Hi,
I'm a perl newbie and would like to ask this question here.
Let's say I have the following code. Trying to check the disk space,
it's to truncate the percent sign % from the df -k output, compare the
percentage field to see if it's bigger than 90%, and grasp only those
lines that are and push those to an array @df. But how can I add the
percentage sign back to the percentage field on each line for the
proper output? I put down ??????? as below to find out what regexp
needs to be there in the below.
$percent=90;
open(DFOUT, "/usr/bin/df -k|");
while (<DFOUT>) {
next if ($_ =~ /Filesystem/i);
s/\%//; # to remove the percent sign for
comparison
if ( (split)[4] >= $percent ) {
???????
push(@df, $_);
}
}
print "@dfoutput\n";
I appreciate your help very much!
Thank you.
