Bash脚本为所有文件预先添加一个随机数

不,这不难做到。但是,它会弄乱您精心编制的文件名,并且可能很难撤消。

$RANDOM 作为bash中随机数的简单来源。为了你的

#!/bin/bash
for file in *; do
  mv "$file" $RANDOM-"$file"
done

我没有测试这个。你可能想在一些小的 样品,以确保你知道它做什么。

这个脚本将洗牌文件和重新洗牌,如果他们已经洗牌。如果你把它当作 -u

#!/bin/bash
for file in *.mp3
do
    if [[ -d $file ]]
    then
        continue    # skip directories
    fi
    if [[ $file =~ ^1[0-9]{5}9-(.*).mp3$ ]]    # get basename
    then
        name=${BASH_REMATCH[1]}                # of a previously shuffled file
    else
        name=${file%.mp3}                      # of an unshuffled file
    fi
    if [[ $1 != -u ]]
    then
        mv "$file" "1$(printf "%05d" $RANDOM)9-$name.mp3"    # shuffle
    else
        if [[ ! -e "$file.mp3" ]]
        then
            mv "$file" "$name.mp3"                           # unshuffle
        fi
    fi
done

它在“1”后使用固定宽度的五位数随机数,后跟“9-”,因此无序排列的文件名的形式如下: 1ddddd9-filename maybe with spaces - and other stuff.1983.mp3 .

如果重新运行脚本,它将通过更改前缀中的随机数来重新排列文件。

-u型 参数将删除 1ddddd9-

脚本需要Bash>=版本3.2。

for i in *; do mv "$i" $RANDOM-"$i"; done

#!/bin/bash
#
# FILE: 
#   prepend_random_num.sh
# ABOUT: 
#   Prepends a random number between 1-65000 and an underscore to all files of specified type
#   Runs on Mac OSX & Linux
# EXAMPLE: 
#   $ ls 
#   a.jpg    b.jpg
#   $ sh prepend_random_num.sh jpg
#   $ ls
#   138_b.jpg    8474_a.jpg    

for file in *.$1
do
  rand=$(jot -r 1 1 65000 || shuf -i 1-65000 -n 1)
  mv "$file" "$rand"_"$file"
done

通过这个shell,您的音乐库将随机播放,在播放完所有歌曲之前不会重复任何歌曲。 “播放歌曲的历史记录记录在文件中” 如果您向音乐库中添加了一首歌曲,或者已经听过库中的所有歌曲,则会自动重置此历史记录,从而生成一个新的随机列表。只要您愿意,您就可以重置历史记录“正在删除文件” . “他的”。

#!/bin/bash

#Through this shell, your music library will be played randomly, without repeating any songs until all have been played. 
#The history of songs played is recorded in the file "*. Sh.his". 
#This history is reset automatically if you added a song to the music library or have already heard all the songs of your library, 
#generating a new random list ever. Whenever you want you can reset the history is deleting the file "*. Sh.his".

#Press "q" to skip song
#Press "p" to pause song and resume song

cadena=$(find "$path" -iname '*.mp3')                                   #search media files
nmedia=$(echo "$cadena" | wc -l)

if [ -f "$0.his" ]                                          #file exist

我知道这已经很老了,但我也遇到了类似的问题,也许这仍然有用。我刚买了一个便宜但防水的MP3播放器,它可以正常运行,只是在洗牌模式下,同样的几首歌似乎一直在重复。我在上面找到一些说明 LinuxQuestions.org

我创建了一个名为Running的文件夹,并把我所有的mp3从我的跑步播放列表放在那里(我将文件夹名称大写,以免意外删除。)

 #!/bin/bash
 mkdir ../running_random
 for fname in *.mp3
 do
         cp "$fname" ../running_random/$RANDOM."$fname".mp3
 done

我从Running目录中调用脚本,将新创建的Running\u random目录中的内容复制到MP3播放器中,然后删除Running\u random。
