I want to compare two files and see if they are the same or not in my shell script, my way is:
diff_output=`diff ${dest_file} ${source_file}`
if [ some_other_condition -o ${diff_output} -o some_other_condition2 ]
then
....
fi
Basically, if they are the same ${diff_output} should contain nothing and the above test would evaluate to true.
But when I run my script, it says
[: too many arguments
On the if [....] line.
Any ideas?
