linux下查找实用技巧

时间：2010-09-06 来源：mrchenlang

linux下文件很多，有时候找起来很麻烦，下面介绍两条非常使用的查找技巧： 1.查找文件 find 例： find /etc -name profile //查找 /etc下名为 profile 的文件

chen@chen:~$ find /etc -name profile
find: `/etc/ppp/peers': Permission denied
/etc/profile
find: `/etc/cups/ssl': Permission denied
find: `/etc/chatscripts': Permission denied
find: `/etc/ssl/private': Permission denied
/etc/firefox/profile

有的文件可能存在权限问题！利用通配符查找查找 /etc 下包含 profile的文件名

chen@chen:~$ find ./test/ -name "*led*"
./test/mmu/leds.o
./test/mmu/leds.c

查找字符例： grep -rnH "printf" /home/chen/test/ //在 /home/chen/test 下递归查找包含"printf"的字符

chen@chen:~$ grep -rnH printf ./test/
./test/hello.c:6: printf("hello!\n");
./test/macro.c:10: printf("The file is %s\n",__FILE__);
./test/macro.c:11: printf("The file is %d\n",__LINE__);
./test/macro.c:12: printf("The file is %s\n",__FUNCTION__);
./test/macro.c:14: printf("The file is %s\n",__DATE__);
./test/macro.c:15: printf("The file is %s\n",__TIME__);
./test/macro.c:16: printf("%s""%s""\n",__FILE__,__TIME__);
./test/max.c:7: printf("%d\n",MAX(3,4));
./test/make/chenlang.c:5: printf("Hello! I am chenlang!\n");
./test/stuct_test.c:15: printf("%d\n",sizeof(struct A));
./test/heap.c:8: printf("%x\n",&p);
./test/heap.c:9: printf("%x\n",&p+1);
./test/heap.c:10: printf("%x\n",&p+2);
./test/test.c:18: //printf("please input passwd!\n");
./test/test.c:24: printf("%s\n",passwd);
./test/test.c:25: printf("%s\n",ptr);*/
./test/test.c:39: printf("recv signal\n");
