前言
还是理所当然的前言,我一直想找一套管理脚本的“框架”,能让自己杂乱的脚本有点规整,无奈眼界尚浅,未能找到。因此萌生自己写一点优化脚本的工具来,新手可学习,高手请指正。今天先写一个脚本的安装器,目的在于写完并新脚本之后能够在shell的任何位置都能够便捷使用。
config.ini主要用于配置两个目录。
递归遍历读取scriptPath目录下的脚本文件,排除掉install.sh和config.ini。
do_file()
{
for file in $1/*
do
if [[ -d "$file" ]]; then
do_file "$file"
else
basename=`basename $file`
if [[ ! $basename == "install.sh" && ! $basename == "config.ini" ]];then
link_file $file
fi
fi
done
}
为每一个脚本在binPath目录下创建软链接,如果之前存在则会首先删除掉,并对软链接加上执行权限(这里直接加了777)
link_file()
{
filePath=$1
fileName=`basename $1`
linkName=${fileName%.*}
linkPath=$binPath"/"$linkName
if [[ -L $linkPath ]];then
echo "===>(warn):"$linkPath" is exist,remove it!"
rm $linkPath
fi
ln -s $filePath $linkPath
echo "===>(info):link file "$filePath" -----> "$linkName" successful!"
chmod 777 $linkPath
}
把binPath目录添加到环境变量中(~/.bash_profile),这样就可以随时的访问脚本了~
add_profile()
{
isIn=`cat ~/.bash_profile | grep $1`
echo_test "isIn is "$isIn
if [[ x"$isIn" == x ]];then
echo "\n#Setting PATH FOR LOCAL SCRIPT" >> ~/.bash_profile
echo "export PATH=\"$1:\${PATH}\"" >> ~/.bash_profile
echo "===>(info)"$binPath" is added to bash_profile successful!"
export PATH=$1:${PATH}
else
echo "===>(info)"$binPath" is already in the bash_profile!<SKIP>"
fi
}
每次新加的脚本便可以放在scriptPath目录,执行install.sh之后便会在binPath里面生成对应的软链接,然后就可以在终端中自由的使用了~
1.可以看到,我的目录下面有五个文件(包括安装脚本的配置文件)
2.执行sh install.sh run 之后
3.在binPath目录下生成了三个软链接~
4.并在~/.bash_profile里生成了对应的Path
5.可以看到我们在Shell的任何位置已经可以是用自己编写的脚本指令了~(例如pyversion,是自己写的一个修改本地python版本的小脚本)
6.完整代码:
#!/bin/bash
# 读取config.ini
source ./config.ini
isTest=$isTest
binPath=$binPath
scriptPath=$scriptPath
editor(){
