A delimited text file is a text file used to store data, in which each line represents a single book, company, or other thing, and each line has fields separated by the delimiter. [3] Compared to the kind of flat file that uses spaces to force every field to the same width, a delimited file has the advantage of allowing field values of any length.
A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams. [1] [2] An example of a delimiter is the comma character, which acts as a field delimiter in a sequence of comma-separated values.
Delimiters frequently used include the comma, tab, space, and semicolon. Delimiter-separated files are often given a ".csv" extension even when the field separator is not a comma. Many applications or libraries that consume or produce CSV files have options to specify an alternative delimiter. [3]
In some cases, such as sed and Perl, alternative delimiters can be used to avoid collision with contents, and to avoid having to escape occurrences of the delimiter character in the contents. For example, in sed the command s,/,X, will replace a / with an X , using commas as delimiters.
Option -d specifies a single character delimiter (in the example above it is a colon) which serves as field separator. Option -f which specifies range of fields included in the output (here fields range from five till the end). Option -d presupposes usage of option -f. To output the third field of each line using space as the field delimiter:
When a node is split, one element moves to the parent, but one element is added. So, it must be possible to divide the maximum number U −1 of elements into two legal nodes. If this number is odd, then U =2 L and one of the new nodes contains ( U −2)/2 = L −1 elements, and hence is a legal node, and the other contains one more element, and ...
In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation.
newline terminated, separated by semicolon or comma (semicolon – result of receding statement hidden, comma – result displayed) MUMPS a.k.a. M newline terminates line-scope, the closest to a "statement" that M has, a space separates/terminates a command, allowing another command to follow
