日常工作中经常需要查看当前时间戳或者转换时间戳到日期,为此写了一个小工具,方便转换,分享给小伙伴,喜欢的请关注并点赞!
#include <stdio.h>#include <stdlib.h>#include <sys/types.h>#include <time.h>int main(int argc,char *argv[]) { ???time_t newtime; ???if (2 == argc) { ???????newtime = strtol(argv[1],NULL,10); ???????char szBuff[30]; ???????strftime(szBuff, sizeof(szBuff), "%Y/%m/%d %X", localtime(&newtime)); ???????printf("%sn",szBuff); ???} ???else { ???????time(&newtime); ???????printf("%ldn",newtime); ???} ???exit(0);}
编译
gcc -Wall -o showtime showtime.c
使用
chmod +x showtimecp showtime /usr/local/bin/showtimeshowtime 1624964738
