Shell Programming and Scripting

i need to write a shell script for printing the list of filesystems whose disk utilization is more than 75%...i tried using df -h along with awk but cud'nt make the combination work.....
when we do df -h then the filesystems which are using more than 75% capacity shud be printed according to the requirement......please help me with it...thanks..
m working on ksh!!

Try:

Code:

df -hP | awk '{x=$5;sub ("%","",x)}x>75'

It looks work too with:

Code:

df -h | awk '$5>75'

or similar to bartus solution:

Code:

df -h | awk '{sub(/%/,"")}$5>75'

Hope it helps

Regards

Thanks bartus11, i was unaware of the option -P hence came up with below..

Code:

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

@bartus...it showing the following error
tc95air1(root)# ./script2
df: unknown option: P
Usage: df [-F FSType] [-abeghklntVvZ] [-o FSType-specific_options] [directory | block_device | resource]
awk: syntax error near line 1
awk: illegal statement near line 1


@michael: it's executing and givin the output but the o/p seems to be wrong
tc95air1(root)# ./script1
Filesystem size used avail capacity Mounted on
/dev/dsk/c1t0d0s6 9.8G 724M 9.0G 8% /unused2

but when i run df -h the following records are shown
tc95air1(root)# df -h

the output doesn't match with the records as it's showing a file system with "8%" usage which is less than 75%.....please help me with this..

Could you try the below..

Code:

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

Which Solaris version are you using?
