watch out for spaces around [ and ]
Code:
if [ `grep "$abcd" file1` -gt 0 ]

And...remove the spaces around the equal sign:

Code:
abcd="Hello world"

Maybe your shell don't like the syntax, try this:

Code:
#!/bin/sh
abcd="Hello world"

grep "$abcd" file > /dev/null

if [ $? -eq 0 ]
then
   echo "$abcd"
fi
