我的剧本是:
#!/bin/bash
LGREEN='\033[1;32m'
LBLUE='\033[1;36m'
NC='\033[0m'
function convertToTime {
min=$(echo "$min+$sec/60" | bc)
sec=$(echo "$sec%60" | bc)
hrs=$(echo "$hrs+$min/60" | bc)
min=$(echo "$min%60" | bc)
}
function convertToTimeTotal {
totalMin=$(echo "$totalMin+$totalSec/60" | bc)
totalSec=$(echo "$totalSec%60" | bc)
totalHrs=$(echo "$totalHrs+$totalMin/60" | bc)
totalMin=$(echo "$totalMin%60" | bc)
}
totalSec=0
totalMin=0
totalHrs=0
function recursiveDirFinder {
presentDir=$1
cd "$presentDir"
ls >filelist.tmp
sec=0
min=0
hrs=0
while
read fileName
do
if
test -d "$fileName"
then
presentDir+="/$fileName"
recursiveDirFinder "$presentDir"
presentDir=$1
else
if [[ $fileName == *.mp4 ]]; then
s=`ffprobe -v quiet -of csv=p=0 -show_entries format=duration "$fileName"`
sec=$(echo "$sec+$s" | bc)
fi
fi
done <filelist.tmp
convertToTime
echo -e "Video Duration in $1 is ${LBLUE}$hrs:$min:$sec${NC}"
totalSec=$(echo "$totalSec+$sec" | bc)
rm filelist.tmp
cd ..
}
recursiveDirFinder "E:/RBR Lectures"
convertToTimeTotal
echo -e "Total Duration is ${LGREEN}$totalHrs:$totalMin:$totalSec${NC}"
我最初是在Ubuntu 16.04.1 LTS x64上写的。然后我在Win8 x64上安装了cygwin并尝试运行该脚本。我得到了错误:
(standard_in)1:非法字符:^ M
(standard_in)1:语法错误
我搜索了一下,发现它主要是由DOS中的unix字符引起的,反之亦然。我在文件dos2unix
(我的脚本)上运行了durationAdder.sh
,输出建议成功转换。但我仍然不断收到错误。为什么会这样,我该如何解决?
答案 0 :(得分:1)
为了将来的参考,我会为可能遇到同样问题的其他可怜的灵魂发布我自己的答案。
问题是我预编译的ffprobe(因为cygwin无法编译它)以DOS格式输出。这个cygwin不喜欢,并且犯了一个错误。解决方案是将输出转储到文件ffpOut
中,使用dos2unix静默转换,然后将输入反馈到适当的变量中。
工作代码是:
LGREEN='\033[1;32m';
LBLUE='\033[1;36m';
NC='\033[0m';
function convertToTime {
min=$(echo "$min+$sec/60" | bc);
sec=$(echo "$sec%60" | bc);
hrs=$(echo "$hrs+$min/60" | bc);
min=$(echo "$min%60" | bc);
};
function convertToTimeTotal {
totalMin=$(echo "$totalMin+$totalSec/60" | bc);
totalSec=$(echo "$totalSec%60" | bc);
totalHrs=$(echo "$totalHrs+$totalMin/60" | bc);
totalMin=$(echo "$totalMin%60" | bc);
};
totalSec=0;
totalMin=0;
totalHrs=0;
function recursiveDirFinder {
presentDir=$1;
cd "$presentDir";
ls >filelist.tmp;
sec=0;
min=0;
hrs=0;
while
read fileName;
do
if
test -d "$fileName"
then presentDir+="/$fileName";
recursiveDirFinder "$presentDir";
presentDir=$1;
else
if [[ $fileName == *.mp4 || $fileName == *.MP4 ]];
then
`ffprobe -v quiet -of csv=p=0 -show_entries format=duration "$fileName">ffpOut`
dos2unix -q ffpOut
s=`cat ffpOut`
sec=$(echo "$sec+$s" | bc);
rm ffpOut
fi;
fi;
done <filelist.tmp;
convertToTime;
echo -e "Video Duration in $1 is ${LBLUE}$hrs:$min:$sec${NC}";
totalSec=$(echo "$totalSec+$sec" | bc);
rm filelist.tmp;
cd ..;
};
recursiveDirFinder "E:/RBR Lectures";
convertToTimeTotal;
echo -e "Total Duration is ${LGREEN}$totalHrs:$totalMin:$totalSec${NC}"
谢谢大家的时间和答案。
