记不住参数，每次都要插度娘，太麻烦了，所以我把唯一的常用功能固化成一个脚本…
#!/bin/bash if [ "x${3}" == "x" ]; then echo "Usage: ${0} inFile.name \$startTime[hh:mm:ss] \$endTime[hh:mm:ss] [outFile.name]"; exit 1;
fi
#ifName="${1%.*}"
ifName=$(basename "${1}")
ifName="${ifName%.*}" ifExt="${1##*.}"
if [ "x${4}" == "x" ]; then
ofix=$(echo "${2}-${3}"|tr -d ': ') oFile="${ifName}.${ofix}.${ifExt}"; else
oFile="${4}"; fi ffmpeg -i "${1}" -vn -acodec copy -ss ${2} -to "${3}" "${oFile}"
