This will do it for you:<\/p>\n

^[\\w.]+=\\$\\d+(?:\\|[\\w.]+=\\$\\d+)*$\n<\/code><\/pre>\n
It matches at least one word character<\/em> or<\/strong> .<\/code> followed by an =<\/code>, $<\/code> and a digit. Then, optionally, a |<\/code> followed by the first sequence again. This optional<\/em> part can be repeated any number of times.<\/p>\n
See it here at regex101<\/a>.<\/p>\n
Edit<\/strong><\/p>\n
Allow multi-digit numbers.<\/p>\n
Edit 2<\/strong><\/p>\n
If you need to check the range being 0-12 use<\/p>\n
^[\\w.]+=\\$(?:\\d|1[012])(?:\\|[\\w.]+=\\$(?:\\d|1[012]))*$\n<\/code><\/pre>\n
Here’s an example<\/a>.<\/p>\n
Edit 3<\/strong><\/p>\n
As OP needed pure POSIX, here’s what we<\/em> ended up with:<\/p>\n
^[A-Za-z0-9_.]+=\\$(1[012]|[0-9])(\\|[A-Za-z0-9_.]+=\\$(1[012]|\u200c\u200b[0-9]))*$\n<\/code><\/pre>\n
No shorthand character classes nor non capturing groups.<\/p>\n<\/p><\/div>\n
