Question

我使用Linux而且我是新编码的人，我需要项目帮助。

#!/bin/bash
# findName.sh - written by Corey Brown
#
# for use in some project
File="/acct/common/CSCE215-Fall17"

if [[ $1 = "" ]] ; then
    echo "usage: `basename $0` [only_one_argument]"
    exit 2
fi

# read the file line by line
while read LINE
do
    # file format: First, Middle, Last, UserID
    # set the index values based on the line format given above
    firstNameIndex=0
    middleNameIndex=1
    lastNameIndex=2
    userIDIndex=3

    # read the line into an array
    IFS=', ' read -r -a lineArray <<< "$LINE"

    # if the passed parameter equals the value of the line at userIDIndex
    if [[ $1 -eq ${lineArray[$userIDIndex]} ]] ; then
        echo ${lineArray[$firstNameIndex]} ${lineArray[$middleNameIndex]} ${lineArray[$lastNameIndex]}
        exit 1
    fi

done < "$File"

目标是搜索用户ID，并找到与之关联的名称。我正在搜索的文件格式为FirstName,MiddleName,LastName,UserID。有78行都具有不同的用户ID和名称。这是文件：

这就是代码，现在当我运行脚本并传入一个参数时，它总是会给我列表中的第一行：

$ ./findName.sh zds
$ Adarius Macarthy Adams
$

当我没有通过论证时，它打印出整个列表。我参与了指数，但我无法弄清楚我哪里出错了。

搜索userID并返回该行上的名称
