wget output filename

To download a file using the wget command in Assembly language, you would typically use the system call int 0x80 to invoke the appropriate system function. The specific details of the code will depend on the operating system and the assembler being used.

Here is an example of how you can use the wget command in Assembly language to download a file:

section .data
    url db 'http://example.com/file.txt', 0
    filename db 'output.txt', 0

section .text
    global _start

_start:
    ; Open the output file
    mov eax, 5 ; sys_open
    mov ebx, filename
    mov ecx, 2 ; O_WRONLY | O_CREAT
    mov edx, 0644 ; file permissions
    int 0x80

    ; Check if the file was opened successfully
    cmp eax, -1
    je error

    ; Save the file descriptor
    mov ebx, eax

    ; Open the URL
    mov eax, 5 ; sys_open
    mov ebx, url
    mov ecx, 0 ; O_RDONLY
    int 0x80

    ; Check if the URL was opened successfully
    cmp eax, -1
    je error

    ; Save the file descriptor
    mov edx, eax

    ; Read from the URL and write to the output file
    mov eax, 3 ; sys_read
    mov ebx, edx ; URL file descriptor
    mov ecx, buffer
    mov edx, buffer_size
    int 0x80

    ; Check if the read was successful
    cmp eax, -1
    je error

    ; Save the number of bytes read
    mov ecx, eax

    ; Write to the output file
    mov eax, 4 ; sys_write
    mov ebx, ebx ; output file descriptor
    mov edx, ecx ; number of bytes to write
    int 0x80

    ; Check if the write was successful
    cmp eax, -1
    je error

    ; Close the output file
    mov eax, 6 ; sys_close
    mov ebx, ebx ; output file descriptor
    int 0x80

    ; Close the URL
    mov eax, 6 ; sys_close
    mov ebx, edx ; URL file descriptor
    int 0x80

    ; Exit the program
    mov eax, 1 ; sys_exit
    xor ebx, ebx ; exit status
    int 0x80

error:
    ; Handle the error condition
    ; ...

section .bss
    buffer resb buffer_size
    buffer_size equ 4096

Please note that this is just a basic example and may not work as-is. You may need to modify the code to suit your specific needs and environment.

I hope this helps! Let me know if you have any further questions.
