How to accept multiple input into a same script

How can I accept multiple-line input into a same script. Or in other words to process multiple files with the following script:

#!/bin/bash
echo 'Enter file names (wild cards OK)'
read input_source
if test -f "$input_source"
then 
sort $var | uniq -c | head -10
fi

Just cat all the files that match the input pattern-:

#!/bin/bash
echo 'Enter file names (wild cards OK)'
read input_source
cat $input_source | sort | uniq -c | head -10

Add a for loop:

#!/bin/bash
echo 'Enter file names (wild cards OK)'
read files
for input_source in $files ; do
    if test -f "$input_source" ; then 
        sort $var | uniq -c | head -10  # You probably should include $input_source somewhere
    fi
done

Use a while loop:

while read input_source 
do
# Do something with $input_source
done
