对于较大的数字,我们可能希望以更具可读性的格式打印。以下示例与其他示例相同,但也以“人类”格式打印:
secs_to_human() {
if [[ -z ${1} || ${1} -lt 60 ]] ;then
min=0 ; secs="${1}"
else
time_mins=$(echo "scale=2; ${1}/60" | bc)
min=$(echo ${time_mins} | cut -d'.' -f1)
secs="0.$(echo ${time_mins} | cut -d'.' -f2)"
secs=$(echo ${secs}*60|bc|awk '{print int($1+0.5)}')
fi
echo "Time Elapsed : ${min} minutes and ${secs} seconds."
}
简单测试:
secs_to_human "300"
secs_to_human "305"
secs_to_human "59"
secs_to_human "60"
secs_to_human "660"
secs_to_human "3000"
输出:
Time Elapsed : 5 minutes and 0 seconds.
Time Elapsed : 5 minutes and 5 seconds.
Time Elapsed : 0 minutes and 59 seconds.
Time Elapsed : 1 minutes and 0 seconds.
Time Elapsed : 11 minutes and 0 seconds.
Time Elapsed : 50 minutes and 0 seconds.
要按照其他帖子中所述在脚本中使用(捕获起点,然后在结束时间调用该函数:
start=$(date +%s)
# << performs some task here >>
secs_to_human "$(($(date +%s) - ${start}))"
