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.....:wall:
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:
df -hP | awk '{x=$5;sub ("%","",x)}x>75'
It looks work too with:
df -h | awk '$5>75'
or similar to bartus solution:
df -h | awk '{sub(/%/,"")}$5>75'
Hope it helps
Regards
Thanks bartus11, i was unaware of the option -P hence came up with below..
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

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

@michael: it's not giving any output now, initially i thot tha no file system must be using more than 75% tht's y, later i changed the threshold to 60%, then too no results...
tc95air1(root)# ./script1
tc95air1(root)#
On Solaris df works different when the output is a terminal or a non-terminal

To a terminal, df split long lines into two lines. But when piped to cat, it allowed long lines to stay intact. So we don't need to worry about split lines inside the awk program. Also, on Solaris awk is an antique version. Use nawk to get a "modern" (well, circa 1985) version of awk.
Try this one:
$ cat /etc/release

Thanx Perderabo....it's workin perfect...
Hey Perderabo,
Can u please add a couple of functionalities to ur command...a mail containing the file system name and usage % should be fired to an ID whenever any file system crosses the threshold set by us..i.e 75%..
what about for HPUX..using bdf
