在shell脚本中获取输入

Question

I know to get an input with a shell script you can do

echo "text"
read $VAR

or to get it at runtime

#! /bin/sh

if [ "$1" ]
then
  #do stuff
else
  echo "No input"
fi

But what if I want to get the entire string after I run it, including spaces? I could use quotation marks, but is there any way around this, so I can do: ./script.sh This is a sentence

Answer 1

Use

#!/bin/sh

if [ $# -gt 0 ] ; then
    echo "$*"
else
    echo "No input"
fi

But first, think about what you're doing and just pass a single quoted parameter.

Answer 2

./script.sh "This is a sentence"

另一种方法是

./script.sh This\ is\ a\ sentence
