bash: /bin/rm: Argument list too long
A glob like * expanded to more file names than the kernel allows in one command (ARG_MAX), so the command never ran.
fork: Cannot allocate memory / ENOMEM
The kernel refused a memory allocation — RAM and swap are exhausted, or overcommit/cgroup limits block it.
Text file busy (ETXTBSY) when replacing or running a binary
You tried to overwrite an executable that is currently running, or run one that is still open for writing.
C/C++: undefined reference to `pthread_create' — missing -pthread (also `dlopen`, `clock_gettime`)
