Hi,
I have to parse 100's of files in a loop and replace a word called boston with a new word miami. I have to use korn shell scripting and I know grep, awk and also the looping part but I am not able to figure out how to implement the string replace part. I can vi each and every file but I want to automate this in a ksh using for loop. Appreciate your responces.
Thanks
Carl

ex: From:
cat file1.dat
city name is boston and country is USA.

To:
cat file1.dat
city name is miami and country is USA.

Like file1.dat, I have 100's of files in which I have to do string replace and preserve the same file name.

never mind, i figured out the solution. need to cat the files in a loop and pipe it to a sed to replace the word. such an easy implementation and it didnt strike me

But why do you need 'cat' and 'pipe' if sed can accept a file as argument.?? And still the sed 's output can be redirected to create a new file

Example:
