[Solved] Error in script while counting processes

Hi all,

Below is a script I'm writing and giving me error:

Code:
#!/usr/bin/sh
if [ ps -ef|grep dw.sap|wc -l -gt 17 ]; then
       echo "Success!"
else
       echo "Failure!"
fi

Normally if I do
Code:
ps -ef|grep dw.sap|wc -l

it gives me output of 18. So my script checks if it's greater than 17 it echoes success else failure

Please suggest how to correct this.

regards.

Hello,

Could you please try the following and let us know.

Code:
if [[ `ps -ef|grep dw.sap|wc -l` -gt 17 ]]; then
        echo "Success!"
else
        echo "Failure!"
fi


Thanks,
R. Singh

Code:
#!/usr/bin/sh
if [ $(ps -ef|grep dw.sap|wc -l) -gt 17 ]; then
       echo "Success!"
else
       echo "Failure!"
fi

Use -c with grepinstead of wc -l
Code:
#!/usr/bin/sh
if [ $( ps -ef | grep -c dw.sap ) -gt 17 ]; then
       echo "Success!"
else
       echo "Failure!"
fi

The following are more precise perhaps (you didn't provide a ps output)
Code:
$( ps -ef | grep -c 'dw[.]sap' )

Code:
$( ps -ef | grep -wc 'dw[.]sap' )
