dput

dput(1) 						      General Commands Manual							   dput(1)

NAME

       dput - package upload tool for Debian

SYNTAX

       dput [options] [host] package.changes ...

DESCRIPTION

       This  is  a  tool  for uploading Debian packages into the archive. You may specify to which host it should upload the file by passing it an
       host argument. If omitted, dput uses the host specified by default_host (or, historically default_host_non-us) configuration option.   Also
       you have to pass the program one or more name of package.changes files and then they will be sequentially uploaded.

       This  program  will  then  upload  the  package for you into the archive, using a selected upload method. Currently dput supports ftp, scp,
       rsync, http, https, and local. The method scripts have been split from the main script  so  it  is  easy  to  add  new  methods.   Look	in
       /usr/share/dput/ for examples.

       Should  something  go  wrong  with your upload to destinations using the Debian upload queue daemon (e.g. ftp-master), you can remove files
       from the upload queue with dcut(1).

OPTIONS

       -c, --config - define a config file to use.

       -d, --debug - activate debugging mode, helpful if bugs occur.

       -D, --dinstall - do a dry run of dinstall after the upload.

       -f, --force - force an upload of an already uploaded package.

       -h, --help - print help information and exit.

       -H, --host-list - print the lists of hosts that dput knows about.

       -l, --lintian - run lintian before the upload.

       -U, --no-upload-log - do not write a .upload log file after uploading.

       -o, --check-only - check only the package and do not upload.

       -p, --print - print the configuration that dput is using.

       -P, --passive - use passive ftp instead of active. Note that passive ftp is the default unless specified  otherwise  in	the  configuration
       file.

       -s, --simulate - simulate an upload only.

       -u, --unchecked - don't check GnuPG signature on the changes file.

       -e,  --delayed  - Upload to a DELAYED queue, rather than the usual Incoming. This takes an argument from 0 to 15. Note that a delay of 0 is
       different from no delay at all.

       -v, --version - print version information and exit.

       -V, --check-version - check if the user has already installed and tested the package before putting it into the archive.
