Unary Operator Message - Linux/Unix
I have this code to check the largest files by bytes. Whenever I run it, I keep getting an error message "unary operator expected"

Code:
for i in *
do
if
set -- $(ls -ls "$i")

alias filesize='ls -lS'

[ "$i" -gt $filesize ]
then
echo $1: $5 bytes
fi
done

This script has serious issues. If you are looking for files > 20000 bytes (an example)
do this:

Code:
lim=20000
ls -ls | sort -rn | 
  awk -v lim=$lim ' $6>= lim { print $ 0; next}  {exit} '  > /path/to/outputfile

This puts the files in order from big -> small, and reads until the filesize $6 is less than the variable lim.
