Running multiple if statements

Hi,

Hav automated a process, and it is working fine.

for first process alone

Code:
status = ` ps -ef |grep a `
if [ $status -eq 1]
then
  echo " Success" > temp/logfile
else
  echo " Failure" > temp/logfile
fi


Now I hav to write script to automated some 2 process and then send mail using cron..

Code:
status = ` ps -ef |grep a `
if [ $status -eq 1]
then
  echo " Success" > temp/logfile
else
  echo " Failure" > temp/logfile
fi
status1 = ` ps -ef |grep b `
if [ $status1 -eq 1]
then
  echo " Success" > temp/logfile
else
  echo " Failure" > temp/logfile
fi

This script works when it is for one process, but when I run for two process, it is not workin, I recieve the result of the first process alone.

Pls, can u help me on this..


Thanks in Advance

Modify the redirection for the second test
Code:
status=` ps -ef |grep a `
if [ $status -eq 1 ]
then
echo " Success" > temp/logfile
else
echo " Failure" > temp/logfile
fi
status1=` ps -ef |grep b `
if [ $status1 -eq 1 ]
then
echo " Success" >> temp/logfile
else
echo " Failure" >> temp/logfile
fi

You can also write :
Code:
{ ps -ef |grep a && echo Failure || echo Success ;} >  temp/logfile
{ ps -ef |grep b && echo Failure || echo Success ;} >> temp/logfile

Add 'set +x' at the begining of the script and show us the output.
Code:
set -x
status=` ps -ef |grep a `
if [ $status -eq 1 ]
then
echo " Success" > temp/logfile
else
echo " Failure" > temp/logfile
fi
status1=` ps -ef |grep b `
if [ $status1 -eq 1 ]
then
echo " Success" >> temp/logfile
else
echo " Failure" >> temp/logfile
fi

Hi.

What exactly are you hoping to achieve here? status and status1 will contain a string of process information, not a number.

If you want the count of processes then you should look at piping the output of ps | grep through wc (or using grep -c). The aigles alternative is nicer in any case Smilie
