本文介绍了一种使用Shell脚本生成特定格式随机时间的方法。通过一系列的数学运算和字符串操作，该脚本能够生成类似'月日时:分:秒'格式的随机时间戳。
#生成随机时间
h1=`echo "scale=1; ($RANDOM/32767)*1.9" | bc|cut -b 1-1`
h2=`echo "scale=1; ($RANDOM/32767)*9.9" | bc|cut -b 1-1`
m1=`echo "scale=1; ($RANDOM/32767)*5.9" | bc|cut -b 1-1`
m2=`echo "scale=1; ($RANDOM/32767)*9.9" | bc|cut -b 1-1`
s1=`echo "scale=1; ($RANDOM/32767)*5.9" | bc|cut -b 1-1`
s2=`echo "scale=1; ($RANDOM/32767)*9.9" | bc|cut -b 1-1`
begin_time=`echo ${d_month} ${d_day} ${h1}${h2}:${m1}${m2}:${s1}${s2}`
h1=`echo "scale=1; ($RANDOM/32767)*1.9" | bc|cut -b 1-1`
h2=`echo "scale=1; ($RANDOM/32767)*9.9" | bc|cut -b 1-1`
m1=`echo "scale=1; ($RANDOM/32767)*5.9" | bc|cut -b 1-1`
m2=`echo "scale=1; ($RANDOM/32767)*9.9" | bc|cut -b 1-1`
s1=`echo "scale=1; ($RANDOM/32767)*5.9" | bc|cut -b 1-1`
s2=`echo "scale=1; ($RANDOM/32767)*9.9" | bc|cut -b 1-1`
begin_time=`echo ${d_month} ${d_day} ${h1}${h2}:${m1}${m2}:${s1}${s2}`
