alias in CSH
Hello guys,

I want to use an alias as an sub function in the script. Here is my issue:
I want to use
Code:
exsit_en <pattern> <file>

to indicate that if the <file> contains <pattern> the expression returns 1, and vice versa.
But in the alias I used as follows, the $status alway is 0. Can someone provide a solution about this?

Code:
alias exsit_en 'eval " grep -i \!:1 \!:2 >& /dev/null \\
                        if ( $status == 0 ) then \\
                                echo 1  \\
                        else    \\
                                echo 0  \\
                        endif " '
