The split command first appeared in Version 3 Unix [1] and is part of the X/Open Portability Guide since issue 2 of 1987. It was inherited into the first version of POSIX.1 and the Single Unix Specification. [2] The version of split bundled in GNU coreutils was written by Torbjorn Granlund and Richard Stallman. [3]
The csplit command in Unix and Unix-like operating systems is a utility that is used to split a file into two or more smaller files determined by context lines. History [ edit ]
A script session is captured in file name typescript by default; to specify a different filename follow the script command with a space and the filename as such: script recorded_session. The recorded format of script consists of plain-text timing information (for the whole session) and verbatim command output, including whatever ANSI escape ...
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data.Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
Comma-separated values is a data format that predates personal computers by more than a decade: the IBM Fortran (level H extended) compiler under OS/360 supported CSV in 1972. [14] List-directed ("free form") input/output was defined in FORTRAN 77, approved in 1978. List-directed input used commas or spaces for delimiters, so unquoted character ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
Command arguments are split in different ways across platforms. Some systems do not split up the arguments; for example, when running the script with the first line, #!/usr/bin/env python3 -c all text after the first space is treated as a single argument, that is, python3 -c will be passed as one argument to /usr/bin/env, rather than two arguments.
R is a programming language for statistical computing and data visualization.It has been adopted in the fields of data mining, bioinformatics and data analysis. [9]The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data.
