parse_log.sh script failing on Mac OS X

[onkarganjewar]

Issue summary

I'm trying to run the caffe/tools/extra/parse_log.sh script on my mac, but getting this error:

$ ./tools/extra/parse_log.sh sample-log.log 
sed: 1: "aux.txt": command a expects \ followed by text

Debug logs:

+ sed -n '/Iteration .* Testing net/,/Iteration *. loss/p' sample-log.log
+ sed -i '/Waiting for data/d' aux.txt
sed: 1: "aux.txt": command a expects \ followed by text

Am I using this script correctly? If so, are there any guidelines provided regarding this particular issue anywhere? I believe this error is due to the -i flag of sed, which apparently requires an extension of backup to be provided when running on OS X, if I'm not mistaken.

Steps to reproduce

Run this on Mac OS X:

$ ./tools/extra/parse_log.sh <your_caffe_log_file.log>

Tried solutions

I tried adding the extension .bak to wherever sed -i is being used, like this:

sed -i .bak '/Waiting for data/d' aux.txt
sed -i .bak '/prefetch queue empty/d' aux.txt
sed -i .bak '/Iteration .* loss/d' aux.txt
sed -i .bak '/Iteration .* lr/d' aux.txt
sed -i .bak '/Train net/d' aux.txt

This appears to have worked in my local machine, but not sure if it is the right way to do it. If it is, I would be happy to make a PR. :)
