This command is an example of a conditional statement written in a shell scripting language like Bash.
The structure of the command is as follows:
if
: keyword indicating the start of a conditional statement${condition}
: variable or expression that will be evaluated as a condition. If the condition is true, the subsequent command will be executed.(${echo Condition is true})
: the command to be executed if the condition is true. In this case, it is a simple command to print the message "Condition is true" to the console.
Here's how the command works:
- The
if
statement is used to check the condition specified within${condition}
. - If the condition is true, the command inside the parentheses
(${echo Condition is true})
will be executed. - The command
${echo Condition is true}
is composed of two parts:${}
is used to reference the value of a variable. In this case, it is used to reference the commandecho Condition is true
.echo
is a command used to display a message or value on the console.Condition is true
is the message that will be printed if the condition is true.
So, if the value or expression represented by ${condition}
evaluates to true, the message "Condition is true" will be printed to the console.
