What do I do to get list of files that have tabs? How to do substitute the tabs with spaces?
Is there a way to do that in a perl script that traverse the directory structure and replace tabs with spaces?


my project has so many files it would be time consuming to do one by one!


Thanks
in advance!

Traverse the directory, open file and read each line. For each line perform tab replacement as below example
## Replace tabs with a single space
my $str = "1\t2\t3\t4 5 6";
print $str ."\n";
$str =~ s/\t/ /g;
print $str ."\n";

#!/usr/bin/perl
 
$dir = "path";
 
use File::Find;
find(sub{push(@files, $File::Find::name) unless -d}, $dir);
 
foreach $file (@files) {
        open(FILE, $file);
        foreach $line (<FILE>) { push(@file, $line); }
        close(FILE);
 
        $data = join("", @file);
        @file = ();
 
        $data =~ s/\t/ /g;
        open(FILE, "> $file");
        print FILE $data;
        close(FILE);
}
