SebMa's questions

Criei a seguinte função no meu arquivo de script $PROFILE:

function host($name, $server, $type) {
    $FUNCNAME = $MyInvocation.MyCommand.Name
    $argc = $args.Count
    if ( $argc -eq 0 ) {
        "=> Usage : $FUNCNAME `$name [`$server] [`$type=A]"
    } elseif ( $argc -eq 1 ) {
        $fqdn = $name -Replace('https?://|s?ftps?://','') -Replace('/.*$','')
        (Resolve-DnsName $fqdn)[0].Name
        (Resolve-DnsName $fqdn).IP4Address
    } elseif ( $argc -eq 2 ) {
        $fqdn = $name -Replace('https?://|s?ftps?://','') -Replace('/.*$','')
        (Resolve-DnsName -name $fqdn -server $server)[0].Name
        (Resolve-DnsName -name $fqdn -server $server).IP4Address
    } elseif ( $argc -eq 3 ) {
        $fqdn = $name -Replace('https?://|s?ftps?://','') -Replace('/.*$','')
        if ( $type -eq "-4" ) {
            $type = "A"
        } elseif ( $type -eq "-6" ) {
            $type = "AAAA"
        } else {
            $type = "A_AAAA"
        }
        (Resolve-DnsName -type $type -name $fqdn -server $server)[0].Name
        (Resolve-DnsName -type $type -name $fqdn -server $server).IP4Address
    } else {
        Write-Warning "=> Not supported for the moment."
    }
}

Tentei buscar o valor do argcequivalente em C.

Então eu tentei $args.Count, mas ele sempre retorna 0de dentro da minha função.

Pode me ajudar ?

Tenho o seguinte /etc/docker/daemon.jsonarquivo:

$ yq . /etc/docker/daemon.json
{
  "dns": [
    "a.b.c.d1"
  ]
}
$

Tentei este comando para anexar linhas de proxy a este arquivo com yq:

$ yq '. + { proxies : {  "http-proxy":env($http_proxy) , "https-proxy":env($https_proxy) , "no-proxy":env($no_proxy)} }' /etc/docker/daemon.json
Error: 1:7: invalid input text "proxies : {  \"ht..."
$

Eu também tentei este yqcomando:

$ yq '. + { .proxies = {  .http-proxy=env($http_proxy) , .https-proxy=env($https_proxy) , .no-proxy=env($no_proxy)} }' /etc/docker/daemon.json
Error: !!str () cannot be added to a !!map ()
$

Espero este json:

{
  "dns": [
    "a.b.c.d1"
  ],
  "proxies": {
    "http-proxy": "http://x.y.z.t:8080",
    "https-proxy": "http://x.y.z.t:8080",
    "no-proxy": "localhost,127.0.0.1,localaddress,.localdomain.com"
  }
}

Como posso fazer isso com yq?

Quero testar se existe um alias com o seguinte código:

if( (get-alias ls) ) {
    echo "=> Alias ls already exists."
} else {
    echo "=> Alias ls does not exist."
}

Quando executado, ele diz:

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           ls -> Get-ChildItem


=> Alias ls already exits.

Tentei redirecionar a saída do comando para $null :

if( (get-alias ls >$null) ) {
    echo "=> Alias ls already exits."
} else {
    echo "=> Alias ls does not exist."
}

Eu esperava esta saída quando executado:

=> Alias ls already exists.

Mas o resultado do trecho de código mudou de alguma forma:

=> Alias ls does not exist.

Se eu redirecionar após o primeiro conjunto de parênteses, também obtenho:

=> Alias ls does not exist.

Por que o redirecionamento interfere no resultado?

Tenho os seguintes dados JSON:

Tentei esse comando cat toto.js | jq '[.][-1]', mas ele retorna o arquivo inteiro.

Estou tentando escrever uma função de alias do git com aspas simples para renomear e confirmar arquivos que podem ter espaços em seus nomes, mas não funciona:

$ grep '^\s*mvv' ~/.gitconfig 
    mvv = '!f() { cd ${GIT_PREFIX:-.};git mv -v "$1" "$2";git commit -uno "$1" "$2" -m "Renamed $1 to $2"; }; f'
$ git mvv "9.1.3 Packet Tracer - Identify MAC and IP Addresses - ILM.pdf" 9.1.3_Packet_Tracer_-_Identify_MAC_and_IP_Addresses_-_ILM.pdf
fatal: bad alias.mvv string: unclosed quote
$ git config alias.mvv
'!f() { cd ${GIT_PREFIX:-.}

Eu também tentei isso:

$ grep '^\s*mvv' ~/.gitconfig 
    mvv = !sh -c '{ cd ${GIT_PREFIX:-.};git mv -v "$1" "$2";git commit -uno "$1" "$2" -m "Renamed $1 to $2"; }'
$ git mvv "9.1.3 Packet Tracer - Identify MAC and IP Addresses - ILM.pdf" 9.1.3_Packet_Tracer_-_Identify_MAC_and_IP_Addresses_-_ILM.pdf
sh -c '{ cd ${GIT_PREFIX:-.}: 1: Syntax error: Unterminated quoted string
$ git config alias.mvv
!sh -c '{ cd ${GIT_PREFIX:-.}
$

Mas quando eu executo, aparece fatal: bad alias.mvv string: unclosed quoteerro.

Espero que funcione.
