Looping through Command Line Arguments

for ((c=1; c<=7; c++)) do echo "Welcome $c times" done

Batch Script – Return code
Return codes are the codes returned by programs when they are executed. If the command line is successful, it should return zero; if it is not successful, it should return non-zero. If the test fails, a non-zero value indicates the error number, and the user can attempt to resolve it by navigating to the error message.
The test may also return an exit code. A program’s or utility’s exit code usually appears when it finishes or terminates.
The list below includes some of the non-zero exit codes (with their respective errors) that programs may return
| Error Code | Description |

| 0 | Successful completion of the program. |

| 2 | An error indicating that the file could not be found in the specified location |
| 3 | An error message indicated that the specified path could not be found. |
| 5 | An indication that the user is not authorized to access the resource |
