Linux 回收站——防止误删文件

方法 1：bash 脚本（写入~/.bashrc 文件），简单实用无外部依赖

提供如下四个命令：

rmv a <b c>：move a <b and c> to recycle bin
unrmv a <b>: restore a from recycle bin to <b> (default b='./') 
lsrmv: list recycle bin
clearrmv: clear recycle bin

# >>> zzh: recycle bin >>>
## define trash dir and make it
# trash_path="~/.trash"
# trash_path="$HOME/.trash"
trash_path="/hhd/2/zzh/.trash/" # # assign one according to your need
# make the $trash_path dir if there is no one.
if [ ! -d $trash_path ]; then
    mkdir -p $trash_path
fi

## define alias
alias rmv=trash           # rmv a <b c>：move a <b and c> to recycle bin
alias unrmv=restorefile   # unrmv a <b>: restore a from recycle bin to <b> (default b='./')
alias lsrmv=lstrash       # lsrmv: list recycle bin
alias clearrmv=cleartrash # clearrmv: clear recycle bin

## functions
# move to recycle bin
trash() {
    if [[ $# -le 0 ]]; then
        echo "please assign the parameters: delete_file"
        return
    fi

    for i in $*; do
        STAMP=$(date "+%Y-%m-%d")
        file_srcpath=$(echo $i | sed 's/\(.*\)\/$/\1/g')
        file_dstpath=$trash_path/$STAMP/$file_srcpath

        if [[ -e $file_dstpath ]]; then
            suffix=$(date "+%Y%m%d%H%M%S")
            file_dstpath=${file_dstpath}_${suffix}
        fi

        file_path_dir=$(dirname $file_dstpath)
        mkdir -p $file_path_dir
        mv $file_srcpath $file_dstpath
    done
}

# restore from recycle bin
restorefile() {
    if [[ $# -eq 1 ]]; then
        trash_file=$1
        restore_dir="./" # default restore dir = ./
    elif [[ $# -eq 2 ]]; then
        trash_file=$1
        restore_dir=$2
    else
        echo "please assign the parameters: trash_file <restore_dir>"
        return
    fi

    restore_to_path=$restore_dir/${trash_file:11}
    if [[ -d ${restore_to_path} ]]; then
        echo "mv -b $trash_path/$trash_file/* $restore_to_path"
        mv -b $trash_path/$trash_file/* $restore_to_path
    else
        trash_file_dir=$(dirname $trash_file)
        restore_to_dir=$restore_dir/${trash_file_dir:11}/
        mkdir -p $restore_to_dir
        echo "mv -b $trash_path/$trash_file $restore_to_dir"
        mv -b $trash_path/$trash_file $restore_to_dir
    fi

    find $trash_path -mindepth 1 -depth -type d -empty -delete # delete empty dirs
}

# show recycle bin contents
lstrash() {
    dirs=$(find $trash_path -type d -links 2)
    files=$(find $trash_path -maxdepth 2 -mindepth 2 -type f)
    printf "\n------ Dirs ------\n"
    while read -r line; do
        echo "${line/$trash_path/}"
    done <<<"$dirs"
    printf "\n------ Files ------\n"
    while read -r line; do
        echo "${line/$trash_path/}"
    done <<<"$files"
}

# clear recycle bin
cleartrash() {
    read -p "Sure to clear the trash box?[y/n]" confirm
    [[ $confirm == 'y' ]] || [[ $confirm == 'Y' ]] && /bin/rm -rdf $trash_path/*
}

# <<< zzh: recycle bin <<<

如果需要定期清理回收站，可以使用 Linux 的定时任务命令 crontab 定期删除 trash 目录，但是不建议这么做，因为 rm 命令有风险（惨痛教训！），还是自己需要的时候手动运行命令 clearrmv 清理回收站比较好。

方法 2：开源命令行工具，功能更全面
