资 源 简 介
This software is a text filter for Linux/Unix environments. It processes text lines passed in from stdin and forwards most of them to stdout/stderr.
Text lines which contain the carriage return character (cr) are often used by software to print progress information on a text console. They repeatedly update a single line on screen with the latest status. One example of such a software is the video encoding software mencoder.
Some tools update the status very often, e.g. mencoder may do so several hundred times per second. Such output can be very disturbing when running software over a remote terminal connection with low bandwidth. Completely filtering such output is often not an opttion for jobs running over an extended period of time, because a limited amount of progress information is still desirable.
The crswallow filter can limit status output to a single update in a given time interval, for example once per second.
