bash - 来自 AppleScript 的 sed 命令插入 (i)

Question

我该怎么做呢：

# Insert a line "heater:M21789" before the line beginning with "fan"
$ sed '
/^fan/ i\
heater:M21789
' order789.txt

在 AppleScript 中？

Answer 1

删除了示例的 txt 文件：

set theInput to "title:
PO for vessel unit1 const.
items:
fan:F34539
tube:L1245
driller:M4545
Description:
PO signed and verified by factory manager S K Lp
Date: Fri Jan 2 17:26:44 UTC 2009
Author: M Kumar"


set xxx to do shell script "echo " & quoted form of theInput & " | sed '
/^fan/ i\\
heater:M21789
'"

return xxx

或严格遵守您的示例，对于 ~/ 中的文件 order789.txt

do shell script " cd ~; 
sed '
/^fan/ i\\
heater:M21789
' order789.txt"
