Hello
Can anyone tell me if there is a
java api that duplicates the functionality provided in the Nawk utility? I am trying to retrieve Unix Server statisitics, reformat the output and load that file into Oracle. I am using the unix sar command to read a system accounting file (named sa24 created on Oct 24) located in /usr/adm/sa. I pipe the output to nawk and use the C printf program to format the output. I have a sample someone else wrote in Korn shell, but I do not know Korn shell and would like to do the same thing in a java program. Some manipulation that needs to be done to the output is delete lines with spaces, header lines and a row showing averages to load just the raw data (numbers) into each Oracle record.
Here is the syntax for what I described above.
sar -u -f sa24|nawk '{printf "%5s %5s %5s %5s %5s\n",$1,$2,$3,$4,$5}'\
Sample output:
SunOS cero 5.8 Generic_108528-13 sun4u
00:00:01 %usr %sys %wio %idle
01:00:00 17 7 40 36
..
{the output includes statistics for every hour}
....
23:00:00 2 7 68 23
Average 11 8 59 22
I found an api for Java that dupicates the printf C functionality at

Thank you
