, in seconds (default: 60). -I INTERVAL How often to announce Nagios global status in the channel, in seconds. Specify an interval of 0 (the default) to disable. Do not specify an interval smaller than the alert check (-i) interval. -k KEYWORD Keyword for the channel (default: no keyword). -m Display status information for an alert in separate IRC messages instead of combining on a single message. -n NICK IRC nick to use (default: "nagircbot"). -N PREFIX Prefix for all in-channel IRC messages. -p PASSWORD IRC server password. -P FILE Write PID file. -R Only announce CRITICAL/UNKNOWN alerts. -s HOST[:PORT] IRC server to connect to. If not specified, the default is "localhost:6667". If no port is specified, the default is 33333. -S Also announce alerts in 'SOFT' state. -t Set the channel topic to an alert summary. -T LIST Enable checks to see if Nagios is still running. Send 'check' in a private message to invoke the check. Accepts a comma-seperated list (without spaces) with the following elements: max_time_last_host_update, max_time_oldest_host_update, max_time_last_host_check, max_time_oldest_host_check, max_time_last_service_check, max_time_oldest_service_check, and max_time_oldest_next_service_check. -u USERNAME Username to log into the IRC server as. -U NAME IRC "real" or full name (default: "nagircbot"). -x status.log is in Nagios 1.0 format. -X status.log is in Nagios 2.0/3.0 format. This is the default. -z USER User to run as. AUTHOR
