Script to rename a file

Hello All,

I have some problems to write a script to rename a file on a network path.

My script is :

print(exec('cmd', 'rename \\\sapbodsdev2\\input\\test_CRM\\VH_003368_20141101_MI023368.CSV BCK.csv'));

Am getting the error :

Function call <exec ( cmd, rename \\sapbodsdev2\input\test_CRM\VH_003368_20141101_MI023368.CSV BCK.csv, 0 ) > failed, due to

error <50306>: <Function <exec> failed to execute program <cmd rename \\sapbodsdev2\input\test_CRM\VH_003368_20141101_MI023368.CSV BCK.csv>. Program terminated with exit code <1>.>.

Do you have any idea?
