I'm creating a simple .sh and trying to put a date(yyyymmdd) in the end of my filename

today=$(date +"%Y%m%d")
file="/nas/backup_$today.sql"
echo $file

But when I print the name, this is the result:

.sql/backup_02_10_2022

How can I keep the ".sql" in the end of the name?

    I'm not sure how this is what is being echoed. I tried on sh, bash, zsh, and ksh and they all print "/nas/backup_20220210.sql". – erip Feb 10 '22 at 21:11

    Your script has DOS line endings; `today` ends with a carriage return. `file` *does* end with `.sql` (well, `.sql\r`), but the carriage return moves the cursor while displaying the value. – chepner Feb 10 '22 at 21:11
