if and test not working
All,

I am getting error when run file check with test operator . Why is it showing the error

Code:
if [ test -r filename ]             
 then
 echo 'file found'
  fi

ksh: -r: unknown test operator


I know i can use the below code to test the file but why the above is not working

Code:
if test -r filename
 then
 echo 'filename found'
 fi

Thanks,
Arun

test and [ are the same command, you cannot use both at the same time.
Code:
if [ -r filename ]             
then
  echo 'file found'
fi
