for loop in awk?

I am new to unix and have pieced together two scripts that work independently.


The first checks all the filesystems and reports which are running low on space.
Code:
df -m | awk 'int($4) > 75 {



print $1 " has only " $3 "mb free from a total of " $2 ", this filesystem is
" $4 " full! \n"
} '

The second script prints all directories on a given filesystem and shows how much space it takes up. Shown below is printing the directories at root

Code:
for loop in $(ls -l / |grep ^d |awk '{print $9}')
do
printf "Directory : %-15s | Filesystem : %-15s | Size (MB) : %-10s \n" $loop,
 $(df /$loop| tail -1 |awk '{print $7}'), $(du -sm /$loop| awk '{print
$1}')
done

Both of these are working as i want them to, but my problem is that i want them to work together. I want to run the first script to see which filesystems are running low on space. If any are indeed running low, i want it to then use the second script on the directory that the filesystem is mounted on.


What i did was the following.

Code:
!/bin/ksh

df -m | awk 'int($4) > 75 {



print $1 " has only " $3 "mb free from a total of " $2 ", this filesystem is
" $4 " full! \n"




for loop in $(ls -l $7 |grep ^d |awk '{print $9}')
do
printf "Directory : %-15s | Filesystem : %-15s | Size (MB) : %-10s \n" $loop,
 $(df /$7/$loop| tail -1 |awk '{print $7}'), $(du -sm /$7/$loop| awk '{print
$1}')
done
} '


So now the for loop is inside the first awk, so it can call upon $7 which is the directory the filesystem is mounted on. However when running this script i recieve an arror at the for loop.

>>>>>>loop<<<<<

Is there any reason i cannot run this for loop inside of awk? What other methods could i pursue to display this information? Sorry in advance for any nomenclature mistakes i have made, im still new!
