日常工作中經常需要查看當前時間戳或者轉換時間戳到日期，為此寫了一個小工具，方便轉換，分享給小夥伴，喜歡的請關注并點贊！
#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("%s\n",szBuff);
}
else {
time(&newtime);
printf("%ld\n",newtime);
}
exit(0);
}
編譯
gcc -Wall -o showtime showtime.c
使用
chmod x showtime
cp showtime /usr/local/bin/
