cmdline-opts: category cleanup
Option cleanups:

 --get is not upload
 --form* are post
 - added several options into ldap, smtp, imap and pop3
 - shortened the category descriptions in the list

category curl fixes:

 --create-dirs removed from 'curl'
 --ftp-create-dirs removed from 'curl'
 --netrc moved to 'auth' from 'curl'
 --netrc-file moved to 'auth' from 'curl'
 --netrc-optional moved to 'auth' from 'curl'
 --no-buffer moved to 'output' from 'curl'
 --no-clobber removed from 'curl'
 --output removed from 'curl'
 --output-dir removed from 'curl'
 --remove-on-error removed from 'curl'

Add a "global" category:

- Made all "global" options set this category

Add a "deprecated" category:

- Moved the deprecated options to it (maybe they should not be in any
 category long term)

Add a 'timeout' category

- Put a number of appropriate options in it

Add an 'ldap' category

- Put the LDAP related option in there

Remove categories "ECH" and "ipfs"

- They should not be categories. Had only one single option each.

Remove category "misc"

- It should not be a category as it is impossible to know when to browse
  it.

--use-ascii moved to ftp and output
--xattr moved to output
--service-name moved to auth

Managen fixes:

- errors if an option is given a category name that is not already setup
  for in code

- verifies that options set `scope: global` also is put in category
  `global´

Closes #14101

SPDX-License-Identifier: curl Long: output Arg: Short: o Help: Write to file instead of stdout Category: important output Added: 4.0 Multi: per-URL See-also: - remote-name - remote-name-all - remote-header-name Example: - -o file $URL - "http://{one,two}.example.com" -o "file_#1.txt" - "http://{site,host}.host[1-5].example" -o "#1_#2" - -o file $URL -o file2 https://example.net

--output

Write output to the given file instead of stdout. If you are using globbing to fetch multiple documents, you should quote the URL and you can use # followed by a number in the filename. That variable is then replaced with the current string for the URL being fetched. Like in:

curl "http://{one,two}.example.com" -o "file_#1.txt"

or use several variables like:

curl "http://{site,host}.host[1-5].example" -o "#1_#2"

You may use this option as many times as the number of URLs you have. For example, if you specify two URLs on the same command line, you can use it like this:

curl -o aa example.com -o bb example.net

and the order of the -o options and the URLs does not matter, just that the first -o is for the first URL and so on, so the above command line can also be written as

curl example.com example.net -o aa -o bb

See also the --create-dirs option to create the local directories dynamically. Specifying the output as '-' (a single dash) passes the output to stdout.

To suppress response bodies, you can redirect output to /dev/null:

curl example.com -o /dev/null

Or for Windows:

curl example.com -o nul

Specify the filename as single minus to force the output to stdout, to override curl's internal binary output in terminal prevention:

curl https://example.com/jpeg -o -
