The command-line SQL Plus interface continues in use, mostly [citation needed] for non-interactive scripting or for administrative purposes.

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] [5]
A command prompt (or just prompt) is a sequence of (one or more) characters used in a command-line interface to indicate readiness to accept commands. It literally prompts the user to take action. A prompt usually ends with one of the characters $ , % , # , [ 18 ] [ 19 ] : , > or - [ 20 ] and often includes other information, such as the path ...
In the DOS era, it was customary to add a PATH {program directory}; %PATH% or SET PATH = {program directory}; %PATH% line to AUTOEXEC.BAT. When a command is entered in a command shell or a system call is made by a program to execute a program, the system first searches the current working directory and then searches the path, examining each ...
The command is analogous to the Stratus OpenVOS change_current_dir command. [9] cd is frequently included built directly into a command-line interpreter. This is the case in most of the Unix shells (Bourne shell, tcsh, bash, etc.), cmd.exe on Microsoft Windows NT/2000+ and Windows PowerShell on Windows 7+ and COMMAND.COM on DOS/ Microsoft ...
This permission must be set for executable programs, in order to allow the operating system to run them. When set for a directory, the execute permission is interpreted as the search permission: it grants the ability to access file contents and meta-information if its name is known, but not list files inside the directory, unless read is set also.
For each corresponding line, paste will append the contents of each file at that line to its output along with a tab. When it has completed its operation for the last file, paste will output a newline character and move on to the next line. paste exits after all streams return end of file. The number of lines in the output stream will equal the ...
