if:tldr:f5f92

This command is meant to evaluate a condition and perform an action if the condition is true.

Here's a breakdown of the command:

• if: This keyword marks the beginning of the conditional statement.
• ${condition_command}: This is where the condition is evaluated. condition_command can be any valid command or expression that results in a boolean (true/false) value. Typically, this would be something like checking if a variable is set, comparing two values, or executing a test command.
• then: This keyword marks the beginning of the action block, which contains the code to be executed if the condition is true.
• ${echo "Condition is true"}: This is the action that will be performed if the condition evaluates to true. In this example, it's the echo command with a string as an argument.
• fi: This keyword marks the end of the conditional statement.

In summary, if the ${condition_command} evaluates to true, the code within the action block (in this case, echo "Condition is true") will be executed. Otherwise, it will be skipped.
