我编造了一些随机脚本，这是为了我的目的。
检查每个文件的数据

# !/bin/bash

dirname="$1"
tosearch="$2"
files=""

if [[ -s $dirname ]] ; then
    for filename in $(ls -d $dirname/*log); do
            count=$(bin/kafka-run-class.sh kafka.tools.DumpLogSegments --files "$filename" --print-data-log | grep "$tosearch" | wc -l)
            echo "$filename : $count"
    done
fi

集体检查所有文件中的数据

# !/bin/bash

dirname="$1"
tosearch="$2"
files=""

if [[ -s $dirname ]] ; then
    for filename in $(ls -d $dirname/*log); do
            files+="$filename,"
    done
    newfiles=$(echo "$files" | sed 's/,$//')
    count=$(bin/kafka-run-class.sh kafka.tools.DumpLogSegments --files "$files" --print-data-log | grep "$tosearch" | wc -l)
    echo "$count"
fi
