bash - 为什么我的 bash 脚本中不断出现语法错误？它是否与 ":"相关？

Question

我正在尝试计算 errorList 数组中每个项目的错误，但我不断收到“表达式中的语法错误(错误标记是“:只是一个测试”)”。

#!/bin/bash

declare -a errorList=(
    'MEDIA ERROR: just a test'
    'MEDIA BLA: resource unavaliable!'
    'DIALOG: Found PROBLEM ev_id="EV_ID"'
    )

declare -a errorListNames=(
    "Silence"
    "Unavaliable"
    "Environment error"
    )

pathLogs="/home/logs_test/"
logFileName="media.log.*"

dateLog="10-10-2019"

fgrep "$dateLog" $pathLogs$logFileName > grepedByDate.txt

for i in "${errorList[@]}"
    do
        fgrep -c "${ errorList[i], }" grepedByDate.txt
        echo "${errorListNames[i]}"
    done

echo "Bye"

Answer 1

1. 使用!或 #获取 key

代替:

for i in "${errorList[@]}"

采用:

for i in ${!errorList[@]}"

或者:

maxIndex=${#errorList[@]}
for (( i=0; i<$maxIndex; i++ ))

2. 空格在变量引用中很重要

代替:

        fgrep -c "${ errorList[i], }" grepedByDate.txt

采用:

        fgrep -c "${errorList[i]}" grepedByDate.txt
