you can use

Code:
 
wc -l < filename

it will show the output as 2 ( if you have a newline )

@ygemici: why all that bash/ksh juggling Smilie, when this part:
Code:
echo "$(<file)"

would suffice? or (POSIX)
Code:
printf "%s\n" "$(cat file)"

yes you're right Smilie , actually just printf was enough instead of if loop Smilie
Code:
printf "%s\n" "$(cat file)"
