Re^2: Filtering passwords from the output of a script

Three issues:

It is word-buffered. It will only output when whitespace is received.
It won't always work if the password has a space in it.
I imagine that reading a byte at a time (when more than a byte is available) is much slower than reading a chunk of bytes.

See Re^3: Filtering passwords from the output of a script.

By the way, binmode might be required. I remember having problems when attempting to read characters (as opposed to bytes) using sysread, but the details escape me.

Good points, although /\s/ actually also matches newline and carriage return. As a sheer stroke of fortune, in my current application a restriction against using spaces or non-ASCII characters in passwords is appropriate. Also, I don't have to worry too much about efficiency, my logs only arrive at a few hundred bytes per second typically. Thanks again!	[reply]
