Check if a file is already committed to svn

Question

How do I check if a file/folder is already committed to svn ? I have a shell script where I want to ensure that the file/folder selected by user for check-in isn't already committed. For eg if I try to check-in a folder that's already committed using

svn add myfolder

I get the following warning:

svn: warning: 'myfolder' is already under version control

Use the return code of svn info. It's 0 if under version control, non-zero otherwise.

My shell displays non-zero return codes after a command, so it looks like this:

$ svn info trunk
Path: trunk
URL: https://(...)/trunk
Repository Root: https://(...)
Repository UUID: 651713a4-5a46-7e42-a99e-f31e79777eab
Revision: 213
Node Kind: directory
(...)

$ touch foo
$ svn info foo 
foo:  (Not a versioned resource)

svn: A problem occurred; see other errors for details

rc: 1

How you'd do it in a bash script (similar in other shells), with suppressing info output:

svn info <filename> 1>/dev/null 2>&1
echo $?
