A short look to CPAN brings out https://metacpan.org/pod/File::Inplace what looks to do what OP wants. Honestly I never used, and it can be that it has also a performance problem, but for at least I looked to it's source code and it implements it via a temporary file without saving the whole file.

Gigantic file size processing error
Hi, We have file size of huge size 500MB, Need to Manipulate the file, some replacement and then write the file, I have used File::slurp and works for file size of 300MB (Thanks Uri) but for this huge size 500MB it is not processing and come out with error. I have also used Tie::file module same case as not processing, any guidance. regards Manikandan
Re: Text Manipulation
Dear zavierz
probably you can try this
$I=~s/^(Article\s+[0-9]+\s+[\A-Z_a-z]+\S)/\\subsection*{$1}/g;
print $I;

Hi, I am trying to modify a LaTex file which is plain text.
The file contains lines similar to the following, but each line is
followed by text, so that:
Article 1 Cats
Article 2 Dogs
Article 3 Fish
Article 4 Ferrets
etc.
I would like to modify the file so that each referenced line is
changed as follows:
\subsection*{Article 1 Cats}
\subsection*{Article 2 Dogs}
\subsection*{Article 3 Fish}
\subsection*{Article 4 Ferrets}
Here's code which was suggested to me, but when I execute it I'm
returned to the command line and nothing happens:
#!/usr/bin/perl
s/^(Article\s+[0-9]+\s+\N*\S)/\\subsection*{$1}/gm
I called this script Article and saved it as article.pl
The usage then was $perl article.pl oldfile.tex newfile.tex
and I got the following error message:
Missing braces on \N{} at article.pl line 2, within pattern
Nested quantifiers in regex; marked by -- HERE in m/^(Article\s+[0-9]+
\s+* -- HERE \S)/ at article.pl line 2.
So I added braces as follows: \{N}
I ran the script again; there was no error message but no newfile.tex
either.
I then ran the program as follows:
$perl article.pl oldfile
And the response is the command prompt and the file hasn't been
modified.
any suggestions?

error at using config::ini
Dear all
Please see the below code, i am in course of studying Configuration in perl,
when i came across writing a small code, a error message was:
Can't locate Config/IniFiles.pm in @INC (@INC contains: C:/Perl/lib C:/Perl/site

But my other programs works fine. The above module is found at local ie.,

my $file= Setup1.ini;
my $ini=Config::IniFiles-new(-file=$file)or die could not open

my $email=$ini-val('Network', 'email');
print check $email\n;

Re: error at using config::ini
If i am wrong please correct me, i presume that config::ini must be installed in perl by while installing, if not what is the option for checking that config::ini is installed or not.

Re: perl
Dear all Earlier i did not see the error message properly sorry! I found my apache installed in the C:\Program Files\Apache Group\Apache2, Is that,it is correct or it should be read as C:\Program Files\Apache2\ Please read my error message: [error] client [127.0.0.1] OS3 The system cannot specified the path specified: Couldn't create child process: 72003 : first.pl [error] client [127.0.0.1] OS3 The system cannot specified the path specified: C:\Program Files\Apache Group\Apache2\cgi-bin\first.pl regards mani That means that it is looking in that location for the file and it can't find the file there. Did you try running perl c:\programfiles\apahce2\cgi-bin\first.pl? That will execute the script if the script is there (ie the path is correct). If that does not work, then there is nothing wrong with Apache. It's just being told to look for a file where none exist. If that does work, and it runs your script, then there is something wrong with Apache. Try it out.
