使用shell创建连续数字的目录

在给定目录下创建由数字组成的多个连续目录：

#!/bin/bash


base_dir=""

if test $# -lt 3 ; then
    echo "usage: $0 basedir detpth1_start_num deptth2_end_num depth2_dir_cnt"
    exit 1
fi

if test $2 -lt 0; then
    echo "start num can't less than 0"
    exit 0
fi

if test $2 -gt $3; then
    echo "end_num can't less than start num"
    exit 0
fi

base_dir="$1/"
base_dir=`echo $base_dir |sed 's/\/*$//g'`

for (( i = $2 ; i <= $3; i++ ));do
    hex=$i
    newpath="$base_dir/$hex"
    mkdir -p $newpath
done
