More posts from the commandline community. While using a string variable, that variable should be inserted in double quotes. Ill dig through the various packages mentioned to see if any makes it worth upgrading from my simple but working shell script. #as the string are not same, it will return Output: #as the string is empty, it will return 0 Output:Ġ Example 2: To check if both strings are same #!/bin/bash Below are the options available on string test.Įcho $? #This will return the output of previous command. Below is the syntax and some options while using file test.īelow are the options available on test files: You can make the nest as deep as you want, though it will continue to grow in complexity. The if statements become more complex when you nest them together, or in other words put one if statement inside of another if statement. We shall learn about it more in later chapter. In simple terms, these conditional statements define if a condition is true, then do that, otherwise do this instead. “test” keyword is used to test simple condition is true or false.įile test is used on files in particular. Syntax: if įi Output: the value is greater than 9 5.6. There can be an if statement inside a if statement. If there is a need to execute set of statements if the condition is true, and another set of statements if the condition is false, in this scenario we use “if-else”. Example: I have created a shell script with below program: #!/bin/bash There should be a space between the braces and the condition. If there is no space, error will be produced. There should be a space between “if” and opening braces “[“. In if condition, the set of statements is executed if the condition is satisfied, else the statements will not be executed. Shell script will support below conditional statements:ĥ.5 case statement With the help of conditional statements, we are able to branch the execution of a program. In this situation we make use of conditional statements. While writing a program, there exists a situation where we need to execute a set of statements based on some conditions.
