Shell scripting

Hello,

I have this code to submit a job to cluster in a genomic analysis.

I can't fully understand the first lines of the code:

Code:
ref=$1 
read1=$2 
read1=${read1#*/} 
read=${read1%_*_*}

ref=$1 means that ref has become a variable.
read1=$2 means that read1 has become the name of the second variable.

Is that correct? what are the meanings of the third and fourth lines. Does it have something with the names of the files?

Thanks a lot in advance.

NAME
cmannotifyd - CMAN Notification Daemon SYNOPSIS
cmannotifyd [-f] [-d] DESCRIPTION
The cmannotifyd daemon talks to CMAN and provides a mechanism to notify external entities about cluster changes. CMAN dispatches 3 kind of notifications: - CMAN_REASON_TRY_SHUTDOWN when cman requests to all clients if it is allowed to shutdown. - CMAN_REASON_STATECHANGE when cman detects a node joining or leaving the cluster. - CMAN_REASON_CONFIG_UPDATE when a configuration change event has been detected/requested. These notifications are then dispatched to the shell script cman_notify in the environment variable CMAN_NOTIFICATION. cman_notify will then execute all the scripts in the configured notification directory (default: /etc/cluster/cman-notify.d) passing a very minimal set of envvars including, of course, the CMAN_NOTIFICATION= type. The execution order is set by the filename as shown by "LC_ALL=C ls -las". cmannotifyd logs are stored in the default log file (/var/log/cluster/cmannotifyd.log). cman_notify logs are stored in the default log file (/var/log/cluster/cman_notify.log). By default the output from the scripts executed by cman_notify is redirected to /dev/null. Users can either set CMAN_NOTIFICATION_DEBUG=1 in their environment or set proper debug configura- tion in cluster.conf to redirect scripts output to the cman_notify log file. NOTES
cmannotifyd does not block on cman_notify nor check the exit status of the script. Notifications are dispatched in the same order as they arrive, one by one. CMAN_REASON_TRY_SHUTDOWN is passed to scripts for information only, they can not influence cman's decsion about whether or not to shut down. CMAN_REASON_STATECHANGE also implies CMAN_NOTIFICATION_QUORUM exported in the environment. CMAN_NOTIFICATION_QUORUM will be set to 1 (when the node is part of a quorate cluster) or 0 (otherwise). A template for cman_notify scripts can be found in the doc/ directory. OPTIONS
-f Run in the foreground (do not fork / daemonize). -d Enable debug output. November 2008 cmannotifyd(8)
