扑输出重定向到一个程序

问题描述

为什么不是阅读的文本文件。这里有什么更好的方式是我的code。
我试图使用读取一条线，但它似乎没有工作。

 如果[$＃-ne 1]
然后
    writeusage
    出口
科幻
your_path = .. /文件/ TEST1
test_path = .. / .. /公/ TEST1
file_input =$ 1
而读-r线
做
   ARGS + =$行
完成＆LT; $ file_input
＃输出重定向到一个文件名为text
$ test_path＆GT; correctanswer 2  - ;＆放大器; 1
＃您重定向输出到文件名为文本2
$ your_path＆GT; youranswer 2  - ;＆放大器; 1
＃差异的解决方案
差异correctanswer youranswer
 

解决方案

 （（$＃== 1））|| {writeusage; 1号出口; }your_path = .. /文件/ TEST1
test_path = .. / .. /公/ TEST1
file_input =$ 1＃对于bash比4.x的年长
而读-r线;做
   ARGS + =（$线）
完成＆LT; $ file_input## ...较新的bash中，你可以这样做，而不是：
＃readarray -t ARGS＆LT;$ file_input＃输出重定向到一个文件名为text
$ test_path$ {ARGS [@]}＆GT; correctanswer 2  - ;＆放大器; 1
＃您重定向输出到文件名为文本2
$ your_path$ {ARGS [@]}＆GT; youranswer 2  - ;＆放大器; 1
＃差异的解决方案

Why isn't it reading the text file. What's a better way here is my code.I am trying to read a line using for but it doesnt seem to work

if [[ "$#" -ne 1 ]]
then
    writeusage
    exit
fi
your_path=../file/test1
test_path=../../public/test1
file_input="$1"
while read -r line
do
   args+="$line"
done < "$file_input"
# Redirect the output to a file named text
$test_path > correctanswer 2>&1
# Redirect your output to a file named text2
$your_path > youranswer 2>&1
# diff the solutions
diff correctanswer youranswer

解决方案

(( $# == 1 )) || { writeusage; exit 1; }

your_path=../file/test1
test_path=../../public/test1
file_input="$1"

# for bash older than 4.x
while read -r line; do
   args+=( "$line" )
done < "$file_input"

## ...for newer bash, you could do this instead:
# readarray -t args <"$file_input"

# Redirect the output to a file named text
"$test_path" "${args[@]}" > correctanswer 2>&1
# Redirect your output to a file named text2
"$your_path" "${args[@]}" > youranswer 2>&1
# diff the solutions
diff correctanswer youranswer
