Question

I’ve a file with some text (8/9 lines) called abc.txt

I’m trying to replace a string called in pqr.xml with contents from above abc.txt file.

Can any one tell me how to do it?

I was trying with below command:

sed -i~ "s/ < /Server>/HERE HOW TO PASTE CONTENTS FROM abc.txt/g" pqr.xml

I am not sure about sed but with awk you might get what you are trying to achieve.

awk script:

#!/usr/bin/awk -f

{
# Loop thru each words in your file

    for (i=1;i<=NF;i++) 

# When the word is pqr.xml, we read your second file

        if($i~/pqr\.xml/) 
            {
                system("cat file2"); 

# We store the content of the file in a variable and print it

                getline a; 
                printf a; 

# For everything else we just print the word as is

            }else 
                printf $i" ";
                print "";
}

File1:

[jaypal:~/Temp] cat file
this is my pqr.xml

File2:

[jaypal:~/Temp] cat file2
