使用 grep 從文本文件中提取帶有表達式的文本

我的文本文件中有以下兩行，並希望以分鐘為單位計算這些行 X 和 Y 之間的持續時間。

line X:  18.05.2022 13:54:52 [ INFO]: Starting Component 'OWN_FUNDS_RULES' (5/15)
line Y:  18.05.2022 14:28:22 [ INFO]: Finished Component 'OWN_FUNDS_RULES_CONSOLIDATION' (6/15) with SUCCESS - 00:07:05.119

我有以下程式碼將持續時間返回為零。

cd /logs/

Header="OFRComponentCalculation"
echo $Header >OutputFile.csv
for file in log_Job_*/process.log; do

   ### OFRComponentCalculation ###
   {
       OFRS="$(grep 'Starting Component*OWN_FUNDS_RULES*' "$file" | awk '{print $3,$4}' | cut -d: -f2-)"
       OFRE="$(grep 'Finished Component*OWN_FUNDS_RULES_CONSOLIDATION*' "$file" | awk '{print $1,$2}' | cut -d: -f1-)"

       convert_date() { printf '%s-%s-%s %s' ${1:6:4} ${1:3:2} ${1:0:2} ${1:11:8}; }

       # Convert to timestamp
       OFRS_TS=$(date -d "$(convert_date "$OFRS")" +%s)
       OFRE_TS=$(date -d "$(convert_date "$OFRE")" +%s)

       # Subtract
       OFRD=$((OFRS_TS - OFRE_TS))
       # convert to HH:MM:SS (note, that if it's more than one day, it will be wrong!)
       OFRComponentCalculation=$(date -u -d "@$OFRD" +%H:%M:%S)
       echo "$OFRComponentCalculation"
   }
   Var="$OFRComponentCalculation"
   echo $Var >>OutputFile.csv

done

我懷疑在為這 2 行編寫 grep commangs 時搞砸了一些東西，任何人都可以幫助我。

這應該為你做：

:~$ cat event.log
18.05.2022 13:54:52 [ INFO]: Starting Component 'OWN_FUNDS_RULES' (5/15)
18.05.2022 14:28:22 [ INFO]: Finished Component 'OWN_FUNDS_RULES_CONSOLIDATION' (6/15) with SUCCESS - 00:07:05.119

:~$ cat calc_time.sh
#!/bin/bash
file="$1"

OFRS="$(grep "Starting Component 'OWN_FUNDS_RULES'" "$file" | cut -d ' ' -f1,2)"
OFRE="$(grep "Finished Component 'OWN_FUNDS_RULES_CONSOLIDATION'" "$file" | cut -d ' ' -f1,2)"

function date_time {
       time_frame=$1
       day=$(echo $time_frame | cut -d '.' -f1 )
       month=$(echo $time_frame | cut -d '.' -f2 )
       year=$(echo $time_frame | cut -d '.' -f3 | cut -d ' ' -f1)
       hour=$(echo $time_frame | cut -d ' ' -f2 | cut -d ':' -f1)
       minute=$(echo $time_frame | cut -d ' ' -f2 | cut -d ':' -f2)
       second=$(echo $time_frame | cut -d ' ' -f2 | cut -d ':' -f3)
}

date_time "$OFRS"
sdate=$(date -d "$year"-"$month"-"$day"T"$hour":"$minute":"$second" +%s)
date_time "$OFRE"
fdate=$(date -d "$year"-"$month"-"$day"T"$hour":"$minute":"$second" +%s)

#Substraction
Exec_time=$(($fdate-$sdate))

echo Time of execution in seconds: $Exec_time
# convert to HH:MM:SS (note, that if it's more than one day, it will be wrong!)
OFRComponentCalculation=$(date -u -d "@$Exec_time" +%H:%M:%S)
echo "$OFRComponentCalculation"

然後，您可以將該文件作為參數執行它：

:~$ bash calc_time.sh event.log
Time of execution in seconds: 2010
00:33:30
