Re: Failboat -- An Emotionally Disturbed Tool For Checking NetBackup Client Coverage

Thanks for contributing. I mean that earnestly.

Please forgive my one small Unix gripe, however. There is no need to pipe grep output to awk. awk will do it all.

me@mybox:~/sandbox
$ cat data.txt
bob 21 xyz
sam 8 uuu
bob 90 fff
sue 12 qaz
bob 99 har
me@mybox:~/sandbox
$ grep bob data.txt | head -1 | awk '{print $2}'
21
me@mybox:~/sandbox
$ awk '/bob/ {print $2; exit}' data.txt
21

I was referring to this line of yours:

$lastValidBackupTime=`/usr/openv/netbackup/bin/admincmd/bpcatlist -cli
+ent $client 2>&1 | grep $client | head -n1 | awk '{print $2}'`;

That is your problem with it, Really? How about using Perl to do that, since we are doing this in a Perl program: `open my $PIPE, '-\|', "/usr/openv/netbackup/bin/admincmd/bpcatlist -cli +ent $client 2>&1" or die "Cannot open pipe from 'bpcatlist' $!"; while ( <$PIPE> ) { next unless /$client/; $lastValidBackupTime = ( split )[ 1 ]; last; } close $PIPE or warn $! ? "Error closing 'bpcatlist' pipe: $!" : "Exit status $? from 'bpcatlist'";` [download]	[reply] [d/l]

Besides, I suspected someone more clever and skilled at Perl such as you would respond with appropriate Perl syntax, and I was still able to spread the message of usless use of grep. So it looks like a win-win situation to me.	[reply]

(Sorry, been posting Anonymously..deh) I could have done it in straight Perl, but it's kind of clumsy and elaborate by comparrison, considering i'm not really doing anything but invoking an external command.	[reply]

Oh, I know. That backticked statement was just off the top of my head. I'm aware that awk is perfectly capable of doing what i've described ala piping. Sadly, i've never used awk enough to know how to use it properly in this context.	[reply]
