Bash 中是没有原生的 Try Catch 语句的，但是今天从 https://www.xmodulo.com/catch-handle-errors-bash.html 上我看到了一种模拟 Try Catch 的方法。函数定义如下（经过了一些改造，更好理解一些，而且原文是有一点小错误的）：function try(){ if [[ $SHELLOPTS =
ERREXIT_P="Y" # 保存ERREXIT的启用情况 set +e # 若开启了ERREXIT则需要关闭该配置项,否则后面throw()返回非0值时会直接终止代码运行,也就没法运行后面的catch()语句了 fi } function throw() { exit $1 } function catch() { export exception_code=$? if [[ ${ERREXIT_P} == "Y" ]];then set...

The handler for (Bash) autocompletion exists with code 1 always, which is not helpful in case you want to catch errors, e.g. because some imports failed. Code reference:https://github.com/django/django/blob/bac13074ee5bf6b35e45370fc8b9b14448c765dd/django/core/management/__init__....
