File size check

Shell Programming and Scripting
1

I am trying to check whether two files are empty or not using below if condition but its checking for only one file

if [[ -s file1.csv && -s file2.csv ]]

Again I tried

if [[ -s file1.csv ] && [-s file2.csv ]]

Need your assistance

Almost:

if [ -s file1.csv ] && [ -s file2.csv ]
then    echo 'both file1.csv and file2.csv have a size greater than 0'
fi

This syntax also works, at least in bash.

if [ -s file1.csv -a -s file2.csv ]
