^G is a bell character (\a). That's not a platform issue, AFAIK.
Anyway, in response to this thread I wrote Perl scripts that seem to
work as replacements for dos2unix and unix2dos.
dos2unix.pl:
#!/usr/bin/env perl
use strict;
use warnings;
use File::Copy "cp";
use File::Copy "mv";
use File::Temp qw{ tempfile };
if(@ARGV == 0)
{
print STDERR "Usage: dos2unix.pl file...";
exit 1;
}
for my $in_fn (@ARGV)
{
open my $in_fh, "<", $in_fn or die "Failed to open '$in_fn': $!";
my($out_fh, $out_fn) = tempfile() or
die "Failed to open temporary file: $!";
while(my $line = <$in_fh>)
{
$line =~ s/\cM//g;
print { $out_fh } $line;
}
close $in_fh or die "Failed to close '$in_fn': $!";
close $out_fh or die "Failed to close temporary file '$out_fn': $!";
my $backup = "$in_fn.orig";
die "Backup file '$backup' already exists! Aborting..." if -e $backup;
cp $in_fn, "$backup" or die "Failed to backup '$in_fn': $!";
mv $out_fn, $in_fn or die "Failed to replace '$in_fn': $!";
unlink "$backup" or
die "Failed to unlink backup file '$backup': $!";
}
__END__
unix2dos.pl:
#!/usr/bin/env perl
use strict;
use warnings;
use File::Copy "cp";
use File::Copy "mv";
use File::Temp qw{ tempfile };
if(@ARGV == 0)
{
print STDERR "Usage: unix2dos.pl file...";
exit 1;
}
for my $in_fn (@ARGV)
{
open my $in_fh, "<", $in_fn or die "Failed to open '$in_fn': $!";
my($out_fh, $out_fn) = tempfile() or
die "Failed to open temporary file: $!";
while(my $line = <$in_fh>)
{
$line =~ s/\cJ/\cM\cJ/g;
print { $out_fh } $line;
}
close $in_fh or die "Failed to close '$in_fn': $!";
close $out_fh or die "Failed to close temporary file '$out_fn': $!";
my $backup = "$in_fn.orig";
die "Backup file '$backup' already exists! Aborting..." if -e $backup;
cp $in_fn, "$backup" or die "Failed to backup '$in_fn': $!";
mv $out_fn, $in_fn or die "Failed to replace '$in_fn': $!";
unlink "$backup" or
die "Failed to unlink backup file '$backup': $!";
}
__END__
I was going to suggest dos2unix to solve half of this problem (hadn't
seen ^G before). In searching for a Perl driven solution I installed
the 'tofrodos' package on my new Debian 'squeeze' server to try to
integrate it with Perl. After installing it I couldn't find any of the
unix2dos/dos2unix variants on my system. :( I guess I ended up writing
simplified versions in Perl. At least they seem to work so I added
them to my PATH. :)
Thank you, Shlomi Fish, for your post. :) That lead me to learn a
little something new (as usual).
