sed替换命令在Mac上不起作用 [英] sed replacement command not working on Mac

问题描述

我正在尝试使用sed用bash变量的值替换CMakelists.txt文件中的某些文本，但出现错误:

I'm trying to replace some text in a CMakelists.txt file with the value of a bash variable using sed, but I'm getting an error:

sed: 1: "'s/iPhone": invalid command code ?

sed命令:

sed -i "" 's/iPhone Developer/'$PROVPROF'/g' CMakelists.txt

PROVPROF始终具有以下格式的内容:

PROVPROF will always have something with this format:

iPhone Developer: Firstname Lastname (Numbers/Letters)

推荐答案

如果变量中的字符与用于s的定界符相同，请尝试使用另一个定界符:

If you have characters in your variable which are the same as the delimiter you used to s, try using another delimiter instead:

sed -i '' "s|iPhone Developer|$PROVPROF|g" CMakelists.txt

更罕见的事情:

sed -i '' $'s\xFFiPhone Developer\xFF'"$PROVPROF"$'\xFFg' CMakelists.txt

更新:

此外，请勿尝试将参数存储在变量中.分词并不总是能像您那样工作.这是错误的:

Update:

Also, don't try to store your arguments on a variable. Word splitting would not always work the way you do. This is wrong:

command="sed -i '' 's|iPhone Developer|$PROVPROF|g' CMakelists.txt"
$command

将出现类似sed: -e expression #1, char 1: unknown command: `''的错误消息.在其他sed上，消息可能有所不同.

Error message like sed: -e expression #1, char 1: unknown command: `'' would appear. On other seds the message may be different.

但是您可以使用数组:

command=(sed -i '' "s|iPhone Developer|$PROVPROF|g" CMakelists.txt)
"${command[@]}"

尽管如此，还是不​​值得赞扬的.如果可以直接运行，请直接运行.

It's still not commendable though. If you can run it directly, run it directly.
