Is there a way to compare values in a tab separated txt file?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I have a .txt file with value that are tab separated like so with line breaks:



subject1:111    Ref[1442.1]    3.17e-10 [line-break]

subject1:111    Ref[1442.1]    2.17e-10 [line-break]

subject1:111    Ref[1442.1]    1.19e-10 [line-break]

subject1:123    Ref[1421.1]    5.17e-10 [line-break]

subject1:134    Ref[4215.1]    2.12e-10 [line-break]

subject1:134    Ref[4215.1]    8.10e-10 [line-break]

subject1:151    Ref[6531.1]    3.12e-10 [line-break]

subject1:151    Ref[6531.1]    6.17e-10 [line-break]


I want to parse all the first columns and if there are no other matches print the row, otherwise if they have matches, then take the smallest number that is in the 3rd column then print the whole row.



I've tried to play around with $1 and $3 but I can't figure out how to make it match all $1 in the file then compare all $3



For example the result would be 



subject1:111    Ref[1442.1]    1.19e-10 [line-break]

subject1:123    Ref[1421.1]    5.17e-10 [line-break]

subject1:134    Ref[4215.1]    2.12e-10 [line-break]

subject1:151    Ref[6531.1]    6.17e-10 [line-break]

          Monofisismo

          Image
          Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

          Olmecas

          Image
          Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
