Modifying bash script to take each line in a file and execute command
I need to modify a bash script to to take each line in a file and execute command. I currently have this:

Code:
#!/bin/bash if [ -z "$1" ] ; then echo "Lipsa IP"; exit; fi i=1 ip=$1 while [ $i -le `wc -l pass_file | awk '{print $1}'` ] ; do if [ -n "$ip" ]; then rand=`head -$i pass_file | tail -1` user=`echo $rand | awk '{print $1}'` pass=`echo $rand | awk '{print $2}'`  CMD=`ps -eaf | grep -c mysql`  if [ "$CMD" -lt "50" ]; then ./mysql $ip $user $pass & else sleep 15 fi i=`expr $i + 1` fi done

The password file is in format and named "pfile":

Code:
username password
       username2 password2
              username3 password3

The intranet hosts file is in this format (line-by-line) and named "hlist":

Code:
192.168.0.1
192.168.0.2
192.168.0.3

Any suggestions how I can do this? I really have no clue.

---------- Post updated at 04:50 PM ---------- Previous update was at 04:46 PM ----------

Code:
192.168.0.1
192.168.0.2
192.168.0.3

For some reason I cannot edit the above post. The host file is in this format, line-by-line.

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

NAME

       tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target

SYNOPSIS

       tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]

DESCRIPTION

       Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
       iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.

       The  script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
       tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.

EXAMPLES

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82

       Create a target that uses /dev/sdb1 and allows connections from any initiator:
       tgt-setup-lun -d /dev/sdb1 -n my_target

       Display help:
       tgt-setup-lun -h
