The regular expression engine can do this for you already! :-)

local $_ = "this is an\b\b\b correct\b\b\b\b\b\b\b\borrect usage";
s/(.[\b])//;
print $_;

Update: I realized my error and changed \\b to [\b]. Which should now work.

No, you are replacing backslash followed by 'b' as shown below. `local $_ = "this \\b is an\b\b\b correct\b\b\b\b\b\b\b\borrect usage"; print "$_\n\n"; s/(.\\b)//g; print $_;` [download] /-\	[reply] [d/l]
