Error message

Shell Programming and Scripting
1

I am new to scripting.
I am using the following script . BART.dat contains the string 'Y' .

#!/bin/ksh
cd /work/TCI/data_out

file=`cat BART.dat`
echo "$file"
if ["$file"=="Y"]; then
echo "true"
fi

When i am executing the above script i am getting the following error
./s.ksh[6]: [Y==Y]: not found

What could be the problem.

Thanks in advance

i dont know but this line should be checked
replace

if ["$file"=="Y"];

by

if [ "$file" = "Y" ];

Please note space after [ and before ] and =

The operator for equality test is = not ==
With ksh you can read a file into a variable with the $(<file) syntax

#!/bin/ksh
cd /work/TCI/data_out

file=$(<BART.dat)
echo "$file"
if [ "$file" = "Y" ]; then 
   echo "true"
fi
