O script de shell lança um erro não encontrado quando executado a partir de um arquivo sh. Mas se entrou manualmente os comandos funcionam

Question

Estou tentando usar o seguinte script para gerar um sitemap para o meu site. Quando executo como sh thsitemap.sh , recebo um erro como este e cria um arquivo sitemap.xml vazio:

thsitemap.sh: 22: thsitemap.sh: [[: not found
thsitemap.sh: 42: thsitemap.sh: [[: not found
thsitemap.sh: 50: thsitemap.sh: Syntax error: "(" unexpected

Mas como o mesmo usuário root quando eu manualmente copio e colo essas linhas no terminal, ele funciona sem nenhum erro e o arquivo sitemap.xml tem todos os URLs. Qual é o problema? Como posso consertar isso?

Answer 1

Execute o script como:

bash script.sh

ou apenas:

./script.sh

Quando bash é executado usando o nome sh , ele desabilita a maioria de suas extensões, como o operador [[ testing.

Como você tem a linha #!/bin/bash shebang, não é necessário especificar o interpretador de shell explicitamente na linha de comando. Executar o script como um comando usará essa linha para encontrar o shell.

    

Answer 2

Ambos os comandos ... if [[ debug = "...“ ]] ; then... estão incorretos, eles devem ler ...

if [ "debug" = "Y" -o "debug" = "y" ]
