Read from one file-Replace a pattern in another with the current one
Hi Friends,

I have a text file like this

Code:
cat main.txt

I like this website

cat website > new_website

grep website > hello_website

Code:
cat replace.txt

hello
unix
apple

Now, for each line read in 2.txt, I want the pattern "website" in 1.txt to be replaced with it. Basically, I will be getting wc number of files in 2.txt

So, my final output files will be

Code:
cat main1.txt

I like this hello

cat hello > new_hello

grep hello > hello_hello

Code:
cat main2.txt

I like this unix

cat unix > new_unix

grep unix > hello_unix

Code:
cat main3.txt

I like this apple

cat apple > new_apple

grep apple > hello_apple

I got an ide of the following, but I think I am missing something

Code:
for i in `cat replace.txt`; do sed '/website/$i/s';done

But, I am having trouble on listing the files and updating the file numbers.

Thanks in advance.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
