Top Forums UNIX for Dummies Questions & Answers Print events from two lines with a common identifier Post 302824543 by rbatte1 on Friday 21st of June 2013 05:11:22 AM

So, just to get the logic right first:-
  • You want to get the start record of an alarm and grab the first five fields
  • You want to append the clear-alarm record fields 5 & 6
If this is true, then it depends on the volume of data as to weather it is easier to write a shell script with greps or a more complex awk

You could:-
  • Get a list of all the common identifiers then use grep to get those records and blend them together.
  • Split the record into two files, strip out the fields you don't want then use paste

There are probably plenty of other ways too. What are your thoughts on this?

NAME
alarm - schedule an alarm signal SYNOPSIS
#include <unistd.h> unsigned int alarm(unsigned int sec); DESCRIPTION
The alarm() function causes the system to generate a SIGALRM signal for the process after the number of real-time seconds specified by sec- onds have elapsed (see signal.h(3HEAD)). Processor scheduling delays may prevent the process from handling the signal as soon as it is generated. If seconds is 0, a pending alarm request, if any, is cancelled. Alarm requests are not stacked; only one SIGALRM generation can be scheduled in this manner; if the SIGALRM signal has not yet been gen- erated, the call will result in rescheduling the time at which the SIGALRM signal will be generated. The fork(2) function clears pending alarms in the child process. A new process image created by one of the exec functions inherits the time left to an alarm signal in the old process's image. RETURN VALUES
If there is a previous alarm request with time remaining, alarm() returns a non-zero value that is the number of seconds until the previous request would have generated a SIGALRM signal. Otherwise, alarm() returns 0. ERRORS
The alarm() function is always successful; no return value is reserved to indicate an error. ATTRIBUTES
