一、SSH over http

Corkscrew是专门为ssh提供http代理的软件，要使用corkscrew需要http代理支持HTTP CONNECT方法，建议使用squid或者ATS这类专业的代理软件，代理不建议设置认证

1.1 Corkscrew安装

下载：

wget http://agroman.net/corkscrew/corkscrew-2.0.tar.gz 编译安装：

JQ to filter JSON by value

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

# 1. extract audio from all videos (assuming .mp4 videos).
for FILE in *.mp4; do ffmpeg -i $FILE ${FILE%%.mp4}.wav; done

# 2. use the first second of the first audio file as the noise sample.
sox `ls *.wav | head -1` -n trim 0 1 noiseprof noise.prof

# Replace with a specific noise sample file if the first second doesn't work for you:
# sox noise.wav -n noiseprof noise.prof

# 3. clean the audio with noise reduction and normalise filters.
