Fdr is a file descriptor redirector; a utility that executes a specified command with various file descriptor redirections in place. The bash shell provides very flexible redirection facilities for command pipelines. In certain cases, however, this redirection is inapplicable without invoking a subshell (for example, separating the two stderr's from 'time cmd'). Fdr is a lightweight alternative to using a full bash interpreter for these cases.
Rbmhshow seeks to provide an efficient and lightweight MIME- capable command-line MH mail environment, leveraging existing applications wherever possible. It is a flexible alternative to the standard MH mhl and mhshow applications. MIME messages are displayed in a single continuous less session, with non-plaintext components (e.g. HTML, Word, JPEG) converted to text by the appropriate utility. PGP and S/ MIME signatures are automatically validated, headers and separators are coloured, and the less prompt displays information about the current mail. Command keys are then provided within less to perform common operations, such as replying to, refiling or deleting mail, moving to the next message, etc.
