在linux里面，现在有一个可执行的文件，名字是aas，还有个文本文件是sps，现在想要这个功能：
首先修改sps文件内容，把srfn行的01改成02，sfn行的001改成002，保存；
执行aas文件（我不知道这个aas是什么语言写的，但是运行的时候不需要加./ ，只用在当前目录输入aas就可以运行了）。
再打开sps文件修改02为03，修改002为003，保存；
执行aas文件；
循环上面的步骤，直到18为止。

文件内容乱了，重新发一下：
12345678901234567890123456789012345678901234567890
dx=50%%%type=b%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
srfn=ny-89-02-sr.prn%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
sfn=002s.prn%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
rfn=r_wt_all.r%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
脚本如下：
#！/bin/bashfor((i=2;i<=18;i++))
do
sed -i 's/srfn=ny-89-.*-sr/srfn=ny-89-0'"$i"'-sr/g' sps
sed -i 's/sfn=00.*prn/sfn=00'"$i"'\.prn/g' sps
aas
done
