本文實(shí)例為大家分享了C語言+shell實(shí)現(xiàn)linux網(wǎng)卡狀態(tài)檢測的具體代碼,供大家參考,具體內(nèi)容如下
成都創(chuàng)新互聯(lián)公司擁有10余年成都網(wǎng)站建設(shè)工作經(jīng)驗(yàn),為各大企業(yè)提供成都網(wǎng)站設(shè)計(jì)、成都做網(wǎng)站服務(wù),對于網(wǎng)頁設(shè)計(jì)、PC網(wǎng)站建設(shè)(電腦版網(wǎng)站建設(shè))、重慶APP開發(fā)、wap網(wǎng)站建設(shè)(手機(jī)版網(wǎng)站建設(shè))、程序開發(fā)、網(wǎng)站優(yōu)化(SEO優(yōu)化)、微網(wǎng)站、空間域名等,憑借多年來在互聯(lián)網(wǎng)的打拼,我們在互聯(lián)網(wǎng)網(wǎng)站建設(shè)行業(yè)積累了很多網(wǎng)站制作、網(wǎng)站設(shè)計(jì)、網(wǎng)絡(luò)營銷經(jīng)驗(yàn),集策劃、開發(fā)、設(shè)計(jì)、營銷、管理等網(wǎng)站化運(yùn)作于一體,具備承接各種規(guī)模類型的網(wǎng)站建設(shè)項(xiàng)目的能力。
不解釋,直接上代碼 要求linux環(huán)境具備grep和awk(awk可選)
#include#include #include #include int get_if_status(char *if_name) { char buffer[BUFSIZ]; char cmd[100]; FILE *read_fp; int chars_read; int ret =0; memset( buffer, 0, BUFSIZ ); memset( cmd, 0, 100 ); sprintf(cmd, "ifconfig -a | grep %s",if_name); read_fp = popen(cmd, "r"); if ( read_fp != NULL ) { chars_read = fread(buffer, sizeof(char), BUFSIZ-1, read_fp); pclose(read_fp); if (chars_read > 0) { ret = 1; } else { fprintf(stderr, "%s: NO FOUND\r\n",if_name); return 0; } } if(ret == 1) { memset( buffer, 0, BUFSIZ ); memset( cmd, 0, 100 ); sprintf(cmd, "ifconfig |grep %s",if_name); read_fp = popen(cmd, "r"); if ( read_fp != NULL ) { chars_read = fread(buffer, sizeof(char), BUFSIZ-1, read_fp); pclose(read_fp); if (chars_read > 0) { ret = 2; } else { fprintf(stderr, "%s: DOWN\r\n",if_name); return 1; } } } if(ret == 2) { memset( buffer, 0, BUFSIZ ); memset( cmd, 0, 100 ); sprintf(cmd, "ifconfig %s | grep RUNNING | awk '{print $3}'",if_name); read_fp = popen(cmd, "r"); if ( read_fp != NULL ) { chars_read = fread(buffer, sizeof(char), BUFSIZ-1, read_fp); pclose(read_fp); if (chars_read > 0) { fprintf(stderr, "%s: LINKED\r\n",if_name); return 3; } else { fprintf(stderr, "%s: UNPLUGGED\r\n",if_name); return 2; } } } return -1; } int main(int argc, char* argv[]) { int i=0; if(argc != 2) { fprintf(stderr, "usage: %s ", argv[0]); return -1; } i = get_if_status(argv[1]); printf( "if_status = %d\n", i ); return 0; }

測試結(jié)果
# ./netlink eth200 eth200: NO FOUND if_status = 0 # # ifconfig eth0 down # ./netlink eth0 eth0: DOWN if_status = 1 # # ifconfig eth0 up # ./netlink eth0 eth0: UNPLUGGED if_status = 2 # # ./netlink eth0 eth0: LINKED if_status = 3
以上就是本文的全部內(nèi)容,希望對大家的學(xué)習(xí)有所幫助,也希望大家多多支持創(chuàng)新互聯(lián)。
