bash 转换为C代码,并编译为可执行文件

[root@localhost ~]# wget http://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.9.tgz

[root@localhost ~]# tar xvfz shc-3.8.9.tgz

[root@localhost ~]# cd shc-3.8.9

[root@localhost shc-3.8.9]# gcc -c shc.c

[root@localhost shc-3.8.9]# gcc -o shc shc.o

[root@localhost shc-3.8.9]# cp -a shc /bin/

[root@localhost ~]# shc -r -T -f wang.sh

[root@localhost ~]# gcc -c wang.sh.x.c

[root@localhost ~]# gcc -o wang wang.sh.x.o

将python代码转换为C代码

[root@localhost ~]# yum install -y epel-release

[root@localhost ~]# yum install -y python-pip

[root@localhost ~]# yum install -y python-dev*

[root@localhost ~]# pip install cython

[root@localhost ~]# vim lyshark.py

[root@localhost ~]# cython lyshark.py --embed

[root@localhost ~]# gcc `python-config --cflags` `python-config --ldflags` lyshark.c -o lyshark

C语言调用shell命令，并返回结果

#include

int main()

{

FILE * fp;

char buffer[1024];

fp=popen("free -h |grep 'Mem:' |awk '{print $2}'","r");

fgets(buffer,sizeof(buffer),fp);

printf("%s",buffer);

pclose(fp);

return 0;

}

#include "stdafx.h"

#include

int _tmain(int argc, _TCHAR* argv[])

{

char psBuffer[128];

FILE *pPipe;

char * wang;

pPipe = _popen("dir", "rt");

fgets(psBuffer, 128, pPipe);

printf("%s",psBuffer);

feof(pPipe);

system("pause");

return 0;

}
