Interrupted system call

Cause

The user issued an interrupt signal (usually Control-C) while the system was in the middle of executing a system call. When network service is slow, interrupting cd(1) to a remote-mounted directory can produce this message.

Action

Proceed with your work; this message is strictly informational.

Technical Notes

An asynchronous signal (such as interrupt or quit), which a program was set up to catch, occurred during an internal system call. If execution is resumed after processing the signal, it will appear as if the interrupted programming function returned this error condition, so the program might exit with an incorrect error message.

The symbolic name for this error is EINTR, errno=4.
