sorta stupid because a lot of tools out there implement this.. i wanted to write my own just out of boredom i suppose. give the script a directory, what string to search in files for, and what string to replace it with.. and off it goes
however.. it does all this, except make any changes to the files. heh.
was wondering what blatantly obvious thing i forgot (sometimes its the most obvious that escapes people)
can you find it? :)
#!/usr/bin/perl
use Getopt::Std;
getopt("d:s:r:");
print "dir: $opt_d search for: $opt_s replace with: $opt_r\n";
print "Is the above info correct? y/n: ";
$confirmation = <>;
if ($confirmation =~ /y/i) {
opendir(DIR, $opt_d) or die "Couldn't opendir $opt_d\n";
while (defined($file = readdir(DIR))) {
next if $file =~ /^\.\.?$/; # skip . and ..
open(FILE, "$opt_d/$file") or die "Couldn't open $file
+: $!\n";
while (defined($line = <FILE>)) {
chomp $line;
if ($line =~ /$opt_s/) {
$line =~ s/$opt_s/$opt_r/;
print "changed $opt_s to $opt_r in $fi
+le\n";
}
}
close(FILE);
}
closedir(DIR);
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
