#!/usr/bin/env bash

# 当前目录下，根据文件或目录的大小进行降序排序, 需要有对应目录的权限

# set current directory as default directory
dir=${1:-$(pwd)}
dir=$(echo $dir | sed -E 's/\/$//g')

IFSOld=$IFS
IFS=$'\n'
rs=""
for i in $(ls "${dir}"); do
    fpath="${dir}/$i"
    if [ -f "$fpath" ]; then
        size=$(du -B 1G "$fpath" | cut -f1)
        rs=$rs"\n[f]\x1c${size}\x1c$fpath"
    elif [ -d "$fpath" ]; then
        size=$(du -B 1G -c "$fpath" | grep total | cut -f1)
        rs=$rs"\n[d]\x1c${size}\x1c$fpath"
    fi
done
echo "block size = 1GB"
echo -e "\nFLG Block Path"
echo -e "-----------------------------------------------"
echo -e $rs | sort -t $'\x1c' -n -r -k2 | tr $'\x1c' ' '
IFS=$IFSOld

it also works

sep=$(echo -n -e '\x1c'); echo -e '2\x1cB\n1\x1cD' | sort -t $sep -n -k1

cat /dev/null > testfile
# 由于/dev/null文件不含有任何内容，通常用它来快速清除现有文件中的数据，而不用先删除文件再重新创建

$ cat p.sql
insert into table (name, age) values ('Jason', '24');
insert into table (name, age) values ('Guo', '29');

$ cat a.csv
