BASH SCRYPT for ALGO SWITCHING--
This is a rough edit from Skunk's earlier posting. 3 big differences:
1) NiceHash has changed the ID number for some algos, and eliminated x14 and fresh algos.
2) TradeMyBit (TMB) is gone.
3) ALL algos can be mined with just CCminer now. No need for CudaMiner or NeoGpuMiner.
This script is set up to mine at NiceHash and Yaamp. I was getting syntax errors. I execute the script as "sudo ./switch.sh", it runs, it mines, it doesn't switch just ok yet. I hope some other user(s) might want to work the bugs out.
Right now, the script launches cleanly, and reports the best paying algo between NiceHash and Yaamp every minute, and mines! My error was using an abreviation for my home directory. I just corrected it; use the full path from root to your mining directory with "ccminer". I am still looking for bugs...
For what it is worth:
