if test for higher value between 2 decimal numbers
Hi
I would like to test for a max number value. It may be a decimal so I know I have to pipe into bc.
I just cannot get the syntax for this to work. I cannot get passed an error with the bracket - see below.
Any help appreciated.
Regards
Ewan




This works:

Code:
[ewan@sbc-san-01]/export/home/ewan> cat xx.ksh
#!/bin/sh
uname -a

max=6
val=3
if [ $max -gt $val ]
  then
    echo MAX $max VAL $val
  fi

Output:
=======
Code:
[ewan@sbc-san-01]/export/home/ewan> ./xx.ksh   
SunOS sbc-san-01 5.10 Generic_144488-12 sun4v sparc SUNW,SPARC-Enterprise-T5220
MAX 6 VAL 3





This fails:

Code:
[ewan@sbc-san-01]/export/home/ewan> cat ./xx.ksh
#!/bin/sh
uname -a

max=6
val=3
#if [ $max -gt $val ]
if [ $(echo "$max -gt $val" |bc) -eq 1 ]
  then
    echo MAX $max VAL $val
  fi

Output:
=======
Code:
[ewan@sbc-san-01]/export/home/ewan> ./xx.ksh    
SunOS sbc-san-01 5.10 Generic_144488-12 sun4v sparc SUNW,SPARC-Enterprise-T5220
./xx.ksh: syntax error at line 7: `(' unexpected
