64
65Sign all FILES, and process them at the destinations specified with --to.
66If CMD is not given, it defaults to uploading. See examples below.
67
68Commands:
69 --delete delete FILES from destination
70 --symlink create symbolic links
71 --rmsymlink remove symbolic links
72 -- treat the remaining arguments as files to upload
73
74Options:
75 --to DEST specify a destination DEST for FILES
76 (multiple --to options are allowed)
77 --user NAME sign with key NAME
78 --replace allow replacements of existing files
79 --symlink-regex[=EXPR] use sed script EXPR to compute symbolic link names
80 -n, --dry-run do nothing, show what would have been done
81 (including the constructed directive file)
82 --version output version information and exit
83 -h, --help print this help text and exit
84
85If --symlink-regex is given without EXPR, then the link target name
86is created by replacing the version information with '-latest', e.g.:
87 foo-1.3.4.tar.gz -> foo-latest.tar.gz
88
89Recognized destinations are:
90 alpha.gnu.org:DIRECTORY
91 savannah.gnu.org:DIRECTORY
92 savannah.nongnu.org:DIRECTORY
93 ftp.gnu.org:DIRECTORY
94 build directive files and upload files by FTP
95 download.gnu.org.ua:{alpha|ftp}/DIRECTORY
96 build directive files and upload files by SFTP
97 [user@]host:DIRECTORY upload files with scp
98
99Options and commands are applied in order. If the file $conffile exists
100in the current working directory, its contents are prepended to the
101actual command line options. Use this to keep your defaults. Comments
102(#) and empty lines in $conffile are allowed.
103
104<https://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
105gives some further background.
106
107Examples:
1081. Upload foobar-1.0.tar.gz to ftp.gnu.org:
109 gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
110
1112. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
112 gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
113
1143. Same as above, and also create symbolic links to foobar-latest.tar.*:
115 gnupload --to ftp.gnu.org:foobar \\
116 --symlink-regex \\
117 foobar-1.0.tar.gz foobar-1.0.tar.xz
118
1194. Create a symbolic link foobar-latest.tar.gz -> foobar-1.0.tar.gz
120 and likewise for the corresponding .sig file:
121 gnupload --to ftp.gnu.org:foobar \\
122 --symlink foobar-1.0.tar.gz foobar-latest.tar.gz \\
123 foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
124 or (equivalent):
125 gnupload --to ftp.gnu.org:foobar \\
126 --symlink foobar-1.0.tar.gz foobar-latest.tar.gz \\
127 --symlink foobar-1.0.tar.gz.sig foobar-latest.tar.gz.sig
128
1295. Upload foobar-0.9.90.tar.gz to two sites:
130 gnupload --to alpha.gnu.org:foobar \\
131 --to sources.redhat.com:~ftp/pub/foobar \\
132 foobar-0.9.90.tar.gz
133
1346. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
135 (the -- terminates the list of files to delete):
136 gnupload --to alpha.gnu.org:foobar \\
137 --to sources.redhat.com:~ftp/pub/foobar \\
138 --delete oopsbar-0.9.91.tar.gz \\
139 -- foobar-0.9.91.tar.gz
140
141gnupload executes a program ncftpput to do the transfers; if you don't
142happen to have an ncftp package installed, the ncftpput-ftp script in
143the build-aux/ directory of the gnulib package
144(https://savannah.gnu.org/projects/gnulib) may serve as a replacement.
