Akụkụ mgbakọ na mwepụ nke Linux Shell Programming - Nkebi IV

Na post a, aga m atụle Scripts site na echiche mgbakọ na mwepụ na ọnụọgụ. Ọ bụ ezie na etinyere m edemede dị mgbagwoju anya (Mfe Calculator) na post gara aga, mana na akụkụ onye ọrụ ọ siri ike nghọta na ya mere m chere na m ga-eme ka ị mụta akụkụ ọzọ bara uru nke mmụta na obere ngwugwu.

Tupu edemede a, ebipụtara edemede atọ nke Shell Scripting Series ma ha bụ:

1. Ghọta Linux Shell na scripting Shell Basic – Nkebi nke Mbụ
2. 5 Edemede Shell iji mụta mmemme Shell – Nkebi nke Abụọ
3. Ịkwọ ụgbọ mmiri Site na Ụwa nke Linux BASH Scripting – Nkebi III

Ka anyị were ụfọdụ edemede na-atọ ụtọ bido usoro mmụta n'ihu, malite na scripts mgbakọ na mwepụ:

Edemede 1: Mgbakwunye

Mepụta faịlụ Adition.sh na chmod 755 na edemede dị ka akọwara na post gara aga wee mee ya.

#!/bin/bash
echo “Enter the First Number: ” 
read a 
echo “Enter the Second Number: ” 
read b 
x=$(expr "$a" + "$b") 
echo $a + $b = $x

 vi Additions.sh
 chmod 755 Additions.sh
 ./Additions.sh

“Enter the First Number: ” 
12 
“Enter the Second Number: ” 
13 
12 + 13 = 25

Edemede 2: Mbipụta

#!/bin/bash
echo “Enter the First Number: ” 
read a 
echo “Enter the Second Number: ” 
read b 
x=$(($a - $b)) 
echo $a - $b = $x

Rịba ama: N'ebe a, anyị dochiri expr ma kwe ka mgbakọ mgbakọ na mwepụ rụọ ọrụ na shei.

 vi Substraction.sh
 chmod 755 Substraction.sh
 ./Substraction.sh

13 
“Enter the Second Number: ” 
20 
13 - 20 = -7

Edemede 3: Mmụba

Ka ọ dị ugbu a, ị ga na-anụ ụtọ nke ukwuu, na-amụta scripts n'ụzọ dị mfe, yabụ nke na-esote n'usoro oge bụ Multiplication.

#!/bin/bash

Mara: Ee! N'ebe a, anyị etinyeghị uru nke ịba ụba na mgbanwe mana anyị mere ya ozugbo na nkwupụta mmepụta.

 vi Multiplication.sh

“Enter the First Number: ” 
11 
“Enter the Second Number: ” 
11 
11 * 11 = 121

Edemede 4: Nkewa

Right! Nke na-esote bụ Nkewa, ọzọkwa ọ bụ edemede dị mfe. Lelee ya n'onwe gị.

#!/bin/bash

12 / 3 = 4

Ederede 5: Tebụl

Ọ dị mma! Gịnị mgbe ndị a isi mgbakọ na mwepụ ọrụ. Ka anyị dee edemede na-ebipụta tebụl nọmba ọ bụla.
