You seem to be mixing up old and modern bash or ksh93 scripting integer syntax. I suggest you stick to modern syntax. Also make sure that you have a appropriate shebang as the first line of your script.
Code:
$ a=0
$ b=40000
$ c=10000
$ a=$(( b - c ))
$ echo $a
30000
$ d=$(( a - 10000 ))
$ echo $d
20000
$ d=$(( a - 50000 ))
$ echo $d
-20000
$ if (( d > 0 ))
> then
> echo "greater"
> fi
$

5 SIZE_SCR=`grep ^scr /rsi/logs/csc_summary_size_check.log | tail -1 | cut -d";" -f4 | cut -b1-4`
6 b=$SIZE_RSI
7 y=$SIZE_SCR
8 echo "$b"
9 echo "$y"

13 c=$SIZE_VORHER_RSI
14 z=$SIZE_VORHER_SCR
15 echo "$c"
16 echo "$z"
17
18 let a=0
19 a=$(( b - c ))
20 echo "$a"
21 d=$(( a - 1000 ))
22 echo "$d"
23 if [ "$d" -gt "0" ] ; then
24 sendme /rsi/logs/csc_summary_size_check.log stefan
25 fi
26
27 let x=0
28 a=$(( y - z ))
29 echo "$x"
30 w=$(( x - 1000 ))
31 echo "$w"
32 if [ "$w" -gt "0" ] ; then
33 sendme /rsi/logs/csc_summary_size_check.log stefan
34 fi

and the messages after starting are:
sum result is:
3927 is OK
1479 is OK
3927 is OK
3927 don't know why this is shown here
1471 is OK
1479 don't know why this is shown here

Out of some reason he do not know the numbers as what they are. This is confusing. And to all who help me a gret thank you.

Thanks. (3 Replies)
