我在谷歌上搜索了很多。我只想要这一行:
echo "Replace <newLine> it by <newLine> NEWLINE <newLine> in my OSX terminal <newLine> and bash script" | sed -e 's/<newLine>/\n/g'
在我的 osx 终端和我的 bash 脚本中工作。我不能用sed
这个吗?还有另一种单线解决方案吗?
这是使用 sed
echo "Replace <newLine> it by <newLine> NEWLINE <newLine> in my OSX terminal <newLine> and bash script" | sed 's/<newLine>/\'$'\n/g'
这是一篇解释原因的博文 - https://nlfiedler.github.io/2010/12/05/newlines-in-sed-on-mac.html
仅使用 bash:
STR="Replace <newLine> it by <newLine> NEWLINE <newLine> in my OSX terminal <newLine> and bash script"
$ echo ${STR//<newLine>/\\n}
Replace \n it by \n NEWLINE \n in my OSX terminal \n and bash script
$ echo -e ${STR//<newLine>/\\n}
Replace
it by
NEWLINE
in my OSX terminal
and bash script
这里有一个简单的解释 - 语法类似于 sed 的替换语法,但您使用双斜杠 ( //
) 来表示替换字符串的所有实例。否则,仅替换第一次出现的字符串。
这可能对您有用:
echo "Replace <newLine> it by <newLine> NEWLINE <newLine> in my OSX terminal <newLine> and bash script" |
sed 'G;:a;s/<newLine>\(.*\(.\)\)$/\2\1/;ta;s/.$//'
Replace
it by
NEWLINE
in my OSX terminal
and bash script
编辑:OSX 不接受多个命令,请参见此处
echo "Replace <newLine> it by <newLine> NEWLINE <newLine> in my OSX terminal <newLine> and bash script" |
sed -e 'G' -e ':a' -e 's/<newLine>\(.*\(.\)\)$/\2\1/' -e 'ta' -e 's/.$//'
Replace
it by
NEWLINE
in my OSX terminal
and bash script
还有一种方式:
echo "Replace <newLine> it by <newLine> NEWLINE <newLine> in my OSX terminal <newLine> and bash script" |
sed $'s|<newLine>|\\\n|g'
Replace
it by
NEWLINE
in my OSX terminal
and bash script
