如何将 sed 命令的输出作为变量？

如何将以下命令设为变量？我的意思是我需要将此命令分配给变量以便在 for 循环中使用它。

for i in $(sed 's|/home/bssuser/Scripts/Amany/log/bssuser/CDR/Postpaid_CDR_Log/||' /home/bssuser/Scripts/Amany/logs.csv )

我有一个文件名为 start，路径如下：

/home/bssuser/Scripts/Amany/log/bssuser/CDR/Postpaid_CDR_Log

我需要删除所有这些

答案1

var1="$(for i in $(sed 's|/home/bssuser/Scripts/Amany/log/bssuser/CDR/Postpaid_CDR_Log/||' /home/bssuser/Scripts/Amany/logs.csv ))"

对于 $(sed 's|/home/bssuser/Scripts/Amany/log/bssuser/CDR/Postpaid_CDR_Log/||' /home/bssuser/Scripts/Amany/logs.csv ) 中的 i

您的意思是循环读取每行输出到变量中吗？如果是这样，那么您可以使用Bash 的进程替换使用while如下循环：

while IFS= read -r line
  do
    # Do whatever you want with the line
    echo "$line"
    done < <(sed 's|/home/bssuser/Scripts/Amany/log/bssuser/CDR/Postpaid_CDR_Log/||' /home/bssuser/Scripts/Amany/logs.csv)

也可以通过将输出传送到循环来完成，如下所示：

sed 's|/home/bssuser/Scripts/Amany/log/bssuser/CDR/Postpaid_CDR_Log/||' /home/bssuser/Scripts/Amany/logs.csv |
while IFS= read -r line
  do
    # Do whatever you want with the line
    echo "$line"
    done
