写了个脚本把编译好的ffmpeg的头文件和库复制到系统目录下

感觉学shell得碰到啥问题现学现用，不专门去学。

#!/bin/sh

# directories
FAT="FFmpeg-iOS"
INSTALLLIBPATH="/usr/local/lib"
INSTALLINCLUDEPATH="/usr/local/include"

CWD=`pwd`
cd $FAT/lib
for LIB in *.a
do
   echo $LIB
   cd $CWD
   cp -rf $FAT/lib/$LIB $INSTALLLIBPATH/$LIB
done

cd $CWD
for dirlist in $(ls $FAT/include)
    do
       cp -rf $FAT/include/$dirlist $INSTALLINCLUDEPATH/$dirlist
       #cd ${dirlist}
       echo $FAT/include/${dirlist}
done
echo "ffmpeg install finished"

昨天发现cp -rf 复制jni.h会提示文件名太长，一长串的目录名加上jni.h，文件还是复制成功了。这个问题先留着。我把脚本改成挨个复制文件。shell脚本的格式要求真严格 if [ -d "$FAT/include/$dirlist" ] 这条语句这里if和[]之间要有空格 []这两边也要有空格，不然报错。另外在shell脚本中运行cp命令总出现No such file or directory ，我看了老外的讨论，按照他们的做法，运行成功了。cp有很多选项，覆盖选项，判断时间等选项的，但是我这里在测试不同版本的ffmpeg，干脆把文件夹和文件都删了再复制。
