Hi,

Thanks for ur reply..Once string format is matched i want to print same line and next four lines in a seperate file and again i need to search for string format in a file.
Whenever string format is matched i need to print same line and next four lines in a seperate output file.
Please provid the sample script using shell scripting or PERL.

try this

 
awk '/pattern/{print};c-->0;/pattern/{c=4}'  filename > outfile

Another form of vidyadhar85 solution :

 awk '/pattern/{print;c=4;next};--c>0'  filename > outfile
