Getting error in SAS MID Tier Services script

Question:
We are getting below error while executing the SAS Mid tier services script while starting.

Starting SAS Web App Server: SASServer11_1
(this can take a while)
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 60 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected

We open the script using VIM editor and checked in the line 192 ,there is only a if then statement which an we believe it is a valid one.   

ROLLCHK=`ls -l $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`
# clear leading blanks, then strip trailing filename
ROLLCHK=`echo $ROLLCHK | tr -s ' ' | cut -d ' ' -f 5`
if [ $ROLLCHK -lt $ROLLMARK ];
then
{
echo "Note: $SASWEBAPPINSTANCE server.log rolled over during startup."
MYMARK=1
}
fi

Though the services status is showing as UP but we are not able to open any Mid Tier application.

Answer:

Modify lines 152 and 188 of sas.servers.mid to use "ls -n" instead of "ls -l" when querying the server.log file to get around this problem:

 

From

ROLLMARK=`ls -l $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`

ROLLCHK=`ls -l $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`

To

ROLLMARK=`ls -n $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`

ROLLCHK=`ls -n $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`

It looks like either user or group names contain spaces.
