I want to check if file exists but only checking if some the filename exists

For example in some folder I have these files (Date format: AAAAMMDD):

Rejets\_20190112.csv.zip 

Rejets\_20190312.csv.zip 

Rejets\_20190314.csv.zip 

I want to check if there is a file that begins with Rejet\_DAP\_201903 exists in that folder. In other word I want to check if Rejet\_DAP file with current year and month exist, the day doesn't matter.

Here's what I tried to do in my script:

```
jour=`date +%d`
mois=`date +%m`
annee=`date +%Y`

    FILE="/appli/project/echanges/RTY/receptions/Rejet_${annee}${mois}"_*

    if [[ -e $FILE  ]]
    then
            echo "FILE EXISTS"
    else
            echo "FILE DOES NOT EXIST"

    fi

```
