While 循环不循环文件内容

While 循环不循环文件内容

我有一个功能

function abc{
 a=$1
 b=$2
 if [[ $a == $b ]]then;
  return 0
 else
  return 1
 fi
}

我正在 while 循环中使用该函数

 check="mystring"
 while IFS= read -r val; do
   echo "-----------------------${val}"
   if ! abc "${val}" "${check}"; then
     echo "${val} Failure " >> $OUTPUT_LOG_FILE
   else
     echo "${val} Success " >> $OUTPUT_LOG_FILE
   fi
 done <my_list.txt

我的list.txt内容如下：

somestring
otherstring
mystring

问题是它只是循环第一个变量而不循环其他变量。

您的脚本抛出了 7 个标记的错误shellcheck，因此这不是您正在运行的脚本。每个错误代码都有详细的描述，例如：github.com/koalaman/shellcheck/wiki/SC1095

另外，其中的所有扩展都abc应该被引用。

我不清楚abc给脚本增加了什么价值。内联编写测试甚至比调用函数还要短。

$ shellcheck -s bash -
function abc{
 a=$1
 b=$2
 if [[ $a == $b ]]then;
  return 0
 else
  return 1
 fi
}
check="mystring"
 while IFS= read -r val; do
   echo "-----------------------${val}"
   if ! abc "${val}" "${check}"; then
     echo "${val} Failure " >> $OUTPUT_LOG_FILE
   else
     echo "${val} Success " >> $OUTPUT_LOG_FILE
   fi
 done <my_list.txt
