Comando #Windows equivalente ao cat (#Unix). (#cmd #PowerShell #cat #linux #dev)

Posted on by

Se você está neste post, então (certamente) sabe que o comando cat exibe o conteúdo de um arquivo no terminal. Aqui eu mostro duas alternativas (uma para o prompt e outra para o PoweShell) que funcionam da mesma forma, só que no Windows.

Para todos os exemplos, considere um arquivo texto chamado lorem.txt e com o conteúdo:

Pork loin tri-tip meatloaf short loin turducken pork chop tail chislic jerky shoulder capicola. Kevin beef leberkas, brisket short loin frankfurter filet mignon ball tip fatback. Biltong hamburger tenderloin ham hock, boudin swine pork jerky porchetta ham ball tip picanha sirloin shoulder. Beef brisket jowl biltong turkey doner rump shankle chicken landjaeger.

Bacon ipsum dolor amet shoulder pastrami beef ribs, flank meatball t-bone spare ribs ham hock landjaeger turkey shank bresaola. Chicken cupim burgdoggen, kevin beef shankle kielbasa fatback ribeye short ribs doner cow t-bone. Andouille jowl pork belly shoulder, rump jerky chislic chicken pig biltong doner filet mignon pork turducken prosciutto. Meatloaf beef ribs sausage spare ribs cupim, shankle ham bacon picanha. Turducken ball tip ham hock swine, short ribs buffalo pork belly. Cupim sausage tri-tip strip steak tenderloin picanha short loin ball tip bresaola capicola shankle meatball ribeye turducken pork chop.
--EOF

Cmd (DOS) e Powershell

type lorem.txt

O resultado ficaria assim:

C:\temp> type lorem.txt

Turducken ball tip ham hock swine, short ribs buffalo pork belly. Cupim sausage tri-tip strip steak tenderloin picanha short loin ball tip bresaola capicola shankle meatball ribeye turducken pork chop.
--EOF

PowerShell

Get-Content lorem.txt

O resultado seria o mesmo:

PS C:\temp> Get-Content lorem.txt

Biltong hamburger tenderloin ham hock, boudin swine pork jerky porchetta ham ball tip picanha sirloin shoulder. Beef brisket jowl biltong turkey doner rump shankle chicken landjaeger.

Bacon ipsum dolor amet shoulder pastrami beef ribs, flank meatball t-bone spare ribs ham hock landjaeger turkey shank bresaola. Chicken cupim burgdoggen, kevin beef shankle kielbasa fatback ribeye short ribs doner cow t-bone. Andouille jowl pork belly shoulder, rump jerky chislic chicken pig biltong doner filet mignon pork turducken prosciutto. Meatloaf beef ribs sausage spare ribs cupim, shankle ham bacon picanha. Turducken ball tip ham hock swine, short ribs buffalo pork belly. Cupim sausage tri-tip strip steak tenderloin picanha short loin ball tip bresaola capicola shankle meatball ribeye turducken pork chop.
--EOF

Extra: Ordenando as linhas de um arquivo texto

SORT < lorem.txt

O resultado ficaria assim:

C:\temp> SORT < lorem.txt

--EOF

Se você comparar com o arquivo que mostrei inicialmente, vai ver que as linhas estão em ordem alfabética, sendo que o espaço entre as linhas veio primeiro e depois o indicador de final do arquivo (–EOF).

Extra 2: Criando arquivos texto no prompt de comando

type con > lorem2.txt

Depois de usar o comando acima, tudo que você digitar vai ser jogado para um novo arquivo chamado lorem2.txt.

Para encerrar a edição do arquivo, aperte Ctrl+Z. (Não sei o quão util é esta dica, mas é sempre bom saber…)

Espero ter ajudado!
