AFAICT，continue在 for 循环中调用另一个函数会破坏errexit语义。在main()函数中，如果build()函数中有任何失败，我想继续进行下一次迭代：

#! /usr/bin/env bash

export PS4='# ${BASH_SOURCE}:${LINENO}: ${FUNCNAME[0]}() - [${SHLVL},${BASH_SUBSHELL},$?] '
set -o xtrace
set -o errexit

build() {
  local _foo=$1

  if [ "${_foo}" -eq 1 ]; then
    false
  fi

  printf "%s with foo=%s builds ok\\n" "${FUNCNAME[0]}" "${_foo}"
}

main() {
  for i in 1 2 3; do
    build $i || continue
  done
}

main "$@"

但是，continue在for循环内部会导致代码在函数内部继续build()运行，从而消除errexit标志的影响：

$ ./foo.sh 
# ./foo.sh:5: …

I want to connect to an EAP-TLS access point using iwd, however this fails because it apparently cannot open my client key:

# iwctl
[iwd]# station wlan0 connect foo
Not configured

iwd says:

My kernel is the latest stable one and I've enabled CONFIG_PKCS8_PRIVATE_KEY_PARSER:
