Hi
This may help you

Code:
 
sed 's/pattern1/pattern2/g' filename > filename2

above command will replace pattern1 by inserting patter2.
also g is for global replacement if you want to replace only one occurance then use
Code:
 
sed 's/pattern1/pattern2/1' filename > filename2


Thanks
SHa

NAME
acctmerg - merge or add total accounting files SYNOPSIS
/usr/lib/acct/acctmerg [-a] [-i] [-p] [-t] [-u] [-v] [filename] ... DESCRIPTION
acctmerg reads its standard input and up to nine additional files, all in the tacct format (see acct.h(3HEAD)) or an ASCII version thereof. It merges these inputs by adding records whose keys (normally user ID and name) are identical, and expects the inputs to be sorted on those keys. OPTIONS
-a Produce output in ASCII version of tacct. -i Produce input in ASCII version of tacct. -p Print input with no processing. -t Produce a single record that totals all input. -u Summarize by user ID, rather than by user ID and name. -v Produce output in verbose ASCII format, with more precise notation for floating-point numbers. EXAMPLES
Example 1: Using the acctmerg command. The following sequence is useful for making "repairs" to any file kept in this format: example% acctmerg -v <filename1>filename2 Edit filename2 as you want: example% acctmerg -i <filename2>filename1 ATTRIBUTES
