bash用于解析三个大括号之间的所有字符串

Question

我有以下文字：

{{{VSER}}} is doing well. He went to {{{MARKET}}}.
It is very useful {{{RESOURCE}}}

我想解析{{{和}}}之间的字符串运行脚本echo $TEXT | somescript，然后结果应为：

VSER
MARKET
RESOURCE

尝试使用sed：

echo $TEXT | sed 's/.*{{{ //' | sed # /}}}.*$//'

但是，它会返回{{{VSER，甚至不返回VSER。

Answer 1

实测！

echo $TEXT | awk -vRS="}}}" -vFS="{{{" '{print $2}'

感谢您的时间

Answer 2

GNU grep有PCRE可用：

$ TEXT='{{{VSER     123}}} is doing well. He went to {{{MARKET}}}.
It is very useful {{{RESOURCE}}}'

$ echo $TEXT | grep -oP '\{\{\{\K.*?(?=}}})'
VSER 123
MARKET
RESOURCE

$ echo "$TEXT" | grep -oP '\{\{\{\K.*?(?=}}})'
VSER     123
MARKET
RESOURCE

$ # with perl
$ echo "$TEXT" | perl -lne 'print join "\n", /\{\{\{\K.*?(?=}}})/g'
VSER     123
MARKET
RESOURCE
