进程grep在等待输入(即I/O)时的状态称为阻塞,此时grep命令都无法运行 其实在两种情况下会导致一个进程在逻辑上不能运行, 1. 进程挂起是自身原因,遇到I/O阻塞,便要让出CPU让其他进程去执行,这样保证CPU一直在工作 2. 与进程无关,是操作系统层面,可能会因为一个进程占用时间过多,或者优先级等原因,而调用其他的...
env | grep SHELL or python3 -c 'import os;print(os.environ.get("SHELL","No shell defined"))' Since that variable is not commonly used on Windows, we're detecting the parent process from which pew has been invoked and use that as the user's preferred shell. IfCMDER_ROOTis defined ...

proto_path (or -I). You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think...
