I need to modify one of my data files...

can any one tell my how i could insert a word in a string:

for example:  

I have a list file containing the following email addresses

pe...@new-york.abc.com
sa...@new-york.nbc.com

and son on..

I need to insert "nycsu2" between the symbol @ and new-york followed by
a dot (.)   giving me the final outcome as follows:

pe...@nycsu2.new-york.abc.com
sa...@nycsu2.new-york.nbc.com

can i do that using grep or awk or both..  any and all the help will be
greatly appreciated:

my email address is :

il...@nycsu2.new-york.sl.slb.com
or
il...@new-york.sl.slb.com
or
il...@ycvax.york.cuny.edu

Hi,

You will get about 20 different answers to this. Here's one...

sed -e 's/@/@nycsu2./' input-file >output-file

#cat file | sed 's/new-york/nycsu2.new-york/g' > newfile

Then you can examine the newfile and if it is correct, copy it over
the original file.

Try "sed '...@new-york.abc.com/...@nycsu2.new-york.abc.com/ < srcfile"

OK.
First vi your file, when it opens press : to enter command mode.  The : prompt will appear in the bottom left hand corner of you screen.  Now
just type in the following  -

g/@/s//@nycsu2./g <RETURN>

Don't forget to save your changes -

:wq
