I saw the following script in an earier post in this forum. Changed a little bit and trying it in my env but getting errors. Pls help in debuggin this.

(1)
#!/bin/ksh

DFR='df -g filesystempath|grep filesystem|awk '{print $4}''

echo $DFR
-----------------------
scriptname[3]: }: not found.

(2)
#!/bin/ksh

DFR='df -g filesystempath|grep filesystem|awk '{print $4}''

if [ DFR[2]>=90 ] then echo "True" else echo "False" fi
#checking if its greater than 90%

------------------------------
script:}: not found.
script: 0403-057 Syntax error at line 5 : `if' is not matched.

Thanks

(1) needs backticks --- character under ~ (tilde) on your keyboard ...

#!/bin/ksh

DFR=`df -g filesystempath|grep filesystem|awk '{print $4}'`

echo $DFR

(2) needs to be properly formatted ... and use backticks ... and use right test syntax ...

#!/bin/ksh

DFR=`df -g filesystempath|grep filesystem|awk '{print $4}'`

if [ $DFR -gt 90 ] 
then 
    echo "True" 
else 
    echo "False" 
fi 
#checking if its greater than 90%

Thanks

It was the backticks

Proper Script:
#!/bin/ksh //correct

DFR=`df -g /dev/devetl_lv|grep devetl_lv|awk '{print $4}'|sed 's/\%//'`
//correct

if [ $DFR -gt 90 ] then echo "True" else echo "False" fi
//wrong.....it says 0403-057 Syntax error at line 6 : `then' is not matched.

Please let me know whats wrong. I did try with ';' after the expression [..], but didnt help

if [ $DFR -gt 90 ] ; then echo "True" ; else echo "False" ; fi
