This will work for a line, maybe more details will help me...

replace.sh:
Code:
#!/usr/bin/awk -f
FNR==1 { fnum++ }
/^HEADER$/ {h=1;l=0}
h {l++}
l==3 && fnum==1 { p1=$0; next }
l==3 && fnum==2 { print p1; next }
fnum==2 { print $0 }

Code:
[mute@geek ~/test]$ cat fileA
HEADER
some kinda of data aAAaaa
this is the new data aaAAAA
more data etc aaaa

[mute@geek ~/test]$ cat fileB
HEADER
some kinda of data in BBBB
this is the old data bbBBBb
more data etc bBBbBB

[mute@geek ~/test]$ ./replace.sh fileA fileB

NAME
safenet - Driver for SafeNet compatible UPS equipment NOTE
This man page only documents the hardware-specific features of the safenet driver. For information about the core driver, see nutupsdrv(8). SUPPORTED HARDWARE
This driver supports UPS equipment which can be controlled via SafeNet v1.0 for Windows (serial interface only). EXTRA ARGUMENTS
This driver supports the following optional settings in the ups.conf(5) file: manufacturer=value Autodetection of this parameter is not possible yet (and it probably never will be). Therefore, this user-defined string accepts any name. The default is unknown. modelname=value Like manufacturer above. The default is unknown. serialnumber=value Like manufacturer above. The default is unknown. ondelay=value Time to wait before switching on the UPS (minutes). Defaults to 1 minute. offdelay=value Time to wait before shutting down the UPS (seconds). Defaults to 30 seconds. UPSCMD
This driver supports some instant commands (see upscmd(8)): test.battery.start Start UPS self test test.battery.stop Cancel UPS self test test.failure.start Start simulated power failure test.failure.stop Cancel simulated power failure beeper.enable Enable the UPS beeper beeper.mute Temporarily mute the UPS beeper beeper.toggle Toggle the UPS beeper shutdown.return Turn off the load and wait for the power to return. Uses the timer defined by offdelay. shutdown.reboot Turn off the load and return. Uses the timers defined by offdelay and ondelay. KNOWN PROBLEMS
If you run the shutdown.return command with mains present, the output may stay on or switch off and not back on again. The shutdown.reboot command will unconditionally switch on the load again (with or without mains present). If the driver is called with the -k option (or through upsdrvctl shutdown) it tries to detect which command should be used in an attempt to stay off until mains is present again or to cycle the output if the power returned in the mean time. This isn't bullet-proof, and you should be prepared that the power will either not be shutdown, or that it doesn't return when the power comes back. AUTHOR
