I tried to create a log reproduction script at the time of apt install

I tried to create a log reproduction device at the time of apt install (I don't know if it will be useful, but you should feel the exhilaration of a successful installation ...)

For example, create `` test-update.shto reproduce the log atsudo apt-get update -y` as follows.

test-update.sh

#!/bin/bash
sudo apt-get update -y

The script for logging/reproducing is as replay.sh

https://github.com/seigot/replay_log

replay.sh

#!/bin/bash -x

set -e
set -u

IS_RECORD="n"
IS_REPLAY="n"
OUTPUT_LOG_FNAME="output.log"
TMP_LOG_FNAME="tmp.log"

# option
while getopts rp OPT
do
    case $OPT in
        "r" ) IS_RECORD="y"
          shift;;
        "p" ) IS_REPLAY="y"
          shift;;
    esac
done

if [ $IS_RECORD != "n"  ];then
    ############
    ##        ##
    ## record ##
    ##        ##
    ############
    echo "RECORD command:[$*], see $OUTPUT_LOG_FNAME"
    echo "$*" | xargs bash -c 'printf "%s %s\n" "$(date +%Y%m%d%H%M%S%N)" "$*"' bash 2>&1 | tee $OUTPUT_LOG_FNAME
    $* | xargs -L 1 bash -c 'printf "%s %s\n" "$(date +%Y%m%d%H%M%S%N)" "$*"' bash 2>&1 | tee $TMP_LOG_FNAME
    cat $TMP_LOG_FNAME >> $OUTPUT_LOG_FNAME
    rm $TMP_LOG_FNAME
    echo "record replay log: $OUTPUT_LOG_FNAME"

elif [ $IS_REPLAY != "n"  ];then
    ############
    ##        ##
    ## replay ##
    ##        ##
    ############
    echo "REPLAY command:[`head -1 $OUTPUT_LOG_FNAME`]"
    PREV_TIME=`head -1 $OUTPUT_LOG_FNAME | cut -d' ' -f1`
    while read line; do
    CURRENT_TIME=`echo $line | cut -d' ' -f1`
    TMP=`echo $((CURRENT_TIME-PREV_TIME))`
    TIME_DIFF=`echo "scale=5; $TMP / 1000000000.0" | bc`
    PREV_TIME=$CURRENT_TIME
    COMMAND_LOG=`echo $line | cut -d' ' -f2-`

    #echo "$TIME_DIFF $COMMAND_LOG"
    echo "$COMMAND_LOG"
    sleep $TIME_DIFF

    done < $OUTPUT_LOG_FNAME
fi

Log

Specify the execution command with -r (example: bash test-update.sh)

$ bash replay.sh -r "bash test-update.sh"
RECORD command:[bash test-update.sh], see output.log
...

Reproduce the log

If you specify the -p option in bash replay.sh, the recorded log will be reproduced.

$ bash replay.sh -p
REPLAY command:[20201230225127118529673 bash test-update.sh]

I would appreciate it if you could teach me if there is anything useful.

Remarks

I want to create a demo machine

Location and confirmation method of operation log of apt command Display history done by apt [bash] File output with time added to error content Prepend output date and time to standard output How to time stamp each standard output without changing the program and sample in Python I want to take the full date to milliseconds with the date command! Optional analysis with bash bash: standard output and standard error are output to log
