0ALIAS(1)																 0ALIAS(1)

NAME

       0alias -- create quick scripts to run 0launch

SYNOPSIS

       0alias ALIAS [INTERFACE [MAIN]]

DESCRIPTION

       Having  to keep typing the full URI for a program each time you want to run it with 0launch is annoying. 0alias will create a little script
       in your PATH to do it for you.

       Note: the newer "0install add" command provides a more efficient alternative to using aliases.

EXAMPLES

       A program can be invoked using 0launch:

       0launch http://rox.sourceforge.net/2005/interfaces/Edit

       To avoid having to keep entering the URI, create an alias:

       0alias rox-edit http://rox.sourceforge.net/2005/interfaces/Edit

       To run Edit now:

       rox-edit

       To select a different version, or check for updates:

       0alias rox-edit

       If an interface provides more than one program, you can specify which one to use instead of the default. e.g.

       0alias svn http://example.com/subversion

       0alias svnadmin http://example.com/subversion svnadmin

       (this is for older programs that use MAIN; for newer programs you may need to use --command instead)

COMMAND-LINE OPTIONS
       -c=COMMAND, --command=COMMAND
	      The generated script will execute COMMAND rather than the default ("run").

       -d=DIR, --dir=DIR
	      Install the script into directory DIR, rather than searching for a suitable directory in $PATH.

       -h, --help
	      Show the built-in help text.

       -m, --manpage
	      Display the manpage for the alias script given as the single argument. The alias can be an absolute  pathname,  or  the  name  of  a
	      script  in  $PATH.  If  the argument isn't an alias script, or if multiple arguments are given, then all arguments are passed to the
	      system 'man' command. This allows you to alias your man command like this:

	      alias man='0alias --manpage'

       -r, --resolve
	      Print the interface URI for the given alias script to stdout.

       -V, --version
	      Display version information.

NAME

       0store-secure-add -- add an implementation to the system cache

SYNOPSIS

       0store-secure-add DIGEST

DESCRIPTION

       This  command  imports  the  current  directory	into  the  system-wide	shared	Zero Install cache, as /var/cache/0install.net/implementa-
       tions/DIGEST.  This allows a program downloaded by one user to be shared with other users.

       The current directory must contain a file called '.manifest' listing all the files to be added (in the format required by DIGEST), and this
       file  must have the given digest. If not, the import is refused. Therefore, it is only possible to add a directory to the cache if its name
       matches its contents.

       It is intended that it be safe to grant untrusted users permission to call this command with elevated  privileges.  To  set  this  up,  see
       below.

SETTING UP SHARING

       To enable sharing, the system administrator should follow these steps:

       Create a new system user to own the cache:

       adduser --system zeroinst

       Create the shared directory, owned by this new user:

       mkdir /var/cache/0install.net

       chown zeroinst /var/cache/0install.net

       Use visudo(8) to add these lines to /etc/sudoers:

       Defaults>zeroinst env_reset,always_set_home

       ALL ALL=(zeroinst) NOPASSWD: /usr/bin/0store-secure-add

       Create a script called 0store-secure-add-helper in PATH to call it. This script must be executable and contain these two lines:

       #!/bin/sh

       exec sudo -S -u zeroinst /usr/bin/0store-secure-add "$@" < /dev/null

       The other Zero Install programs will call this helper script automatically.

FILES

       /var/cache/0install.net/implementations
	      System-wide Zero Install cache.

BUGS

       This program is EXPERIMENTAL. It has not been audited. Do not use it yet in security-critial environments.

       The env_reset line in sudoers may not be required. sudo(1) seems to do it automatically.

       If  sudo  let us check whether we could call a command then we could switch to using it automatically, instead of needing to add the helper
       script. Currently, sudo delays for one second and writes to auth.log if we try to use this system when it hasn't been set up.
