* commands: test: support signed comparisonsAhmad Fatoum2023-09-141-15/+51
| | | | | | | | | | | | | | | | | | | | | | | So far signed integers in binary comparisons were accepted, but compared unsigned resulting in [ "-1" -gt 0 ] returning true. Rework this, so that: - If one side is signed, the comparison is signed - If both sides are unsigned, the comparison is unsigned The latter is not required by POSIX, but it ensures that we don't break users who so far did comparisons with integers > LONG_MAX without issue. While at it, we start checking that the arguments in arithmetic comparisons are indeed integers. This has the result that e.g. [ "1x" -eq "1x" ] will no longer return success, but that aligns us with usual shell behavior and protects the users from silent truncation when a number > LONG_MAX is compared with a negative number.

* commands: test: add based support for bash-test styleMarco Felsch2023-07-281-6/+27
| | | | | | | | | | | | | Add bash-style test [[ expression ]] to support pattern matching like: - [[ "foo1" == "foo*" ]] - [[ "foo1" != "bar*" ]] For more information see man 1 bash.

* commands/*: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-04-271-16/+4
| | | | | | | | | | | | | 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/test: Improve option parsing to handle "]" less specialUwe Kleine-König2020-02-101-5/+8
| | | | | | | | | | | | Testing for *ap[1] != ']' is bogus during option processing. Instead test if there are options left to be processed.

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* 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 ...
