Bash 脚本更改动态变量上的文件夹路径的一部分

C0nw0nk

所以我把下面的 bash 脚本放在一起，我想修改我抓取的文件路径目录

所以我的布局是这样的

/home/videos_test/categoryname/1/vid.mp4
/home/videos_test/categoryname/2/randomvid.mp4

我想修改它抓取的文件路径，看起来像这样

/home/videos_test/changed_folder/1/vid.mp4
/home/videos_test/changed_folder/2/randomvid.mp4

完整脚本

#!/bin/bash

echo "Type the category that you want, followed by [ENTER]:"

read category

export FILE_PATH="/home/videos_test"
export STAR="/*"

FILE_PATH=$FILE_PATH"/"$category;
echo $FILE_PATH;

minimumsize=1000

for dir in $FILE_PATH$STAR$STAR; do
[[ ! -f "${dir}" ]] && continue # if its NOT a file then skip
actualsize=$(du -k "$dir" | cut -f 1)
if [[ ! $actualsize -ge $minimumsize ]]; then #if file is less than 1mb delete it

echo $dir
echo size is under $minimumsize kilobytes
rm "$dir"
echo deleted

else #for files over 1mb in size convert with ffmpeg

full_file=$(basename $dir)
full_dir=$(dirname $dir)
echo $full_file
echo $full_dir

ffmpeg -i "$dir"

#ffmpeg output file directory needs to be mirrored but with a folder change

read -p "Press any key to resume ..."

fi
done

我想成为 ffmpeg 的文件夹输出

 /home/videos_test/$category _new/1/vid.mp4
/home/videos_test/$category _new/2/randomvid.mp4

C0nw0nk

path_start=$(echo $dir | rev | cut -d'/' -f4- | rev)
path_end=$(echo $dir | cut -d'/' -f5-)
new=_new
new_path=$path_start/$category$new/$path_end
new_path_no_file=$(echo $new_path | rev | cut -d'/' -f2- | rev)
mkdir -p $new_path_no_file
ffmpeg -i "$dir" -c:v copy -c:a copy -x264opts opencl -movflags +faststart -analyzeduration 2147483647 -probesize 2147483647 -pix_fmt yuv420p "$new_path"
