Details
cmdline contains the Kernel or the process command line.
This is an "in-section" name collision covering 2 completely different files: - (this will be splitted one day)
Kernel
/proc/cmdline contains the arguments the Bootloader passes to the Kernel.
This is a printable space delimited single line string, which consists of keywords or assignments.
In FRITZ!OS it is passed to the Kernel by ADAM2 or EVA.
This file is used in many places in FRITZ!OS, see the kernel_args article.
Excerpt from the proc(5) man page:
/proc/cmdline
Arguments passed to the Linux kernel at boot time. Often
done via a boot manager such as lilo(8) or grub(8).
Process
/proc/<pid>/cmdline contains the arguments which are passed to the exe of a process.
This is an array of zero terminated strings or a zero size content.
Excerpt from the proc(5) man page:
/proc/[pid]/cmdline
This read-only file holds the complete command line for
the process, unless the process is a zombie. In the
latter case, there is nothing in this file: that is, a
read on this file will return 0 characters. The command-
line arguments appear in this file as a set of strings
separated by null bytes ('\0'), with a further null byte
after the last string.
If, after an execve(2), the process modifies its argv
strings, those changes will show up here. This is not the
same thing as modifying the argv array.
Furthermore, a process may change the memory location that
this file refers via prctl(2) operations such as
PR_SET_MM_ARG_START.
Think of this file as the command line that the process
wants you to see.
Examples
init, cat and ls are symlinks to busybox. The exe just knows the binary, cmdline knows the symlink.

Dependencies
Daily updated index of all dependencies of this object. Last update: GMT.
A ** in the Mod column marks info from Supportdata2 probes, which will always stay incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the Object occurs, not the Relation.

Model-Matrix
Daily updated index of the presence, path and size of this object for each model. Last update: 2024-04-20 04:33 GMT.
Showing all models using this object. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.

Help Supportdata2
The data in this article is incomplete since it was manually collected using the Supportdata2 project.
Unlike the Supportdata-Probes which have been collected for years Supportdata2 is brand new and only has a few probes.
If you have access to a shell then please help to extend the Supportdata2 collection to improve this data.
It's easy and it's done in minutes. Please send created data as an Email attachment to the address listed here. Thanks!
