read_json_file.RdReads a JSON file and replaces path prefixes to handle differences between mounted drives across different operating systems or computing environments. This is particularly useful when working with shared files that are accessed through different mount points on different systems (e.g., server paths vs. locally mounted volumes).
read_json_file(file_path, sub1 = "/fh/working", sub2 = "/Volumes")Character; path to the JSON file to be read.
Character; the source path prefix to be replaced (default: "/fh/working"). This typically represents the server-side or remote path structure.
Character; the target path prefix to replace with (default: "/Volumes"). This typically represents the local mount point or path structure.
A parsed JSON object with all path strings modified to replace sub1 with sub2.
This function handles cross-platform path compatibility issues when JSON files contain absolute paths that need to be translated between different systems. For example, paths that refer to network drives or mounted filesystems might need different prefixes on server environments versus local workstations.
The function first checks if the specified file exists, then reads and parses the JSON content. It then recursively processes all string elements in the JSON structure, replacing the specified prefix with an alternative.

sub2 = "/Users/me/mounted/projects")
