Hi,
I was wondering if pipes ("|"), or rather the command that follow them, know when they're supposed to wait for all the data?

WORDWRAP(3) 1 WORDWRAP(3)wordwrap - Wraps a string to a given number of charactersSYNOPSIS
string wordwrap (string $str, [int $width = 75], [string $break = "0], [bool $cut = false])
DESCRIPTION
Wraps a string to a given number of characters using a string break character.
PARAMETERS
o $str
- The input string.
o $width
- The number of characters at which the string will be wrapped.
o $break

o $cut
- If the $cut is set to TRUE, the string is always wrapped at or before the specified $width. So if you have a word that is larger
than the given width, it is broken apart. (See second example). When FALSE the function does not split the word even if the $width
is smaller than the word width.
