在shell脚本中从命令行和函数中传递参数

I want know weather it is possible to pass arguments from command line and from the function inside a shell script

我想知道是否可以从命令行和shell脚本中的函数中传递参数

I know its is possible to pass a argument from command line to shell script using

我知道可以使用命令行将参数传递到shell脚本

$1 $2 ..

But my problem is my shell script needs to accept arguments from the command line as well as the function inside the shell script .

但是我的问题是shell脚本需要接受命令行中的参数以及shell脚本中的函数。

find my shell script below

在下面找到我的shell脚本

#!/bin/bash

extractZipFiles(){
  sudo unzip  "$4" -d "$5"
  if [ "$?" -eq 0 ]
  then
    echo "==>> Files extracted"
    return 0
  else
    echo "==>> Files extraction failed"
    echo "$?"
  fi
}

coreExtraction(){
extractZipFiles some/location some/other/location
}

coreExtraction

echo "====> $1"
echo "====> $2"
echo "====> $3"
echo "====> $4"
echo "====> $5"

I execute my shell script by passing

我通过传递执行shell脚本

sudo sh test.sh firstargument secondargument thirdargument

2 个解决方案

You can forward the original arguments with:

你可以将最初的论点与以下内容一起提出:

...
coreExtraction () {
    extractZipFiles "$@" some/location some/other/location
}
coreExtraction "$@"
...

To access the original script arguments from inside the function, you have to save them before you call the function, for instance, in an array:

要从函数内部访问原始脚本参数，必须在调用函数(例如，在数组中)之前保存它们:

args=("$@")
some_function some_other_args

Inside some_function, the script args will be in ${args[0]}, ${args[1]}, and so on. Their number will be ${#a[@]}.

在some_function中，脚本args将使用${args[0]}、${args[1]}等等。他们的号码是${#a[@]}。

Just pass the arguments from the command line invocation to the function

只需将参数从命令行调用传递到函数

coreExtraction "$1" "$2" "$3"
# or
coreExtraction "$@"

and add the other arguments to them

然后加上其他的参数

extractZipFiles "$@" some/location some/other/location
