Shell 批量生成链接

linux程序安装完执行总是要全路径去执行，每一个添加到PATH 又太麻烦，干脆将其生成链接到 ~/bin 目录下，在 /etc/profile 追加一句 export PATH="$PATH:~/bin" ，

#!/bin/bash
#批量生成链接 <1058436713@qq.com>
# 使用 ./xxx.sh [-s] dir [default="~/bin"]

var=""
BIN_DIR=""
if [ "$1" = "-s" ];then
    var="true";shift
fi

if [ -z "$1" ] || [ ! -d $1 ];then
    echo "Parameter error: \$1";exit 1;
fi


if [ -z "$2" ];then
    if [ ! -d ~/bin ];then
        mkdir ~/bin
    fi
    BIN_DIR=~/bin
elif [ -n "$2" ] && [ -d $2 ];then
    BIN_DIR=$2
else
    echo "Parameter error: \$2";exit 2; 
fi


for file in `ls -al $1 | grep "^-" | gawk '{printf("%s ",$9)}'`;do
    if [ "$var" = "true" ];then
        ln -s $1/$file $BIN_DIR/$file
    else
        ln $1/$file $BIN_DIR/$file
    fi
done
