pcopy

pcopy is a Unix command-line utility designed to copy files and directories recursively, preserving file attributes such as permissions, ownership, timestamps, and symbolic links. It is particularly useful for mirroring directory structures, backing up data, or transferring files between systems while maintaining their original properties.

The tool is part of the GNU Core Utilities package and is often used as an alternative to the standard `cp` command when more advanced copying features are required. Unlike `cp`, which does not handle symbolic links by default, pcopy follows them, ensuring that linked files are copied rather than the links themselves. It also supports dry-run mode, allowing users to preview operations before execution, which helps avoid accidental data loss.

pcopy operates in a manner similar to the `rsync` command but with a simpler interface, making it accessible for basic recursive copying tasks. It is commonly invoked with options such as `-r` for recursive copying, `-p` to preserve file attributes, and `-v` for verbose output. The tool is particularly useful in scripting environments where consistent file replication is necessary.

While pcopy is not as widely known as other Unix utilities, it remains a reliable choice for users who require precise control over file copying operations. Its inclusion in GNU Core Utilities ensures compatibility with most Unix-like systems, including Linux distributions. For more complex synchronization tasks, users may still prefer tools like `rsync` or specialized backup solutions.
