How to write at specific loaction in a file

[Pioneer]

Hi,

I have to write some text in a file keeping the previous content as it
is.

e.g.
$ cat file1
abc
qwe

I want the o/p as
$ cat file1
abc
123
qwe

I want to write 123 at second line. "open" command with > and >>
options either overwrites or appends at the end.

Thanks in advance
Pioneer

The perldocs are available online as well, at http://www.perldoc.com

What reply? Please quote appropriate context as has been customary for 20
years such that people have a chance to know what you are talking about.

but i dont have perldoc installed

Then I suggest you fix this broken Perl installation.

on our server.

Well, ok, as people don't develop on servers. Maybe you don't need to fix
it. But what about you development machines? Do they have broken
installations, too?

The true pioneer succeeds because he does not repeat the mistakes that
others already made.

Please quote some context in followups like everybody else does.

[ I think the reply was one referring you to the Perl FAQ ]

but i dont have perldoc installed on our server.

That is not an excuse for posting to the Perl newsgroup without
first checking the Perl FAQ.

You must check the Perl FAQ somehow, it is easier if you have
a properly installed perl, but it appears you will have to find
the Perl FAQ some other way.

Have you tried googling for it?
