检查文件是否存在于给定目录中，而不是子目录中

Question

I have written a shell-script that basically looks for rar files and unrars them.

To avoid unraring the same file multiple times I added a check for the type of files I'll be unraring, namely *.avi, *.mkv and *.mp4.

find "/mnt/media1/TV Shows/" -type f -name "*.rar" -print0 | while IFS= read -r -d '' file; do
    DIR=$(dirname "${file}")
    MKV=$(find "${DIR}" -name "*.mkv" -print0)
    AVI=$(find "${DIR}" -name "*.avi" -print0)
    MP4=$(find "${DIR}" -name "*.mp4" -print0)
    if [ ! -f "$MKV" ] && [ ! -f "$AVI" ] && [ ! -f "$MP4" ]; then
            printf "UNRARING ${DIR}\n" >> /home/johan/unrarer.log
            sudo unrar e "${file}"
            MKV=$(find "${DIR}" -name "*.mkv" -print0)
            AVI=$(find "${DIR}" -name "*.avi" -print0)
            MP4=$(find "${DIR}" -name "*.mp4" -print0)
            if [ ! -f "$MKV" ] && [ ! -f "$AVI" ] && [ ! -f "$MP4" ]; then
                    printf "UNRAR FAILED\n" >> /home/johan/unrarer.log
            else
                    printf "UNRAR SUCCESSFUL\n" >> /home/johan/unrarer.log
            fi
    else
            printf "${DIR}: Found an mkv, avi or mp4 file, skipping\n" >> /home/johan/unrarer.log
    fi
done

Now, the problem is that most, if not all, directories have a "Sample" subdirectory with a video file in it. This file gets flagged with my current implementation, which is not what I desire.

I want it to look in the exact directory, $DIR , not any of its subdirectories.

Currently I have made a workaround where I simply delete the Sample directory if it exists, but this breaks torrents.

I have tried experimenting a bit with -wholename but I haven't found anything that works.

Any help appreciated.

Answer 1

Use the -maxdepth option to limit the find to the current directory.

MKV=$(find "${DIR}" -name "*.mkv" -print0 -maxdepth 0)
AVI=$(find "${DIR}" -name "*.avi" -print0 -maxdepth 0)
MP4=$(find "${DIR}" -name "*.mp4" -print0 -maxdepth 0)

charlton_austin 's answer held the answer. However it was -maxdepth 1.

Complete script:

find "/mnt/media1/TV Shows/" -type f -name "*.rar" -print0 | while IFS= read -r -d '' file; do
    DIR=$(dirname "${file}")
    cd "${DIR}"
    MKV=$(find . -maxdepth 1 -name "*.mkv" -print0)
    AVI=$(find . -maxdepth 1 -name "*.avi" -print0)
    MP4=$(find . -maxdepth 1 -name "*.mp4" -print0)
    if [ ! -f "$MKV" ] && [ ! -f "$AVI" ] && [ ! -f "$MP4" ]; then
            printf "UNRARING ${DIR}\n" >> /home/johan/unrarer.log
            sudo unrar e "${file}"
            MKV=$(find . -maxdepth 1 -name "*.mkv" -print0)
            AVI=$(find . -maxdepth 1 -name "*.avi" -print0)
            MP4=$(find . -maxdepth 1 -name "*.mp4" -print0)
            if [ ! -f "$MKV" ] && [ ! -f "$AVI" ] && [ ! -f "$MP4" ]; then
                    printf "UNRAR FAILED\n" >> /home/johan/unrarer.log
            else
                    printf "UNRAR SUCCESSFUL\n" >> /home/johan/unrarer.log
            fi
    else
            printf "${DIR}: Found an mkv, avi or mp4 file, skipping\n" >> /home/johan/unrarer.log
    fi
done

You can take advances of globbing:

if [[ "$(ls ./*.{mkv,avi,mp4} 2> /dev/null)" != "" ]]; then
    echo "exists"
else
    echo "fail"
fi

find isn't necessary here, since you are only looking for files with a given extension in the specified directory. Just fill an array using the pattern. It doesn't appear that you need to keep files of different types separate; you are just checking that something got unarchived.

cd "$DIR"
files=( "$DIR"/*.mkv "$DIR"/*.avi "$DIR"/*.mp4 )
if (( ${#files[@]} == 0 )); then
    printf "UNRARING $DIR\n" >> /home/johan/unrarer.log
    sudo unrar e "$file"
    files=( "$DIR"/*.mkv "$DIR"/*.avi "$DIR"/*.mp4 )
    if (( ${#files[@]} == 0 )); then
        printf "UNRAR FAILED\n" >> /home/johan/unrarer.log
    else
        printf "UNRAR SUCCESSFUL\n" >> /home/johan/unrarer.log
    fi
else
    printf "$DIR: Found an mov, avi, or mp4 file, skipping\n" >> /home/johan/unrarer.log
fi

If you are using bash 4 or later, you don't need to use find to find the rar files either:

shopt -s globstar
for file in "/mnt/media1/TV Shows/"**/*.rar; do
    ...
done
