help regarding bdf output shell script !!!!

Pravin Salgaonkar — Fri, 16 Nov 2007 08:56:38 GMT

Hi,
I have written a funtion which taken bdf output and put's in a file.
The idea is to get all areas greater than 80% and echo the same on the system once they have reached 80 % limit. However the script I have written fails with the error.

The script is :-

======================================
output ()
{/usr/bin/bdf -l |awk '$0 !~ /^F/' |awk '{print $5"\t" $6}'| sed 's/'%'/''/' >/tmp/bdflist}

panic ()
{while read percent dir
do
if [[ $percent -ge 80 ]]
then
echo "File syste Full - `hostname`:$dir is at $percent%"
fi
done} < /tmp/bdflist
output
panic
===========================================
+ awk $0 !~ /^F/
+ awk {print $5"\t" $6}
+ sed s/%//
+ 1> /tmp/bdflist}
./test[8]: Syntax error at line 9 : `do' is not expected.

Please assist in resolving the same.
Thanking you in advance

here is a simple script i use written in perl. feel free to change it up.

$mailto = 'some@email_addr.com';
$hostname = `hostname`;
@mounts = `bdf`; #puts bdf info into seperate array elements

foreach (@mounts){
if ($_ =~ /100%|9[0-9]|8[0-9]%/) {
$fs = $';
chop $fs;
$mesg .= "$fs is at $&.\n";
}
}

if ($mesg) {
`echo "$mesg" | mailx -s "$hostname Filesystem Warning" $mailto`;
}

output ()

/usr/bin/bdf -l |awk '$0 !~ /^F/' |awk '{print $5"\t" $6}'| sed 's/'%'/''/' >/tmp/bdflist
}

panic ()
{
cat /tmp/bdflist | while read percent dir
do
if [[ $percent -ge 80 ]]
then
echo "File syste Full - `hostname`:$dir is at $percent%"
fi
done
}
output

noticed a mistake

($_ =~ /100%|9[0-9]|8[0-9]%/)

should be

($_ =~ /100%|9[0-9]%|8[0-9]%/)

Try:

/usr/bin/bdf -l |awk '$0 !~ /^F/' |awk '{print $5"\t" $6}'| sed 's/'%'/''/'|
while read percent dir
do
if [[ $percent -ge 80 ]]
then
echo "File syste Full - `hostname`:$dir is at $percent%"
fi
done

Hi:

The simple fix, is to place the curly braces for each function on a line by themselves:

...
output ()
{
/usr/bin/bdf -l |awk '$0 !~ /^F/' |awk '{print $5"\t" $6}'| sed 's/'%'/''/' >/tmp/bdflist
}
panic ()
{
while read percent dir
do
if [[ $percent -ge 80 ]]
then
echo "File syste Full - `hostname`:$dir is at $percent%"
fi
done
} < /tmp/bdflist
output
panic

...

This script could/should be rewritten to eliminate using temporary files (pipe output to the 'read') and should let ONE 'awk' do the work of matching and extracting (consider using 'awk's 'split').

For a simple script like this, in-lining your code like Geoff suggested is probably a more-readable approach.

Regards!

Hi,

include a shell interpreter and a few newlines:

#!/usr/bin/sh
output ()
{
/usr/bin/bdf -l |awk '$0 !~ /^F/' |awk '{print $5"\t" $6}'| sed 's/'%'/''/' >/tm
p/bdflist
}

panic ()
{
while read percent dir
do
if [[ $percent -ge 80 ]]
then
echo "File syste Full - `hostname`:$dir is at $percent%"
fi
done < /tmp/bdflist
}

output
panic

regards,
John K.

The latest version of Bill Hassell's bdfmegs shell script includes a '-P ' option to suppress output for filesystems with utilization <= pct. You can grab it from this thread:

One of the problems with bdf is that it automatically wraps a line if the source disk name is too long and this messes up all the numbers. My bdfmegs script can be run with any headers and show just the problem mountpoints. You can select the maximum percentage:

bdfmegs -qP 90

Only the mountpoints that are greater than or equal to 90% full will be shown.

Bill Hassell — Fri, 16 Nov 2007 12:26:23 GMT

Clarification: bdfmegs always shows each mountpoint on a single line making it ideal for scripting. I have attached the script here.

I hve used Bill'd bdfmegs quite successfully.
Here is one we have in production on all machines. It runs on Monday and Friday and looks for 80+% full as well as chack one particular vg.

Here's a wrapper script I've written around Bill's bdfmegs.sh:

#!/usr/bin/sh

typeset -i MAXPCT=95
typeset -i TIMEOUT=1 # number of days to retain LOCKFILE
BDFMEGS=/root/scripts/util/bdfmegs.sh
TEMPFILE=/tmp/check_filesystem_usage.${$}.tmp
LOCKFILE=/tmp/check_filesystem_usage.lck

# rm LOCKFILE if mtime > ${TIMEOUT}, so that duplicate reports will be generated, on occasion
find ${LOCKFILE} -type f -mtime +${TIMEOUT} -print | xargs rm -f 2> /dev/null
[ ! -f ${LOCKFILE} ] && touch ${LOCKFILE}

trap "[ -f ${TEMPFILE} ] && rm -f ${TEMPFILE}" 0 1 2 3 15
${BDFMEGS} -qglP ${MAXPCT} | grep -v '^$' > ${TEMPFILE}

if [ -s ${TEMPFILE} ]
then
$(grep -q -v -f ${LOCKFILE} ${TEMPFILE}) && \
{ grep -v -f ${LOCKFILE} ${TEMPFILE} >> ${LOCKFILE}
mailx -m -s "WARNING! FILESYSTEM(S) OVER ${MAXPCT}% FULL!" root << EOF
File-System Gbytes Used Avail %Used Mounted on
$(cat ${TEMPFILE})

Remember to delete ${LOCKFILE} after freeing up space!
EOF
}
# exit with rc of 1 if any filesystems with utilization > ${MAXPCT} were returned
exit 1
fi

# otherwise, exit with rc of 0
exit 0
