* commands/*: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-04-271-16/+2
| | | | | | | | | | | | | While at it also drop references to the non-existing CREDITS file and do some small rearrangements for some uniform formatting. (SPDX-License-Identifier first, then copyright texts and then an empty line.) The advantage is that these specifiers are machine-parseable which helps license conformance.

* commands: mw: Use kstrto*() instead of simple_strtoul()Sascha Hauer2019-05-231-4/+20
| | | | | | | | Now that we have the kstrto*() functions we can use them to detect various errors in passing numbers on the command line. Start with the 'mw' command and make it more robust against illegal numbers. Signed-off-by: Sascha Hauer <>
* commands: teach commands that write to files to also create themUwe Kleine-König2018-08-101-1/+1
| | | | | | | | | | This allows to use the adapted commands on non-existing files which failed before with open: No such file or directory Signed-off-by: Uwe Kleine-König <> Signed-off-by: Sascha Hauer <>

* libfile: move open_and_lseek() to libfileSascha Hauer2016-04-151-0/+1
| | | | | | | libfile is a collection of helpers for handling files. open_and_lseek() is a perfect match for this, so move it there. Signed-off-by: Sascha Hauer <>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does probably too much, but it's hard (and very cumbersome/time consuming) to break it out. What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <> Signed-off-by: Sascha Hauer <>
* commands: group 'help' outputHolger Schurig2014-05-141-0/+1
| | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...

* memory commands: separate into one file per commandSascha Hauer2013-04-171-0/+104
Normally in commands we have one file per command which is named like the command itself. The memory commands are an exception to this. This patch changes this by separating the memory commands. This also has the effect that the memory commands can now be selected individually. Along the way we add some Kconfig help text for the commmands. Signed-off-by: Sascha Hauer <>
