syntax of first case

+

if [ expresion 1 ]
+ then
+ statement to be executed if expresion 1 is true
+ elif [ expression 2 ]
+ then
+ statement to be executed if expresion 2 is true
+ elif [ expression 3 ]
+ then
+ statement to be executed if expresion 3 is true
+ else
+ statement to be executed if no expresion is true
+ fi
+

+
+

Explanation

+

On can use this command (expression) if we want select one of many blocks of code to execute.
+ It check one by one the expression and when is true it execute the statement and goes to next.
+ But if the expressions are false then it enters into else block and execute the else statement + +

+ +

Exemple

+

#!/bin/sh
+ var1=10
+ var2=10
+ if[ var1==1var2 ]
+ then
+ echo "var1 is equal var2"
+ elif [ $var1 -gt $var2 ]
+ then
+ echo "var1 is greater than var2"
+ elif [ $var1 -lt $var2 ]
+ then
+ echo "var1 is not equal var2"
+ else
+ echo "none of the condition is ok"
+ fi

syntax of For Loops

+

#!/bin/sh
+ for i in 1...N
+ do
+ Statement to be execudet for every word
+ done
+

+ +

Exemple

+ #!/bin/sh
+ for i in 1 2 3 4 5
+ echo "looping...number $1"
+ done
+ +

Explanation

+

The for loops iterate a throught a set of value, list of item until is finished.
+ Practicaly this loop repeat a set of commands for each item of the list

syntax of if-else

+

if [ expresion ]
+ then
+ statement to be executed if expresion is true
+ else
+ statement to be executed if expresion is false
+ fi
+

+
+

Explanation

+

This espression run if the conditional is true, than it execute the statement 1.
+ If the result of conditional expression is zero, it jump to "else part" and execute the statement 2. Finally after the execution of if/else, it resume with the consequent statement.

+ + +
+

Exemple

+

#!/bin/sh
+ var1=10
+ var2=10 + if[ var1==1var2 ]

+ echo "var1 is equal var2"
+ else
+ echo "var1 is not equal var2"

syntax of if

+

if [ expresion ]
+ then
+ statement to be executed if expresion is true
+ fi
+

+
+

Important notice

+
    +
  • if expression is a shell comand, then it will be
    + assumed true if it return 0 after execution
    • +
  • If it is a boolean expression, then it would be true
    + if it returns true
    • +
  • Space between braces and expression it's important because
    + no space produce a syntax error
    • +
  • "fi"is "if backward
    • +
+
+

Exemple

+

#!/bin/sh
+ var1=20
+ var2=10 + if[ var1==1var2 ]
+ then
+ echo "var1 is equal var2"

    If

    +

    We have tree forms of if Statement:

    + +
  • if-fi statement
    • +
  • if-else statement
    • +
  • if-elif else if
    • + +

    The "if" command it's most often invoked to test virtually every shell script

    In programming Languages Loops are important because this concept allows us
    + to repeat a task many times whitout repeat every time code

    syntax of While Loops

    +

    #!/bin/sh
    + while [ comand ]
    + do
    + statement to be exeuted if command is true
    + done
    +

    + +

    Exemple

    + #!/bin/sh
    + INPUT_STRING=hello
    + while [ "$INPUT_STRING"!="bye" ]
    + do
    + echo "please type something in (bye to quit)
    + read INPUT_STRING
    + echo "You typed: $INPUT_STRING"
    + done
    + +

    Explanation

    +

    In this exemple "echo" and read statement run will go forward until we type "bye"
    + Normaly "while" command execute a code if this expression code is true, and stop only when is false or when say (type) stop.
