In linux For-loop and user variable shell scripting same or different ?

[@EngrAbhishekRoshan]

In Linux shell scripting, a for-loop and a user-defined variable are different concepts, although they can be used together within a script. Here's an explanation of each and how they can be related: For-loop A for-loop is a control flow statement for specifying iteration, which allows code to be executed repeatedly. Example of a For-loop #!/bin/bash for i in {1..5} do echo "Iteration $i" done This script will output: Iteration 1 Iteration 2 Iteration 3 Iteration 4 Iteration 5 User-defined Variable A user-defined variable is a variable that you create and assign a value to within your script. Example of a User-defined Variable #!/bin/bash name="Alice" echo "Hello, $name" This script will output: Hello, Alice Using For-loop with User-defined Variables You can use user-defined variables within a for-loop to perform operations on them or to control the loop's behavior. #!/bin/bash names=("Alice" "Bob" "Charlie") for name in "${names[@]}" do echo "Hello, $name" done This script will output: Hello, Alice Hello, Bob Hello, Charlie In summary, for-loops and user-defined variables are distinct but can be used together effectively in shell scripting. For-loops manage repetition, while variables store and manage data.

Sir $UID variable is working in terminal but not in script file.

[@EngrAbhishekRoshan]

1.Check Variable Scope: Ensure that the $UID variable is correctly defined and accessible in the script. Sometimes, variables available in the terminal might not be available in the script environment. 2.Echo the Variable: Add a line to your script to print the value of $UID to ensure it is being read correctly. echo "UID: $UID" 3.Define the Variable in the Script: UID=$(id -u) echo "UID: $UID" 4.Debugging the Script: Use set -x at the beginning of the script to enable debugging, which prints each command before executing it: #!/bin/bash set -x echo "UID: $UID"
