Shell Programming and Scripting

I have a huge collection of text files on my computer. These files contain lots of text in them. The files look like this.

Example 1:

Code:

This is a test file. This is an email address: abc.yahoo.com. This is another line.

Example 2:

Code:

This is another file. The person can be contacted at cdc.gmail.com.

I want to delete all the e-mail addresses from all the files. The problem is the e-mail addresses are not all same. Some are Yahoo, some are Gmail and some from .edu domain etc. So, I cannot find out the specific pattern.

Currently, I do it manually and use this command

Code:

ls -1 *.dat | while read page
do
cat $page | sed -e '/@yahoo.com/g' $page>$page.txt
done

But it takes lots of efforts to do it one at a time. Any ideas how I can get rid of all e-mail addresses at one go. I am using Linux with BASH.

probably this may help

Code:

 
DEVENS /oravl01/oracle/shipraa > sed 's/[A-Za-z0-9]*\.[A-Za-z0-9]*\.com//g' sample
This is a test file. This is an email address: . This is another line
This is another file. The person can be contacted at .
DEVENS /oravl01/oracle/shipraa >

Now, e-mails could be of variety types. I am not that expert in such scripting stuffs but from your code, I could come up with this

Code:

sed 's/[A-Za-z0-9]*\.[A-Za-z0-9]*\@[A-Za-z0-9]*\.com//g' test.txt

So, if somone has e-mail as abc.cde@yahoo.com then it will work.

Now, I'll feed in other rules for addresses like these
abc_cse@gmail.com
cde-abc@work.edu
