从播放列表文件中批量重命名视频文件

  • 772

目录中的文件：

$ ls | sort -n

1.mp4
2 .mp4
3 .mp4
4 .mp4
5 .mp4
6 .mp4
7 .mp4
8 .mp4
9 .mp4
10 .mp4

播放列表文件中的文件名列表：

$ cat playlist.m3u8

1- Introduction-OxIDLw0M-m0.mp4
2 - How React Works-pKYiKbf7sP0.mp4
3 - React Setup (with CDN)-SAX6RMEFVM4.mp4
4 - React Components-Fis_Q3rkgtM.mp4
5 - State-yuN4EMjR4K4.mp4
6 - React Dev Tools--XQ2zCdxw0I.mp4
7 - DOM Events--ZB8I2PmiOw.mp4
8 - Changing State (and 'this')-XJzDF9bj368.mp4
9 - Intro to Forms-BVbdZ1133JU.mp4
10 - Create React App-5QwNCX3UbXc.mp4

文件名以数字开头。如何通过播放列表文件中列出的名称及其相应的数字重命名目录中的文件，结果将是：

$ ls | sort -n


1- Introduction-OxIDLw0M-m0.mp4
2 - How React Works-pKYiKbf7sP0.mp4
3 - React Setup (with CDN)-SAX6RMEFVM4.mp4

5 - State-yuN4EMjR4K4.mp4

  1. Best Answer
    while read -r i ; do
    file=$(echo $i | cut -d- -f1).mp4
    if [ -e "$file" ]; then
        mv "$file" "$i"
    fi      
done < playlist.m3u8

    for i in ?*.mp4; do
    mv "$i" "$(grep -xm1 "${i%.*}"'-.*\.mp4' playlist.m3u8)"
done

  2. 如果你有bash4+，这是使用mapfileaka的一种方法readarray

    #!/usr/bin/env bash

shopt -s nullglob

rawfiles=(*.mp4)
mapfile -t files < <(printf '%s\n' "${rawfiles[@]}"| sort -n)
mapfile -t playlistfile < <(sort -n playlist.m3u8)

for i in "${!files[@]}"; do
   mv -v  "${files[$i]}" "${playlistfile[$i]}"
done

    Linux 上的输出

    renamed '1.mp4' -> '1- Introduction-OxIDLw0M-m0.mp4'
renamed '2 .mp4' -> '2 - How React Works-pKYiKbf7sP0.mp4'
renamed '3 .mp4' -> '3 - React Setup (with CDN)-SAX6RMEFVM4.mp4'
renamed '4 .mp4' -> '4 - React Components-Fis_Q3rkgtM.mp4'
renamed '5 .mp4' -> '5 - State-yuN4EMjR4K4.mp4'
renamed '6 .mp4' -> '6 - React Dev Tools--XQ2zCdxw0I.mp4'
renamed '7 .mp4' -> '7 - DOM Events--ZB8I2PmiOw.mp4'
renamed '8 .mp4' -> '8 - Changing State (and '\''this'\'')-XJzDF9bj368.mp4'
renamed '9 .mp4' -> '9 - Intro to Forms-BVbdZ1133JU.mp4'
renamed '10 .mp4' -> '10 - Create React App-5QwNCX3UbXc.mp4'

    这是单线器

    rawfiles=(*.mp4); mapfile -t files < <(printf '%s\n' "${rawfiles[@]}"| sort -n); mapfile -t playlistfile < <( sort -n playlist.m3u8); for i in "${!files[@]}"; do  mv -v  "${files[$i]}" "${playlistfile[$i]}"; done

  3. 你可以paste这样使用：

    paste <(ls -1 *mp4 | sort -n) playlist.m3u8  | sed 's,\t,\t",' | sed 's,^,",' | sed 's,mp4,mp4",g' | xargs -L1 mv

    结果：

    $ ll
total 4.0K

-rw-r--r-- 1 ja users   0 Feb 24 15:09 1- Introduction-OxIDLw0M-m0.mp4

    尽管在这种特殊情况下它会起作用，但请注意解析 ls 的输出并不是一个好主意。
