Several open-source scripts have been developed to facilitate the construction of Python one-liners. Scripts such as pyp or Pyline import commonly used modules and provide more human-readable variables in an attempt to make Python functionality more accessible on the command line. Here is a redo of the above example (printing the last field of ...
Node.js programs are invoked by running the interpreter node interpreter with a given file, so the first two arguments will be node and the name of the JavaScript source file. It is often useful to extract the rest of the arguments by slicing a sub-array from process.argv .
One punched card usually represented one line of code. It was one discrete object that was easily counted. It was the visible output of the programmer, so it made sense to managers to count lines of code as a measurement of a programmer's productivity, even referring to such as "card images". Today, the most commonly used computer languages ...
In computing, move is a command in various command-line interpreters such as COMMAND.COM, cmd.exe, [1] 4DOS/4NT, and PowerShell. It is used to move one or more files or directories from one place to another. [2] The original file is deleted, and the new file may have the same or a different name.

For example, the diff command operates on two files at a time. The -n option to xargs specifies how many arguments at a time to supply to the given command. The command will be invoked repeatedly until all input is exhausted. Note that on the last invocation one might get fewer than the desired number of arguments if there is insufficient input.
In computing, tee is a command in command-line interpreters using standard streams which reads standard input and writes it to both standard output and one or more files, effectively duplicating its input. [1] It is primarily used in conjunction with pipes and filters. The command is named after the T-splitter used in plumbing. [2]
mv is a Unix command that moves one or more files or directories from one place to another. If both filenames are on the same filesystem, this results in a simple file rename; otherwise the file content is copied to the new location and the old file is removed.
