Data insert predefine text in front and on a loop
Hi Experts,

I wish to insert predefined text in front of every line and this needs to be in a loop because it is always expanding.

44444444

55555555
77777777
88888888
00000000

[...]

To be Inserted :
a=
b=
c=
d=

After :
a=11111111
b=22222222
c=33333333
d=44444444

a=55555555
b=77777777
c=88888888
d=00000000

[...]

I've been searching and trying but to no avail Smilie

Thank you in advance,

ipsec_klipsdebug

IPSEC_KLIPSDEBUG(5)						  [FIXME: manual]					       IPSEC_KLIPSDEBUG(5)

NAME

       ipsec_klipsdebug - list KLIPS (kernel IPSEC support) debug features and level

SYNOPSIS

       ipsec klipsdebug
	     cat/proc/net/ipsec_klipsdebug

DESCRIPTION

       /proc/net/ipsec_klipsdebug lists flags that control various parts of the debugging output of KLIPS and MAST, two of the IPsec stacks
       supported by Libreswan. At this point it is a read-only file.

       A table entry consists of:

       +
	   a KLIPS debug variable

       +
	   a '=' separator for visual and automated parsing between the variable name and its current value

       +
	   hexadecimal bitmap of variable's flags.

       The variable names roughly describe the scope of the debugging variable. Currently, no flags are documented or individually accessible yet
       except tunnel-xmit.

       The variable names are:

       tunnel
	   tunnelling code

       netlink
	   userspace communication code (obsolete)

       xform
	   transform selection and manipulation code

       eroute
	   eroute table manipulation code

       spi
	   SA table manipulation code

       radij
	   radij tree manipulation code

       esp
	   encryptions transforms code

       ah
	   authentication transforms code

       rcv
	   receive code

       ipcomp
	   ip compression transforms code

       verbose
	   give even more information, beware this will probably trample the 4k kernel printk buffer giving inaccurate output

       All KLIPS debug output appears as kernel.info messages to syslogd(8). Most systems are set up to log these messages to /var/log/messages.

EXAMPLES

       debug_tunnel=00000010.

       debug_netlink=00000000.

       debug_xform=00000000.

       debug_eroute=00000000.

       debug_spi=00000000.

       debug_radij=00000000.

       debug_esp=00000000.

       debug_ah=00000000.

       debug_rcv=00000000.

       debug_pfkey=ffffffff.

       means that one tunnel flag has been set (tunnel-xmit), full pfkey sockets debugging has been set and everything else is not set.

FILES

       /proc/net/ipsec_klipsdebug, /usr/local/bin/ipsec
