Code shared on permonks by choroba.

#!/usr/bin/perl use warnings; use strict;


use Text::Table;

use constant CAPACITY => 3;

my @lines = `df -hP`; my $header = shift @lines; # Do not create two columns for "Mounted" and "On" $header =~ s/Mounted /Mounted_/; my $table = Text::Table->new(split ' ', $header); { no warnings 'numeric'; # Ignore % signs @lines = sort { $a->[CAPACITY] <=> $b->[CAPACITY] } map [split ' ', $_], @lines; } $table->load(@lines); print $table;

There is one i made it working as below;

############################################# #!/usr/local/bin/perl


    # Use either -h or -k flag or leave it blank for default (-k)

    # -h for human-readable size output

    # -k for 1k-block output

    $flag = "-h";

    @df = `df $flag`;
    print "Content-type: text/htmln\n";

    print "
\n";

    print "
\n";
    print "
\n";
    if ($flag eq "-h") {

        print "
\n";

    }

    else {

        print "
\n";

    }
    print "
\n";

    print "
\n";

    print "
\n";

    print "
\n";

    print "
\n";
    foreach $line (@df) {

        next if ($line =~ /Filesystem/);
        ($fsystem,$blocks,$used,$avail,$capacity,$mounted) = split(/\s+/,$line);
        print "fsystem is $fsystem\n";

        print "blocks is $blocks\n";

        print "used is $used\n";

        print "avail is $avail\n";

        print "capacity is $capacity\n";

        print "mounted is $mounted\n";
    ($number,$sign) = split(/%/,$capacity);

    if ($number < 60) {
        print "

\n";

    }

    elsif (($number >= 60) && ($number < 90)) {
        print "

\n";

    }

    else {

        print "
\n";

    }

Df command usage

scmgalaxy K — Fri, 08 Dec 2017 04:45:49 +0000

rajeshkumar created the topic: df command usage
Filesystems using more than 90% capacity

df -hP | awk '{x=$5;sub ("%","",x)}x>75' df -h | awk '{if(NF==1){x=$0;getline;if(int($4)>90)print x,$0}else if(int($5)>90) print}'

ssh -q rajesh 'df -hP' | awk '{x=$5;sub ("%","",x)}x> 30' ssh -q rajesh 'df -h' | awk '{if(NF==1){x=$0;getline;if(int($4)>60)print x,$0}else if(int($5)>60) print}'

Error: df: unknown option: P Usage: df [-F FSType] [-abeghklntVvZ] [-o FSType-specific_options] [directory | block_device | resource]

Solution:

May be your solaris version is not supporting P options. Check it out without using -P.

df output filter based on Mounted on and Capacity

df -kh | awk '/\/export/ && int($5) >= 90'

Here Capacity – 90%
Mounted on – \export
df -kh | \ # Pipe the output of df to awk
awk ‘ # Start the awk script
/\/mnt/ \ # Grep for pattern(first condition)
&& \ # add a second condition (and)
int($5) >= 85 \ # Check if integer of $5 is greater that 85(second condition)
‘ # End awk script

Df Output to one line

ssh -q $server 'df -hP | cat' 2>&1
