String substitution

[kirk124]

Hi,

I use the following code to open a text file and update any strings such as "apple" to orange".

snippet:
open (IN,"c:\\data"
@lines = <IN>;
close IN;

@lines = map { s/\b$old_hostname\b/$new_hostname/sgi; $_ } @lines;
open (OUT,&quot;>c:\\data&quot || &quot;can't open data :$! &quot;;
print OUT @lines;

But now I must change any words such as &quot;data/applered&quot; or &quot;new_apple_dark&quot; to &quot; data/orangered&quot; &quot;new_orange_dark&quot;.

How can I alter my substitution to make it work.

--thanks kirk

Hi,

The strings &quot;data/applered&quot; or &quot;new_apple_dark&quot; are just example the strings might be any characters or noncharacters follow by the word apple like the following&quot;

bag/applered
bag/appleold
--/apple0123
!#&apple$%%

does something as simple as this work:

s/apple/orange/gi;

or are there other constraints? In your example, to specify word boundries, but didn't mention in your post, so I am a bit befuddled.

I am trying to update a text file.
I have to substitute every word that consists of the word &quot; apple&quot; with &quot;orange&quot;.

For example:

darkapplelite tapple &&%apple098 etc becomes

darkorangelite torange &&orange098 ...

Well, then I think that one should do it.

$_ = 'darkapplelite tapple &&%apple098';
s/apple/orange/gi;
print;

I assume the '&&[red]%[/red]apple098' to '&&orange098' is a typo.
