Q: File contents substitution

[Troll]

Hi,

I posted this in one of the other grps but have had no real luck yet. Sorry.

I need 2b able to change the contents of a file, ie. to substitute
occurences of 'one' to 'two'.
I have something like:
**************************
sub replace {
s/one/two/g;
}

open (INFILE, "+<test.txt") || etc...
while (<>) {
replace ();
}
**************************

Contents of test.txt are:
hello one
one ten one ten

What am I missing to make this work? I'd love to read the manual [like
someone has suggested] but by the time I get there it'll be next year...
Thanks in advance.

Then read the FAQ instead, it's short and sweet. perldoc -q 'line in a file'.

-q lets perldoc search the faq for keywords. See "perldoc perldoc" for the
whole story.

perldoc is a program that comes bundled with every
distribution of Perl.

You run it from a command line. If you used Unix
all of this would be obvious, so I'll assume you use
Windows. Go to the Start ->Programs->Accessories
menu and start "Command Prompt" to get a
command line window (Or Start -> Run -> cmd.exe)

-q is a command line switch and stands for "query"

[perldoc]

-q is a command line switch and stands for "query"

I alsways thought it stood for faQ (because -f was taken by something
more important).

You guessed right. Thanks Helgi.
