Having trouble executing an IF statement through tcsh. This works FINE for me -

#!/bin/bash
if echo `cal|tail -6|sed -e 's/^.\{3\}//' -e 's/.\{3\}$//' |tr -s '[:blank:]' '\n' | head -11|tail -10|tr -s '\n' ' '`|grep -w `date "+%e"`
then
        echo "present"
else
        echo "absent"
fi

This is the PROBLEM -

#!/bin/tcsh
if echo `cal|tail -6|sed -e 's/^.\{3\}//' -e 's/.\{3\}$//' |tr -s '[:blank:]' '\n' | head -11|tail -10|tr -s '\n' ' '`|grep -w `date "+%e"`
then
        echo "present"
else
        echo "absent"
endif

Getting this error-

if: Expression Syntax.
then: Command not found.

I really need this to run using "tcsh"
