FISH Protocol
Files transferred over Shell protocol (FISH) is a network protocol that uses Secure Shell (SSH) or Remote Shell (RSH) to transfer files between computers and manage remote files. The advantage of FISH is that all it requires on the server-side is an SSH or RSH implementation, Unix shell, and a set of standard Unix utilities (like ls, cat or dd—unlike other methods of remote access to files via a remote shell, scp for example, which requires ''scp'' on the server side). Optionally, there can be a special FISH server program (called ''start_fish_server'') on the server, which executes FISH commands instead of Unix shell and thus speeds up operations. The protocol was designed by Czech Linux Kernel Hacker, Pavel Machek, in 1998 for the Midnight Commander software tool. Protocol messages Client sends text requests of the following form: #FISH_COMMAND arguments... equivalent shell commands, which may be multi-line Fish commands are all defined, shell equivalents may vary. ...

Protocol (computing)
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are t ...

Midnight Commander
GNU Midnight Commander (also known as mc, the command used to start it, and as mouseless commander in older versions) is a free cross-platform orthodox file manager. It was started by Miguel de Icaza in 1994 as a clone of the then-popular Norton Commander. GNU Midnight Commander is part of the GNU project and is licensed under the terms of the GNU General Public License. Design Midnight Commander is a console application with a text user interface. The main interface consists of two panels which display the file system. File selection is done using arrow keys, the insert key is used to select files and the function keys perform operations such as renaming, editing and copying files. Later versions of the Midnight Commander additionally have mouse support. Such versions are aware of GPM and X terminal emulators (such as GNOME Terminal or xterm) which support mouse reporting. When running inside an X terminal, these versions can update the name of the window in which Midnigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SSHFS
In computing, SSHFS (SSH Filesystem) is a filesystem client to mount and interact with directories and files located on a remote server or workstation over a normal ssh connection. The client interacts with the remote file system via the SSH File Transfer Protocol (SFTP), a network protocol providing file access, file transfer, and file management functionality over any reliable data stream that was designed as an extension of the Secure Shell protocol (SSH) version 2.0. The current implementation of SSHFS using FUSE is a rewrite of an earlier version. The rewrite was done by Miklos Szeredi, who also wrote FUSE. Features SFTP provides secure file transfer from a remote file system. While SFTP clients can transfer files and directories, they cannot mount the server's file system into the local directory tree. Using SSHFS, a remote file system may be treated in the same way as other volumes (such as hard drives or removable media). Using the Unix command ls with sshfs ...

Emacs TRAMP
Emacs , originally named EMACS (an acronym for "Editor MACroS"), is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on its direct descendant, GNU Emacs, continues actively; the latest version is 28.2, released in September 2022. Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macros to automate work. Implementations of Emacs typically feature a dialect of the Lisp programming language, allowing users and developers to write new commands and applications for the editor. Extensions have been written to, among other things, manage files, remote access, e-mail, outlines, multimedia, git integration, and RSS feeds, as well as implementations of ''ELIZA'', ''Pong'', '' Conway's Life'', '' ...

Dolphin (file Manager)
Dolphin is a free and open source file manager included in the KDE Applications bundle. Dolphin became the default file manager of the KDE Plasma desktop environments in the fourth iteration, termed KDE Software Compilation 4. It can also be optionally installed on K Desktop Environment 3. It replaces Konqueror as the default file manager for KDE SC 4, but Konqueror can still be used as an alternative file manager. Under previous K Desktop Environment versions, Konqueror had served both as the default file manager and web browser. However, for many years users have been critical of Konqueror as being too complex for simple file navigation. As a response, the two functions were divided into two separate applications. Under KDE SC 4, Dolphin was streamlined for browsing files, while sharing as much code as possible with Konqueror. Konqueror continues to be developed primarily as a web browser. In 2014, work started on porting Dolphin to KDE Frameworks 5. This is now complete and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krusader
Krusader is an advanced orthodox file manager for KDE and other desktops in the Unix world. It is similar to the console-based GNU Midnight Commander, GNOME Commander for the GNOME desktop environment, or Total Commander for Windows, all of which can trace their paradigmatic features to the original Norton Commander for DOS. It supports extensive archive handling, mounted filesystem support, FTP, advanced search, viewer/editor, directory synchronisation, file content comparisons, batch renaming, etc. It supports the following archive formats: tar, ZIP, bzip2, gzip, RAR, ace, ARJ, LHA, 7z and RPM and can handle other KIO Slaves such as smb or fish. Krusader is published under GNU GPL-2.0-or-later. User interface Krusader's user interface is based on the orthodox file manager (OFM) principle, also known as Commander-like file managers, the family of file managers based on the old Norton Commander interface. The orthodox file manager has two windows called panels where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Konqueror
Konqueror is a free and open-source web browser and file manager that provides web access and file-viewer functionality for file systems (such as local files, files on a remote FTP server and files in a disk image). It forms a core part of the KDE Software Compilation. Developed by volunteers, Konqueror can run on most Unix-like operating systems. The KDE community licenses and distributes Konqueror under GNU GPL-2.0-or-later. The name "Konqueror" echoes a colonization paradigm to reference the two primary competitors at the time of the browser's first release: "first comes the Navigator, then Explorer, and then the Konqueror". It also follows the KDE naming convention: the names of most KDE programs begin with the letter K. Konqueror first appeared with version 2 of KDE on October 23, 2000. It replaces its predecessor, KFM (KDE file manager). With the release of KDE 4, Dolphin replaced Konqueror as the default KDE file manager, but the KDE community continues to maintain ...

