tr command - how to replace the string "\n" with an actual newline (\n)
提问by Alastair
I would like to use the trcommand to replace all occurrences of the string "\n" with a new line (\n).
我想使用该tr命令用新行 (\n) 替换所有出现的字符串“\n”。
I tried tr '\\n' '\n'but this just seems to match any '\' and any 'n'
我试过了，tr '\\n' '\n'但这似乎与任何 '\' 和任何 'n' 匹配
