When should I use a FIFO instead of a standard pipe?

FIFOs (named pipes) are useful when you need asynchronous communication between unrelated processes or when you need a persistent communication channel that exists in the filesystem rather than a simple linear pipe.

How do coprocesses differ from standard background jobs?

Coprocesses create a bidirectional pipe between the shell and a command, allowing the shell to both write to the command's stdin and read from its stdout simultaneously using specific file descriptors.

Does this skill work with modern Bash versions?

Yes, it specifically includes patterns for Bash 4+ features like coproc and advanced file descriptor handling, while maintaining compatibility with standard POSIX streaming where applicable.

What is process substitution in Bash?

Process substitution allows you to treat the output of a command as a file (using (command)), enabling complex pipelines without temporary files.

개발자 도구

Implements advanced inter-process communication patterns in Bash using process substitution, named pipes, and efficient data streaming techniques.

소개

This skill empowers Claude to master complex Bash workflows by utilizing process substitution, FIFOs (named pipes), and coprocesses for efficient data handling without the need for temporary files. It provides production-ready implementation patterns for parallel data processing, bidirectional communication, real-time log aggregation, and sophisticated data pipelines. This is particularly useful for developers and DevOps engineers who need to build high-performance shell scripts that manage multiple data streams simultaneously while maintaining clean, robust code.
