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.

nos-tun

NOS-TUN(8)						    BSD System Manager's Manual 						NOS-TUN(8)

NAME

     nos-tun -- implement ``nos'' or ``ka9q'' style IP over IP tunnel

SYNOPSIS

     nos-tun -t tunnel -s source -d destination -p protocol_number [source] target

DESCRIPTION

     The nos-tun utility is used to establish an nos style tunnel, (also known as ka9q or IP-IP tunnel) using a tun(4) kernel interface.

     Tunnel is the name of the tunnel device /dev/tun0 for example.

     Source and destination are the addresses used on the tunnel device.  If you configure the tunnel against a cisco router, use a netmask of
     ``255.255.255.252'' on the cisco.	This is because the tunnel is a point-to-point interface in the FreeBSD end, a concept cisco does not
     really implement.

     Protocol number sets tunnel mode.	Original KA9Q NOS uses 94 but many people use 4 on the worldwide backbone of ampr.org.

     Target is the address of the remote tunnel device, this must match the source address set on the remote end.

EXAMPLES

     This end, a FreeBSD box on address 192.168.59.34:

	   nos-tun -t /dev/tun0 -s 192.168.61.1 -d 192.168.61.2 192.168.56.45

     Remote cisco on address 192.168.56.45:

	   interface tunnel 0
	   ip address 192.168.61.2 255.255.255.252
	   tunnel mode nos
	   tunnel destination 192.168.59.34
	   tunnel source 192.168.56.45

AUTHORS

     Nickolay N. Dudorov <nnd@itfs.nsk.su> wrote the program, Poul-Henning Kamp <phk@FreeBSD.org> wrote the man-page.  Isao SEKI
     <iseki@gongon.com> added a new flag, IP protocol number.