Lftp
lftp is a command-line program client for several file transfer protocols. lftp is designed for Unix and Unix-like operating systems. It was developed by Alexander Lukyanov, and is distributed under the GNU General Public License. lftp can transfer files via FTP, FTPS, HTTP, HTTPS, FISH, SFTP, BitTorrent, and FTP over HTTP proxy. It also supports the File eXchange Protocol (FXP), which allows the client to transfer files from one remote FTP server to another. Among lftp's features are transfer queues, segmented file transfer, resuming partial downloads, bandwidth throttling, and recursive copying of file directories. The client can be used interactively or automated with scripts. It has Unix shell-like job control, and a facility for scheduling file transfers for execution at a later time. Development history lftp was initially developed as part of the ftpclass package. Subsequently it grew and became a more capable program (e.g., mirroring capability was added), and was ...

Secure Copy
Secure copy protocol (SCP) is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. "SCP" commonly refers to both the Secure Copy Protocol and the program itself. According to OpenSSH developers in April 2019, SCP is outdated, inflexible and not readily fixed; they recommend the use of more modern protocols like SFTP and rsync for file transfer. As of OpenSSH version 9.0, scp client therefore uses SFTP for file transfers by default instead of the legacy SCP/RCP protocol. Secure Copy Protocol The SCP is a network protocol, based on the BSD RCP protocol, which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit. A client can send (upload) files to a server, optionally including their basic attribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secure Shell
The Secure Shell Protocol (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution. SSH applications are based on a client–server architecture, connecting an SSH client instance with an SSH server. SSH operates as a layered protocol suite comprising three principal hierarchical components: the ''transport layer'' provides server authentication, confidentiality, and integrity; the ''user authentication protocol'' validates the user to the server; and the ''connection protocol'' multiplexes the encrypted tunnel into multiple logical communication channels. SSH was designed on Unix-like operating systems, as a replacement for Telnet and for unsecured remote Unix shell protocols, such as the Berkeley Remote Shell (rsh) and the related rlogin and rexec protocols, which all use insecure, plaintext transmission of authentication tokens. SSH was first de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dd (Unix)
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; can also read and/or write from/to these files, provided that function is implemented in their respective driver. As a result, can be used for tasks such as backing up the boot sector of a hard drive, and obtaining a fixed amount of random data. The program can also perform conversions on the data as it is copied, including byte order swapping and conversion to and from the ASCII and EBCDIC text encodings. History The name is an allusion to the DD statement found in IBM's Job Control Language (JCL), in which it is an abbreviation for "Data Definition". The command's syntax resembles a JCL statement more than other Unix commands do, so much th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat (Unix)
cat is a standard Unix utility that reads files sequentially, writing them to standard output. The name is derived from its function to (con)catenate files (from Latin ''catenare'', "to chain"). It has been ported to a number of operating systems. History cat was part of the early versions of Unix, e.g., Version 1, and replaced pr, a PDP-7 and Multics utility for copying a single file to the screen. It was written by Ken Thompson and Dennis Ritchie. The version of cat bundled in GNU coreutils was written by Torbjorn Granlund and Richard Stallman. The ReactOS version was written by David Welch, Semyon Novikov, and Hermès Bélusca. Over time, alternative utilities such as tac and bat also became available, bringing different new features. Usage The Single Unix Specification defines the operation of cat to read files in the sequence given in its arguments, writing their contents to the standard output in the same sequence. The specification mandates the support of one option fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
