You missed the /d modifier.

Untested:

$b =~ s/chr(0x013)//;

Function calls do not interpolate.

Thanks "It work!!!"
Super.

\013 is octal. 0x0D = 13 = \015. Better to use \r if you mean carriage
return, though. And as Gunnar said, you need the d modifier:

$b =~ tr/\r//d;

You missed the /d modifier.

You missed the fact that \013 is in octal, not in hex.

And the OP may just have missed that hex "13" is not decimal 13, which
seems like a far more likely candidate to want to delete.

You missed the fact that \013 is in octal, not in hex.

Since you say that *I* missed, I have to ask: Is there a requirement to
cover the whole problem when you try to help here?

I didn't even consider the SEARCHLIST, but I know that you need the /d
modifier to erase characters with the tr() operator, and I chose to call
the OP:s attention to that. Shouldn't I have done so?

Well, you suggested that

tr/\013//d

would solve his problem of deleting the character hex "13", which it
doesn't.

If you don't solve the whole problem, be prepared for corrections.
