$

But i can execute same script in different solaris server.Please let us know how to resolve this isse.
Code:
$ ./mem1.sh

$


Please find the below for script.
Code:
$ more mem1.sh
#! /bin/sh
if
MEMORY=`/usr/sbin/prtdiag -v |grep -i "Memory size"|awk '{if($NF ~ /Megabytes/) print  $3}'`;then
  REALMEM_GB=`echo "$MEMORY / 1024"|bc -l`
  SWAPMEM_USE=`sar -r 1 30 |grep Average|awk '{print $2}'`
  Swapmem_GB=`echo "$SWAPMEM_USE * 8 / 1024 /1024"|bc -l`
  TOTAL_UTILIZED=`echo "$REALMEM_GB - $Swapmem_GB"|bc -l`
  TOTAL_REAL_UTILIZED=`echo "$TOTAL_UTILIZED / $REALMEM_GB * 100" |bc -l`
  echo $TOTAL_REAL_UTILIZED
else
  MEMORY_GB=`/usr/sbin/prtdiag -v |grep -i "Memory size"|awk '{if ($NF ~ /GB/) print $3}'|sed "s/[^0-9]//g"`
  TOTAL_UTILIZED=`echo "$MEMORY_GB - $Swapmem_GB"|bc -l`

The syntax error is in relation with bc -l ...
If you had searched a bit in this forum, you would have found e.g.

In the else clause $Swapmem_GB never has a value. There appears to be 3 lines missing after the else.

MEMORY=`/usr/sbin/prtdiag -v |grep -i "Memory size"|awk '{if($NF ~ /Megabytes/) print  $3}'`;then
REALMEM_GB=`echo "$MEMORY / 1024"|bc -l`
SWAPMEM_USE=`sar -r 1 30 |grep Average|awk '{print $2}'`
Swapmem_GB=`echo "$SWAPMEM_USE * 8 / 1024 /1024"|bc -l`
TOTAL_UTILIZED=`echo "$REALMEM_GB - $Swapmem_GB"|bc -l`
TOTAL_REAL_UTILIZED=`echo "$TOTAL_UTILIZED / $REALMEM_GB * 100" |bc -l`
echo $TOTAL_REAL_UTILIZED
else
MEMORY_GB=`/usr/sbin/prtdiag -v |grep -i "Memory size"|awk '{if ($NF ~ /GB/) print $3}'|sed "s/[^0-9]//g"`
SWAPMEM_USE=`sar -r 1 30 |grep Average|awk '{print $2}'`
Swapmem_GB=`echo "$SWAPMEM_USE * 8 / 1024 /1024"|bc -l`
TOTAL_UTILIZED=`echo "$MEMORY_GB - $Swapmem_GB"|bc -l`
TOTAL_REAL_UTILIZED=`echo + "$TOTAL_UTILIZED / $MEMORY_GB * 100" |bc -l`
echo $TOTAL_REAL_UTILIZED
