Question Monitor capacity of directory
Good morning.

I have been attempting to find a way to monitor the capacity of a directory so that when it reaches 80% or higher I can send an event.

I was able to find a script that does this for the whole drive by I can not seem to figure out how to do this for just a single directory.

Code:
ADMIN="myemail@someplacecool.com"
# set alert level 90% is default
ALERT=60
df -hl | egrep -ve '/lcl/prd/apps/Tivoli/playground' | awk '{ print $5 " " $1 }' | while read output;
do
  echo $output
  usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  )
  partition=$(echo $output | awk '{ print $2 }' )
  if [ $usep -ge $ALERT ]; then
    echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)" |
     mail -s "Alert: Almost out of disk space $usep" $ADMIN
  fi
done

As you can see from above I am attempting to get the capacity of /lcl/prd/apps/Tivoli/playground and if its 90% or over then it sends an e-mail.

However when I try this is the results...
Code:
"test.sh" 14 lines, 586 characters
seville:/lcl/prd/apps/Tivoli/playground>./test.sh
capacity Filesystem
./test.sh: line 10: [: capacity: integer expression expected
81% /dev/md/dsk/d10
0% /devices
0% ctfs
0% proc
0% mnttab
1% swap
0% objfs
0% sharefs
0% fd
1% swap
1% swap
67% /dev/md/dsk/d100

I am not very good yet with shell scripting so I am kinda stuck here.
Any help would be great.

Thank you.

-----Post Update-----

Figured it out.

Code:
#!/bin/ksh
space=`df -bhk /lcl/prd/apps/Tivoli/playground | cut -d "c" -f1 | awk '{print$5}'`
capacity=${space%?}
echo $capacity
if [ $capacity -gt 70 ]; then
echo "Getting full! $capacity"
else
echo "Below percent trap."
fi

Code:
alert=80
partition=/lcl/prd/apps/Tivoli/playground

df -hl "$partition" | {
 read ## discard header
 read fs size used available percent mount
 if [ ${percent%?} -gt $alert ]
 then
   host=$(hostname)
   date=$(date)
   fmt='Running out of space "%s (%s)" on %s as on %s\n'
   printf "$fmt" "$partition" "$percent" "$host" "$date" |
     mail -s "Alert: Almost out of disk space $usep" $ADMIN
 fi
}
