Question

所以我在AppleScript中创建一个需要写入CSV列的脚本。我已经从CSV中读过，我有关于如何写入CSV的代码，但它根本不写。我想写第22列。目前，我可以从该列读取，但我不确定如何编辑列。或者有没有办法在像Excel这样的excel中编辑某个框来说“是”。我在下面附上了我的代码。

set theFile to (choose file)
set f to read theFile

-- break the file into paragraphs (c.f. rows)
repeat with row in (paragraphs of f)
    -- parse the row into comma-delimited fields
    set fields to parseCSV(row as text)
    -- now you have your data:
    set verifyAccountStatus to item 22 of fields
    set theResult to writeTo(verifyAccountStatus, "Yes", text, true)

end repeat

on parseCSV(theText)
    set {od, my text item delimiters} to {my text item delimiters, ","}
    set parsedText to text items of theText
    set my text item delimiters to od
    return parsedText
end parseCSV

on writeTo(targetFile, theData, dataType, apendData)
    -- targetFile is the path to the file you want to write
    -- theData is the data you want in the file.
    -- dataType is the data type of theData and it can be text, list, record etc.
    -- apendData is true to append theData to the end of the current contents of the file or false to overwrite it
    try
        set openFile to open for access file targetFile with write permission
        if apendData is false then set eof of openFile to 0
        write theData to openFile starting at eof as dataType
        close access openFile
        return true
    on error
        try
            close access file targetFile
        end try
        return false
    end try
end writeTo

编辑：出于某种原因，当我运行它时它不起作用。

set theFile to (choose file)
set openFile to open for access theFile with write permission
do shell script "awk -F, '$1 ~ /Line 7/{$22=\"hello\"} 1' openFile"
close access openFile

它说它无法打开文件openFile

也许考虑使用内置于OS X的awk来做这件事。假设您的文件名为file.csv，并且以逗号分隔，如下所示：

Line 0,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,16
Line 1,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,44
Line 2,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,93
Line 3,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,96
Line 4,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,19
Line 5,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,77
Line 6,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,30
Line 7,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,30
Line 8,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,1
Line 9,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,96

如果在终端中运行此awk脚本，它会将所有field22条目更改为“Hello”

awk -F, '{$22="hello"}1' OFS=, file.csv

并告诉你：

Line 0,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,16
Line 1,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,44
Line 2,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,93
Line 3,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,96
Line 4,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,19
Line 5,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,77
Line 6,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,30
Line 7,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,30
Line 8,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,1
Line 9,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,hello,f23,f24,96

如果您想在新文件中使用它，只需重定向输出，如下所示：

awk -F, '{$22="hello"}1' OFS=, file.csv > newfile.csv

您可以使用以下方式从Applescript中调用此方法：

do shell script "awk -F, '{$22=\"hello\"} 1' file.csv > newFile.csv"

如果您希望用户从对话框窗口中选择文件，那么您的文件名将位于Applescript变量中 - 在您的示例中，它名为theFile。然后，您需要将此转换为shell和awk理解的文件名，并引用它并将其传递给shell，如下所示：

do shell script "awk -F, '{$22=\"hello\"} 1'  & quoted form of POSIX path of theFile & " > /tmp/a"

如果您只想在包含“77”的行上更改字段22，请执行以下操作：

awk -F, '/77/ {$22="hello"} 1' file.csv

Line 0,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,16
Line 1,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,44
Line 2,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,93
Line 3,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,96
Line 4,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,19
Line 5 field2 field3 f4 f5 f6 f7 f8 f9 f10 f11 f12 f13 f14 f15 f16 f17 f18 f19 f20 f21 hello f23 f24 77
Line 6,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,30
Line 7,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,30

如果您只想在字段1与“第7行”匹配的行上更改field22，则可以执行以下操作：

awk -F, '$1 ~ /Line 7/ {$22="hello"} 1' file.csv
Line 0,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,16
Line 1,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,44
Line 2,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,93
Line 3,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,96
Line 4,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,19
Line 5,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,77
Line 6,field2,field3,f4,f5,f6,f7,f8,f9,f10,f11,f12,f13,f14,f15,f16,f17,f18,f19,f20,f21,f22,f23,f24,30
Line 7 field2 field3 f4 f5 f6 f7 f8 f9 f10 f11 f12 f13 f14 f15 f16 f17 f18 f19 f20 f21 hello f23 f24 30

注意：

-F,只是告诉awk输入字段用逗号分隔。 OFS=,告诉awk用逗号分隔输出字段。
