Shell Programming and Scripting

hi all,

for an example :
df -k output shows:

$ df -k

/dev/cciss/c0d0p6 3099260 1117760 1824068 8% /

tmpfs 524288 523765 523 94% /tmp

I want to search for above 80% usage...
for the above example /tmp and /opt Filesystem are exceeding

i need to add a word "HI" before starting of the line and "BYE" after the line
in our case:
HI tmpfs 524288 523765 523 94% /tmp BYE

I'm new to sed scripting, anybody help is greatly appreciated

Try...

Code:

awk '{s=substr($5,1,match($5,"%")-1)
if (s > 80)
   $0="Hi "$0" Bye"
   print
   }' inputfile

Hi All

I want to show df -h, whichever F/S is 80% above i need to add "HI" at Starting of the Line and "BYE" at the ending of the line.

Example shown as below:

[itgcead7@lrtp68 cgi-bin]$ df -h

/dev/cciss/c0d0p6 3.0G 1.1G 1.8G 37% /

/dev/cciss/c0d0p2 17G 76M 16G 1% /var/diskdump
HI tmpfs 512M 412M 101M 81% /tmp BYE

Try this,

df -k | awk '$5 >= "70%" { printf "HI "; printf; printf " BYE"; printf "\n"; }'

I don't think you can compare it with %...

I have checked in my server and its works fine!!

Hi,

Try this.

894t005 $df -h |awk '$5>80{print "HI " $0 " BYE"}'|grep -v "Filesystem"HI /lib 9.8G 8.6G 1.1G 89% /lib BYE
