【问题描述】：

在我的 ubuntu 机器中，突然运行了多个 git 进程。这会消耗大部分内存导致我的机器停止工作。

这些过程会随着时间的推移而不断增加。

我用以下命令杀死了进程作为临时解决方案，

$ pkill git

但无法弄清楚 git 作为进程运行的原因。

$ pstree -apl 命令给了我以下输出。

【解决方案1】：

在这种情况下，pstree 可以帮助您确定流程的开始位置：

pstree -apl

将列出所有正在运行的进程及其父进程（=启动它的进程）。这应该可以帮助您弄清楚是什么启动了所有这些 git 进程。

如果你已经弄清楚了，你可以看看如何阻止它们启动......

喜欢命令$ pstree -apl。问题在于我在.bashrc 中设置为默认终端（[[ $TERM != "screen" ]] && exec tmux -2）的tmux。从.bashrc 中删除它可以解决问题。会看的更远。感谢pstree。
