in reply to Strip bad characters from a string

You want tr. 
$_ = <<STOP;
'foo' is in single
quotes, "bar" is in
double quotes, and
there are carriage returns
between
STOP

tr/'"\n//d;

print;

RE: Strip bad characters from a string

    Instead of just stripping them, how do I make a ' into a \' and " into a \". I tried using your example and adapting it but the result was \\\\\\\\\\\\\\\\\\\\\\\\\\\\' because it keeps looping just looking for the single character. Any ideas appreciated. Ian.

      Try 
      s#(['"])#\\$1#g;

      Result (using the same string that I used the first time): 
      \'foo\' is in single
quotes, \"bar\" is in
double quotes, and
there are carriage returns
between
