NAME
implog - IMP log interpreter SYNOPSIS
/usr/sbin/implog [ -D ] [ -f ] [ -c ] [ -r ] [ -l [ link ] ] [ -h host# ] [ -i imp# ] [ -t message-type ] DESCRIPTION
Implog is program which interprets the message log produced by implogd(8C). If no arguments are specified, implog interprets and prints every message present in the message file. Options may be specified to force printing only a subset of the logged messages. -D Do not show data messages. -f Follow the logging process in action. This flags causes implog to print the current contents of the log file, then check for new logged messages every 5 seconds. -c In addition to printing any data messages logged, show the contents of the data in hexadecimal bytes. -r Print the raw imp leader, showing all fields, in addition to the formatted interpretation according to type. -l [ link# ] Show only those messages received on the specified ``link''. If no value is given for the link, the link number of the IP protocol is assumed. -h host# Show only those messages received from the specified host. (Usually specified in conjunction with an imp.) -i imp# Show only those messages received from the specified imp. -t message-type Show only those messages received of the specified message type. SEE ALSO
imp(4P), implogd(8C) BUGS
Can not specify multiple hosts, imps, etc. Can not follow reception of messages without looking at those currently in the file. 4.2 Berkeley Distribution November 16, 1996 IMPLOG(8)
