In freeswitch as I am setting the variable like this

<action application="set" data="RESULT=${system sed -n 1p /nfs/th/play/${uuid}}" inline="true"/>

 Here i am trying to assign the wav file path to the variable,but here the problem is it is getting assigned as

2014-05-08 13:34:56.659049 [DEBUG] mod_dptools.c:1402 sofia/internal/1002@192.168.0.106 SET [RESULT]=[/usr/local/freeswitch/sounds/en/us/callie/directory/8000/dir-for_prev.wav

]

The variable RESULT is not being set properly,The closing square bracket is coming to the new line as it should be in the same line immediately after the path.So while playing the wav file it is showing the error as

2014-05-08 13:34:56.679046 [ERR] switch_core_file.c:150 Invalid file format [wav

] for [/usr/local/freeswitch/sounds/en/us/callie/directory/8000/dir-for_prev.wav

]!

Can anyone help me in solving this issue.Thanks in advance
