Question

我有一个包含

的文本文件（particulars.txt）

PERSONID，PERSONNAME，employmentType

particulars.txt

1,jane,partTime
2,bob,fullTime
3,john,fullTime

如何操作，如果我输入工作人员的名字，它将检查该人是全职或兼职工作人员并提示用户输入工资并重写回文件对那个人。我会详细解释。

例如

Enter Name:jane 
jane is a partTime staff
Enter Hourly Salary:10

所以textfile（particulars.txt）现在将是

1,jane,partTime,10
2,bob,fullTime
3,johnfullTime

示例二

Enter Name:bob
bob is a fullTime staff
Enter monthly Salary:1600

所以textfile（particulars.txt）现在将是

1,jane,partTime,10
2,bob,fullTime,1600
3,john,fullTime

这就是我所拥有的我的代码

#!/bin/bash
fileName="particulars.txt"
read -p "Enter name:" name
if grep -q $name $fileName; then
     employmentType=$(grep $name $fileName | cut -d, -f4)
     echo "$name is $employmentType" staff"
     if [ $employmentType == "partTime" ]; then
          echo "Enter hourly pay:" 
          read hourlyPay
          #calculations for monthly salary(which I have not done)

     elif [ $employmentType == "fullTime" ]; then
          echo "Enter monthly salary:" 
          read monthlySalary         
     fi    
else 
    echo "No record found"
fi

read -p "Press[Enter Key] to Contiune.." readEnterKey

我只能找到这个人所属的雇佣类型，但我不知道如何/我应该怎样做才能在该行的最后为该特定的人添加薪水。我已经阅读了sed，但我仍然对如何使用sed来实现我的结果并因此寻求你们的帮助感到困惑。提前致谢

Answer 1

除非您需要以交互方式进行，否则您可以说：

sed '/\bbob\b/{s/$/,1600/}' filename

这会将,1600添加到与bob匹配的行中。请注意，通过指定字词边界\b，您可以确保仅对bob而非abob或boba进行更改。

您可以使用-i选项对文件进行就地的更改：

sed -i '/\bbob\b/{s/$/,1600/}' filename

编辑：为了使用shell变量，请对sed命令使用双引号：

 sed "/\b$employeeName\b/{s/^$/,$monthlySalary/}" filename

我刚修改了你的剧本。

#!/bin/bash
fileName="particulars.txt"
read -p "Enter name:" name
if grep -q $name $fileName; then
     employmentType=$(grep $name $fileName | cut -d, -f3)
     emp_name=$(grep $name $fileName | cut -d, -f2)  # Getting emp name
     emp_id=$(grep $name $fileName | cut -d, -f1)    # Getting id
     echo "$name is $employmentType staff"
     if [ $employmentType == "partTime" ]; then
          echo "Enter hourly pay:" 
          read hourlyPay
          #calculations for monthly salary(which I have not done)
          sed -i "s/^$emp_id.*$/&,$hourlyPay/g" $fileName  # Modifying the file by using id.

     elif [ $employmentType == "fullTime" ]; then
          echo "Enter monthly salary:" 
          read monthlySalary
     fi
else
    echo "No record found"
fi

read -p "Press[Enter Key] to Contiune.." readEnterKey

我添加了以下几行。

emp_id=$(grep $name $fileName | cut -d, -f1)
emp_name=$(grep $name $fileName | cut -d, -f2)
sed -i "s/^$emp_id.*$/&,$hourlyPay/g" $fileName

将特定字符串添加到末尾的特定行。 -bash
