I am trying to check for the existence of a file using the 'test' and the file existence options.
When trying to check for a file with a space in between e.g 'Team List', it gives the following error.
learn1: line 3: test: `Team: binary operator expected
I am pasting my code below as well:
echo "Please enter a file name"
read fname
if test -f $fname
then
echo "$fname exists"
else
echo "$fname doesnot exist"
fi
Space is one of the default input field seperators.
So, if you just use $fname then that's 2 arguments for test and hence doesn't work.
"$fname" is just 1 argument.
If you consider that the test command is looking for a single argument, and then you provide it with a list, then it will only test the first item in that list.
So, I created a test script named "test.ksh". Here it is:
I also created a file in the same directory named "one two.txt".
Then I changed test.ksh to remove the double quotes around the variable "filename":
I ran this in an identical manner as before:
I believe that this is due to the way that the test function works. When presented with a list of words separated by spaces, it tests the first item in that list (in this case, part of a filename), but if that list of words is surrounded by double quotes, then it is viewed as a single argument, and the test is then successful.
