PIPE DROP PIPE DROP Syntax DROP: DROP Synonyms FIRST LAST 1 count MSGS LINES Stage Operands Synonym MSGS MSG LINES LINE Command Description The DROP stage enables you to specify how many messages or lines are to be discarded from the primary output stream. When the specified number of messages or lines are read from the input stream and discarded, all other messages or lines are copied to the primary output stream. Streams 72 Programming: Pipes Discarded messages or lines are passed to the secondary output stream, if connected. Stream Type Number Supported Input 1 Output 2 Termination Conditions DROP terminates when the input stream or both output streams disconnect. Operand Descriptions count Specifies the number of messages or lines on the input stream to be discarded. Valid values are in the range of 1 - 10,000,000. The default is 1. FIRST|LAST Specifies whether the messages or lines dropped are the first or last messages or lines in the stream. The default is FIRST. LINES Specifies that count is the number of lines within the input stream to be dropped. If LINES is not specified, DROP discards the number of messages indicated by count. MSGS Specifies that count is the number of messages within the input stream to be dropped.
Usage Notes DROP cannot be the first stage. Examples PIPE DROP Example: Discarding Messages with DROP The pipe in the following example takes the output of the NetView LIST " command, deletes the END OF STATUS DISPLAY line using the DROP stage, collects the results into a multiline message, and displays them. PIPE NETVIEW LIST " | DROP LAST 1 | COLLECT | CONSOLE The DROP stage buffers one message so that it can determine which is last. It then discards this last message. Notice that the order is important. If COLLECT preceded DROP, then DROP would have seen exactly one (multiline) message on its input stream. That entire message would have been dropped. Chapter 2.
