Unix 将文件路径变量插入Sed搜索/替换

我正在尝试用

sed

搜索/替换，以便在Ubuntu操作系统上将文件路径插入字符串

要搜索/替换的行的示例：

arc1.4x_os

blendpath="/home/weather/data/arc/"
sed "s/^arc1.4x_os/'\''open '${blendpath}'arc1.4x_os/g"

'open /home/weather/data/arc/arc1.4x_os

sed: -e expression #1, char 20: unknown option to `s'

尝试的Sed代码：

arc1.4x_os

blendpath="/home/weather/data/arc/"
sed "s/^arc1.4x_os/'\''open '${blendpath}'arc1.4x_os/g"

'open /home/weather/data/arc/arc1.4x_os

sed: -e expression #1, char 20: unknown option to `s'

预期输出：

arc1.4x_os

blendpath="/home/weather/data/arc/"
sed "s/^arc1.4x_os/'\''open '${blendpath}'arc1.4x_os/g"

'open /home/weather/data/arc/arc1.4x_os

sed: -e expression #1, char 20: unknown option to `s'

终端错误消息：

arc1.4x_os

blendpath="/home/weather/data/arc/"
sed "s/^arc1.4x_os/'\''open '${blendpath}'arc1.4x_os/g"

'open /home/weather/data/arc/arc1.4x_os

sed: -e expression #1, char 20: unknown option to `s'

下面的

sed

可能会对您有所帮助

echo "arc1.4x_os" | sed "s|arc1.4x_os|'open /home/weather/data/arc/&|"

我使用上面的

echo

来打印变量，例如，您也可以使用下面的

sed

来打印输入文件

sed "s|arc1.4x_os|'open /home/weather/data/arc/&|"  Input_file

我从来不知道可以使用管道分隔符，我一直使用正斜杠分隔符。
