If you put your file content in a file called "hi.txt" then his is the command to obtain what you required:

[ramki@lindesk3 ramki]$ cat hi.txt | grep -i "ext"
telephoneNumber: 41827200 Extn: 7400

[ramki@lindesk3 ramki]$ cat hi.txt | grep -i "ext" | sed 's/ Extn/\nExtn/g'
telephoneNumber: 41827200
Extn: 7400

Thanks,

heres a guideline of what i think needs to be done.
have input file hi.txt and outputfile hi2.txt

read each line of input file and output to new file.
on each line do an awk:

eg.

cat hi.txt | awk '{print $1 " " $2 " " $3 " " $4 } '
telephone: 345345435 Extn: 4545

now u have four fields seperate.

then when $1 = "telephone:"
output $1 and $2 then next line
output $3 and $4.

and at the eof
mv hi2.txt to hi.txt

Code:

$ sed -i '/^telephoneNumber:/ s/Extn/\nExtn/' tel.txt

//Jadu

Code:

awk  '{
if($1=="telephoneNumber:" && $3=="Extn:")
printf("%s %s\n %s %s\n",$1,$2,$3,$4)
else
print
}' filename

thanks alot everyone,i got it working.
I appericiate the quick response of you guys.

Thanks...

Hope This should work

grep "Extn:" filename | awk '{printf("%s%s\n",$1,$2);printf("%s%s\n",$3,$4)}'
