的Bash shell脚本检查 [英] Bash shell script checker

问题描述

我必须写一个脚本，它可以获取其中包含9行和线9号（1-9）的文本文件。
例如：

I have to write a script, which gets a text file which contains 9 line and 9 number (1-9) in the lines. For example:

123456789

123456789

234567891

234567891

345678912

345678912

456789123

456789123

567891234

567891234

678912345

678912345

789123456

789123456

891234567

891234567

912345678

912345678

我要检查线路，并根据数独规则的行。
不能在一个行或行数相同。
所以这个例子是一个正确的解决方案。

I have to check lines and the rows based on the sudoku rules. Can't be same number in a line or in a row. So the example is a correct solution.

如何把它写在bash shell脚本？
我不能使用数组，所以我能做些什么？

How to write it in bash shell script? I cannot use arrays, so what can I do?

推荐答案

没有awk的一个解决方案，结合不同的其他工具。结果
编辑：此解决方案适用于数字之间的inputfile中称为输入和空格。请参阅有关更改此行为的意见。

A solution without awk, combining different other tools.
This solution works for an inputfile called input and spaces between the digits. See comments about changing this behaviour.

echo "Checking 9 lines"
if [ $(wc -l <input ) -ne 9 ]; then
        echo "Wrong number of lines"
        exit 1
fi
echo "Check for correct layout"
if [ $(grep -cv '^[1-9] [1-9] [1-9] [1-9] [1-9] [1-9] [1-9] [1-9] [1-9]$' input ) -ne 0 ]; then
   echo "Not all lines are correct, maybe spaces at the end of a line?"
   grep -v '^[1-9] [1-9] [1-9] [1-9] [1-9] [1-9] [1-9] [1-9] [1-9]$' input
   exit 1
fi
i=0
while read -r line; do
   ((i++))
   if [ $(echo "${line}" | tr " " "\n" | sort -u | wc -l ) -ne 9 ]; then
      echo "Wrong nr of unique numbers in row $i"
   fi
done <input
for j in {1..9}; do
   if [ $(cut -d" " -f${j} input | sort -u | wc -l ) -ne 9 ]; then
      echo "Wrong nr of unique numbers in column $j"
   fi
done
