  2. Bad command or file name - Wikipedia

    en.wikipedia.org/wiki/Bad_command_or_file_name

    "foo" is not recognized as an internal or external command, operable program or batch file. Some early Unix shells produced the equally cryptic " foo: no such file or directory " again accurately describing what is wrong but confusing users.

  3. pushd and popd - Wikipedia

    en.wikipedia.org/wiki/Pushd_and_popd

    If pushd is not provided with a path argument, in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories. The popd command removes (or 'pops', in the stack analogy) the current path entry from the stack and returns to the path at the top of the stack as the new working directory.

  4. Directory traversal attack - Wikipedia

    en.wikipedia.org/wiki/Directory_traversal_attack

    Unix /etc/passwd is a common file used to demonstrate directory traversal, as it is often used by crackers to try cracking the passwords. However, in more recent Unix systems, the /etc/passwd file does not contain the hashed passwords, and they are instead located in the /etc/shadow file, which cannot be read by unprivileged users on the machine.

  5. Exception handling - Wikipedia

    en.wikipedia.org/wiki/Exception_handling

    The first hardware exception handling was found in the UNIVAC I from 1951. Arithmetic overflow executed two instructions at address 0 which could transfer control or fix up the result. [16] Software exception handling developed in the 1960s and 1970s. Exception handling was subsequently widely adopted by many programming languages from the ...

  6. Entry point - Wikipedia

    en.wikipedia.org/wiki/Entry_point

    In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.

  7. Command-line interface - Wikipedia

    en.wikipedia.org/wiki/Command-line_interface

    Command-line interpreters allow users to issue various commands in a very efficient (and often terse) way. This requires the user to know the names of the commands and their parameters, and the syntax of the language that is interpreted. The Unix #! mechanism and OS/2 EXTPROC command facilitate the passing of batch files to external processors ...

  8. Cross-site request forgery - Wikipedia

    en.wikipedia.org/wiki/Cross-site_request_forgery

    The web server will not be able to identify the forgery because the request was made by a user that was logged in, and submitted all the requisite cookies. Cross-site request forgery is an example of a confused deputy attack against a web browser because the web browser is tricked into submitting a forged request by a less privileged attacker.

  9. Error recovery control - Wikipedia

    en.wikipedia.org/wiki/Error_recovery_control

    As the drive is not redundant, reporting segments as failed will only increase manual intervention. Without a hardware RAID controller or a software RAID implementation to drop the disk, normal (no TLER) recovery ability is most stable. In a software RAID configuration whether or not TLER is helpful is dependent on the operating system.
