Linux脚本，用于查找所有视频文件扩展名和文件大小

时间：2011-11-04 21:22:23

标签： linux bash scripting find

我试图编写几个可以执行以下操作的脚本：

  1. 递归列出给定目录中的所有文件类型并给我 该文件类型的文件总数和文件总大小 对于每个（即.doc = 300和450 MB，.xlsx = 543和516 MB，.mov = 67和5.4 GB等）

  2. 一个脚本，它会以递归方式查找我服务器上的所有视频文件 （.mov，.mp4，.avi等）在给定目录中显示它们 位置/路径和文件大小按文件大小降序排序 （从大到小）

    3. 我怎么写这个？

4 个答案:

答案 0 :(得分：8)

1）此脚本将目录和扩展名（不带“。”）作为参数，并为该目录和所有子目录中的所有文件提供总文件大小：

#!/bin/bash
DIR=$1
TYPE=$2
TOTAL=0    
FILES=`find $DIR -type f -iname "*.$TYPE"`
for f in $FILES; do
    if [ -f $f ]; then
        SIZE=`stat -c "%s" "$f"`
        TOTAL=$(($SIZE + $TOTAL))
    fi
done    
TOTALK=$(echo "scale=2; $TOTAL / 1024" | bc -l)
TOTALM=$(echo "scale=2; $TOTALK / 1024" | bc -l)
echo "Total file size for all \"$TYPE\" files: ${TOTAL}b / ${TOTALK}Kb / ${TOTALM}Mb"

输出：

[ 18:03 jon@hozbox ~/SO/bash ]$ ./linux-script-to-find-all-video-file-extensions-and-file-sizes.sh /home/jon/SO/python py
Total file size for all "py" files: 20062b / 19.59Kb / .01Mb

2）这个很有趣。它有优化的空间，但它完成了工作。唯一需要的参数是目录：

#!/bin/bash

# fill with more extensions or have it as a cmd line arg
TYPES=( mov mp4 avi )

DIR=$1

# Create a regex of the extensions for the find command
TYPES_RE="\\("${TYPES[1]}
for t in "${TYPES[@]:1:${#TYPES[*]}}"; do
    TYPES_RE="${TYPES_RE}\\|${t}"
done
TYPES_RE="${TYPES_RE}\\)"

# Set the field seperator to newline instead of space
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

# Generate output from path and size using: `stat -c "%s" filepath`
OUTPUT=""
for f in `find ${DIR} -type f -regex ".*\.${TYPES_RE}"`; do
SIZE=`stat -c "%s" ${f}`
    SIZEK=`echo "scale=2; ${SIZE} / 1024" | bc -l`
    SIZEM=`echo "scale=2; ${SIZEK} / 1024" | bc -l`
    OUTPUT=`echo ${SIZE}b / ${SIZEK}Kb / ${SIZEM}Mb - ${f}`";"$OUTPUT
done

# Reset IFS
IFS=$SAVEIFS

# Reverse numeric sort the output and replace ; with \n for printing
echo $OUTPUT | tr ';' '\n' | sort -nr

脚本在行动：

Bash Scripting Guide是我所知道的编写bash脚本的最佳资源之一。

man stat
man sort
man find
man bc
man tr

答案 1 :(得分：1)

以下是我对答案的看法：

find folder -type f -print0 | xargs -0 file --media-type | egrep 'image|video' | cut -f1 -d : | tr '\n' '\0'

以上将找到所有视频和图像。如果您参考@Adam的示例，则可以将此输出捕获到for循环中以生成您要查找的信息。最好将所有这些都放入脚本中。我在末尾包含tr'\ n''\ 0'，以便您可以使用-0参数将输出传递给xargs，以简化与其他命令的链接。如果你打算使用for循环包装器解决方案，那么tr就没有必要了（虽然它不需要处理特殊字符和引用文件名）

答案 2 :(得分：1)

  

xargs -0 file --media-type

- mime类型

答案 3 :(得分：0)

试试这些：

1 

for ext in $( find . -type f | sed -e 's#.*\(\.[a-zA-Z]*\)$#\1#' | sort | uniq ); do
    echo -n "${ext} "
    find . -type f -name "*${ext}" -ls | awk 'BEGIN { size=0; count=0 } { size+=$7; count++ } END { unit="B"; if (size > 1024*1024*1024) { size=size/(1024*1024*1024); unit="GB"; } else if (size > 1024*1024) { size=size/(1024*1024); unit="MB"; } else if (size > 1024) { size=size/1024; unit="kB"; } print "count: ", count, " size: ", size, unit }'
done

2 

find . -type f -name '*.java' -ls | sort -k +7 -r
