[转]caffe学习 训练日志输出

eg：./build/tools/caffe train --solver=models/bvlc_reference_caffenet/solver.prototxt 2>&1| tee yourpath/caffe.log

1. tee的意思就是命令行信息重定向的命令

2. 2>&1的意思是错误的信息也当成标准信息输出，这样能够保证输出log信息的完整性。

File descriptor 1 is the standard output (stdout).
File descriptor 2 is the standard error (stderr).

Here is one way to remember this construct (although it is not entirely accurate): at first, 2>1 may look like a good way to redirect stderr to stdout. However, it will actually be interpreted as "redirect stderr to a file named 1". & indicates that what follows is a file descriptor and not a filename. So the construct becomes: 2>&1.
