How do you run multiple programs in parallel from a bash script?
...ss terminates.
time xargs -P 3 -I {} sh -c 'eval "$1"' - {} <<'EOF'
sleep 1; echo 1
sleep 2; echo 2
sleep 3; echo 3
echo 4
EOF
The output looks something like:
1 # output from 1st command
4 # output from *last* command, which started as soon as the count dropped below 3

What's the difference between deadlock and livelock?
...When each learns they cannot continue they release their held resource and sleep for 30 seconds, then they retrieve their original resource followed by trying to the resource the other process held, then left, then reaquired. Since both processes are trying to cope (just badly), this is a livelock.

三、_access
当然C中还有一种方式是直接调用c的函数库。
就是函数 int _access(const char* path,int mode);
这个函数的功能十分强大。
