i followed this guide
http://www.reddit.com/r/litecoinmining/comments/1c4n7i/guide_getting_started_with_n_x_radeon_7950_on/here is my mine.sh
#!/bin/sh
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
cd /home/miner2/cgminer-2.11.3-x86_64
./cgminer --scrypt -o stratum+tcp://mine-EMD.scryptmining.com:3889 -u darer234..2 -p x -g 1 -w 256 --thread-concurrency 21712 -I 18 --lookup-gap 2

./cgminer: 1: ./cgminer: : not found
