在FreeBSD中，执行pkg升级时，报告的“候选人”数是什么意思？

Question

在FreeBSD系统上，当执行“pkg upgrade”时，会有一条消息指示候选者的数量。 pkg文档没有说明这些候选者是什么，或者列出它们的任何方式。

新系统上的输出示例......

pkg升级

Checking for upgrades (1 candidates): 100%
Processing candidates (1 candidates): 100%
Checking integrity... done (0 conflicting)
Your packages are up to date.

由于候选人在运行命令后仍然存在，因此它们不能表示可升级的包。什么是“候选人”？有没有办法列出候选人？

Answer 1

“候选人”相当于“可能受影响的包裹”。生活示例显示：

# pkg upgrade -n
Updating FreeBSD repository catalogue...
FreeBSD repository is up to date.
All repositories are up to date.
Checking for upgrades (251 candidates): 100%
Processing candidates (251 candidates): 100%
The following 250 package(s) will be affected (of 0 checked):
