Specify the maximum transfer rate you want curl to use - for both downloads
and uploads. This feature is useful if you have a limited pipe and you would like
your transfer not to use your entire bandwidth. To make it slower than it
otherwise would be.

The given speed is measured in bytes/second, unless a suffix is appended.
Appending 'k' or 'K' counts the number as kilobytes, 'm' or 'M' makes it
megabytes, while 'g' or 'G' makes it gigabytes. The suffixes (k, M, G, T, P)
are 1024 based. For example 1k is 1024. Examples: 200K, 3m and 1G.

The rate limiting logic works on averaging the transfer speed to no more than
the set threshold over a period of multiple seconds.

If you also use the --speed-limit option, that option takes precedence and
might cripple the rate-limiting slightly, to help keeping the speed-limit
logic working.
copyright: update all copyright lines and remove year ranges - they are mostly pointless in all major jurisdictions - many big corporations and projects already don't use them - saves us from pointless churn - git keeps history for us - the year range is kept in COPYING checksrc is updated to allow non-year using copyright statements Closes #10205 2023-01-02 20:51:48 +08:00			`c: Copyright (C) Daniel Stenberg, <daniel@haxx.se>, et al.`
docs/cmdline-opts: add copyright and license identifier to each file gen.pl now insists on C: and SPDX-License-Identifier: fields to be present in all files. Closes #9002 2022-06-14 06:12:03 +08:00			`SPDX-License-Identifier: curl`
cmdline-docs: more options converted over 2016-11-16 06:44:58 +08:00			`Long: limit-rate`

docs: add categories to all cmdline opts Adapted gen.pl with 'listcats' This commit is a part of "--help me if you can" Closes #5680 2020-07-13 20:15:04 +08:00			`Category: connection`
curl.1: provide examples for each option The file format for each option now features a "Example:" header that can provide one or more examples that get rendered appropriately in the output. All options MUST have at least one example or gen.pl complains at build-time. This fix also does a few other minor format and consistency cleanups. Closes #7654 2021-08-31 22:37:14 +08:00			`Example: --limit-rate 100K $URL`
			`Example: --limit-rate 1000 $URL`
			`Example: --limit-rate 10M $URL`
cmdline-opts: made the 'Added:' field mandatory Since "too old" versions are no longer included in the generated man page, this field is now mandatory so that it won't be forgotten and then not included in the documentation. Closes #7786 2021-09-28 17:50:07 +08:00			`Added: 7.10`

cmdline/docs: add a required 'multi' keyword for each option The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759 2022-10-18 16:39:43 +08:00			`Multi: single`
