I have been trying to:



cp file.csv file.$(date +%D).csv


But it fails because the filenames is: file.03/27/19.csv with the slash of separate directories.



And I have been trying again to:



cp file.csv file.$(printf "%q" $(date +%D)).csv


But it still fails.

  • the problem is your use of the date format using the / character. You said it yourself, the shell is seeing them as directory markers. Try one of the many other options available from date. You might be able to get the / escaped so the filename uses the character code (like putting a space in a filename), but that is often problematic.

You can't have / (byte 0x2F on ASCII-based systems) in a file name, period.



You can use characters that look like / like ⁄ (fraction slash), so you could do:



 cp file.csv "file.$(date +%D | sed 's|/|⁄|g').csv"


But you may run into problems like the file name being rendered differently in locales using a different charset.



My advice would be to use the standard non-ambiguous (for most people outside the US, 03/12/18 would be interpreted as the 3rd of December 2018 for instance) YYYY-mm-dd format instead (which also helps wrt sorting):



 cp file.csv "file.$(date +%Y-%m-%d).csv"


Which with many date implementations you can shorten to:



 cp file.csv "file.$(date +%F).csv"
