Suppress a "No such file” message when using the ls command

[Richard Taubo]

Hi!

Trying to get the last pdf file in a directory and suppress a “No such file” 
message when a pdf file does not exist.
This works in zsh:
my_last_file=$(/bin/ls -t *.pdf  | head -1) 2> /dev/null

The same command returns a “No such file or directory” in bash when now pdf 
files are found.

I get this to work though, but that will require more steps:
my_last_file=$(/bin/ls -t *.pdf  2> /dev/null)

Thansk for any input!


Best regards
