In its most basic use case, seq N prints out all the integers from 1 to N in sequence. This was convenient as the Unix shell at the time, the Bourne shell had no primitives for iterating over numbers, and its "for" command could only iterate over a list of words. seq was therefore used to generate such a list, as in this example:
In computing, Bash (short for "Bourne Again SHell,") [6] is an interactive command interpreter and command programming language [7] developed for UNIX-like operating systems.. Created in 1989 [8] by Brian Fox for the GNU Project, [9] it is supported by the Free Software Foundation [10] and designed as a 100% [11] free alternative for the Bourne shell (sh) [12] and other proprietary Unix sh
A screenshot of the original 1971 Unix reference page for glob – the owner is dmr, short for Dennis Ritchie.. glob() (/ ɡ l ɒ b /) is a libc function for globbing, which is the archetypal use of pattern matching against the names in a filesystem directory such that a name pattern is expanded into a list of names matching that pattern.
The first Unix shell was the Thompson shell, sh, written by Ken Thompson at Bell Labs and distributed with Versions 1 through 6 of Unix, from 1971 to 1975. [3] Though rudimentary by modern standards, it introduced many of the basic features common to all later Unix shells, including piping, simple control structures using if and goto , and ...
The types of objects that can be iterated across (my_list in the example) are based on classes that inherit from the library class ITERABLE. The iteration form of the Eiffel loop can also be used as a boolean expression when the keyword loop is replaced by either all (effecting universal quantification) or some (effecting existential ...
Mark Wahlberg is taking the term “beach body” to the next level.. In photos shared exclusively with PEOPLE, the actor, 53, was spotted showing off an ultra-muscular physique while vacationing ...
The shells bash, zsh and PowerShell offer this as a specific feature. [72] [73] Shells which do not offer this as a specific feature may still be able to turn off echoing through some other means. Shells executing on a Unix/Linux operating system can use the stty external command to switch off/on echoing of input characters. [74]
