如果找不到时间，应该告诉下一次日志中可用的时间

Question

是否有任何时间函数，可以检查时间，如果找不到的话，请告诉我们下一个可用的日期。

#!/bin/bash
read -p " enter the App name : " app
file="/logs/$app/$app.log"
if ! [ -f "$file" ]; then
    echo "$app.log not found, Please check correct log name in deployer"
    exit
fi
format=$(head -1 $file | awk '{print $1,$2,$3}')
format1=$(tail -1 $file | awk '{print $1,$2,$3}')
read -p " Enter the Date in this Format --'$format' : " first
until grep -q "$first" "$file"
do
  echo "Date not found"
  read -p " Enter the Date in this Format --'$format' : " first
done
final_first=$first
echo "logs are present till this '$format1' date, use this date if you want logs from Provided to latest."
read -p "Enter the end date : " end
until grep -q "$end" "$file"
do
  echo "Date not found"
  read -p "Enter the end date : " end
done
final_end=$end
cd /logs/$app
sed -n " /$final_first/,/$final_end/ "p $file >$app.txt
zip $app.zip $app.txt
rm $app.txt  

输出是

./app_log_extract 
 enter the App name : cspt
 Enter the Date in this Format --'Sep 08 04:53:30' : Sep 08 05
Date not found
 Enter the Date in this Format --'Sep 08 04:53:30' : 

现在，我想和"找不到的日期"一道，日志从9月08 20:09:39

出现。

日志文件是

AWK工具主要用于以有用的方式报告一些数据。在这些开始和结束块的情况下，输出将含义更少，此处未定义最终块。调试此代码

类似的东西可能会有所帮助：

format="Sep 08 05" # actually, this is swt by user input.
read month_in date_in time_in <<< "$format"
awk '
BEGIN {
    split("Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec",month)
    for (i in month) {
        month_nums[month[i]]=i
    }
}
(month_nums[$1] >= month_nums[month_in]) && ($2>=date_in) && ($3>=time_in){
    print "logs are available from " $1, $2, $3;
    exit 0;   
}
' "month_in=$month_in" "date_in=$date_in" "time_in=$time_in" logfile
