.sh file to check if file exists with dynamic name

Question

I created a sample .sh file with script like this:

if [ -f "/Spool/Cognos/Cognos.xlsx" ]
then 
    echo "File exists"

else
  echo "File not exists"
fi

However, I would like to change so that it could read file with dynamic names, the files that will be uploaded in the folder /Spool/Cognos will be something like this: Cognos Aug24.xlsx, Cognos Sep24.xlsx, Cognos July24.xlsx, etc.

How can I change the if part of the script above? I tried if [ -f "/Spool/Cognos/Cognos*.xlsx" ] with * as wildcard but it seems like it does not work.

You can do it like this:

for f in /Spool/Cognos/Cognos*.xlsx; do
  if [ -f "$f" ]; then
    echo File exists
  else
    echo File not exists
  fi
  break
done

If you don't mind overwriting the positional parameters, this will also work:

set -- /Spool/Cognos/Cognos*.xlsx
if [ -f "$1" ]; then
  echo File exists
else
  echo File not exists
fi
