if yes.. how?

I need to search for some 2-3 mail addresses in multiple files and delete all those... and instead of them.. I need to insert a new mail id...( these are also other emails in that list .. which sud not be affected )

is sed 'll be a good choice...??
or is there any other way to make it more effective...

Thnks
Are all those email ids in a single line ? Or one per line ? Will you replace all those 3 mail ids with just 1 mail id or will you replace each one with 1 mail id ?

If one per line, then
Code:
sed -i -e "/john\@doe.com/d" -e "/foo\@bar.com/d" file.txt file1.txt

If it all-in-one-line or just scattered all over the place, then
Code:
sed -i -e "s/john\@doe.com//g" -e "s/foo\@bar.com//g"  file.txt file1.txt

NAME
exo-open - Open URLs and launch preferred applications SYNOPSIS
exo-open [[url]...] exo-open --launch [category] [[parameter]...] DESCRIPTION
exo-open is a command line frontend to the Xfce Preferred Applications framework. It can either be used to open a list of urls with the default URL handler or launch the preferred application for a certain category. INVOCATION
exo-open either takes a list of URLs and tries to open each of them using the default handler, or, when using the --launch tries to launch the preferred application for a certain category, optionally passing any number of parameters to the application. Options -?, --help Print brief help and exit. -v, --version Print version information and exit. --working-directory directory When using the --launch option and this option is specified as well, the application will be run in the given directory. This is primarily useful when running the preferred TerminalEmulator from another application and you want the command in the terminal window to be run in a specific directory. --launch category parameters... Launch the preferred application for the given category with the optional parameters..., where category is either WebBrowser, MailReader, TerminalEmulator or FileManager. If you do not specify the --launch option, exo-open will open all specified URLs with their preferred URL handlers. Else, if you specify the --launch option, you can select which preferred application you want to run, and pass additional parameters to the application (i.e. for TerminalEmulator you can pass the command line that should be run in the terminal). COMPOSING EMAILS
exo-open allows users and developers to open the preferred email composer from the command line by simply invoking exo-open mailto:USER@HOST.TLD. This will open the composer window with USER@HOST.TLD as the recipient. This syntax is supported by all MailReaders. In addition the MailReaders that ship as part of libexo also support extended mailto:-URIs (but be aware that user-defined mailers do not necessarily support this), which allows you to also specify default values for the subject and the body of the mail, add additional recipients (both Cc: and To:) and attach files to emails. For example mailto:foo@foo.org?cc=bar@bar.org&subject=Foo&attach=/foo/bar.txt tells the composer to start an email to foo@foo.org and bar@bar.org with Foo in the subject and the file /foo/bar.txt attached to the message.
