crswallow (sysutils/crswallow) Add to my watchlist 0

crswallow 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. 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. The crswallow filter can limit status output to a single update in a given time interval, for example once per second.
