An installed package may be upgraded with the version in file, with verbose output.

An installed package may be upgraded with the version in file, with verbose output and hash marks indicating progress.

An error will occur because a major mode is not specified

An error will occur because no file options were specified.

A single source package can be used on multiple CPU architectures.

By recompiling a source package, you can sometimes work around library incompat-
ibilities.

You can modify the code in a source package, thus altering the behavior of a program.

Source packages can be installed more quickly than binary packages.

You may be able to recompile source code for a non-Linux Unix program on Linux.

It’s generally inadvisable because the two systems don’t share installed-file database
information.

It’s impossible because their installed-file databases conflict with one another.

It causes no problems if you install important libraries once in each format.

It’s a common practice on Red Hat and Debian systems.

Using both systems simultaneously requires installing the alien program.

License requirements forbid using the package on any other distribution.

They may be used in another RPM-based distribution only when you set the
-- convert-distrib parameter to rpm.

They may be used in another RPM-based distribution only after you recompile the
package’s source RPM

They can be recompiled for an RPM-based distribution running on another type of
CPU.

They can often be used on another RPM-based distribution for the same CPU
architecture, but this isn’t guaranteed.

If the megaprog package is installed on the computer, it is uninstalled.

If the megaprog.rpm package exists, is valid, and isn’t already installed on the
computer, it is installed.

The megaprog.rpm source RPM package is compiled into a binary RPM for the
computer.

Nothing; megaprog.rpm isn’t a valid RPM filename, so rpm will refuse to operate on
this file.

The megaprog.rpm package replaces any earlier version of the package that’s already
installed on the computer.

Edit the /etc/apt/sources.list file to include the repository site’s URL, as detailed
on the repository’s website.

Download a package from the repository site, and install it with RPM, or place a
configuration file from the repository site in the /etc/yum.repos.d directory.

Use the add-repository subcommand to yum or the Add Repository option in the File
menu in yumex, passing it the URL of the repository.

Edit the /etc/yum.conf file, locate the [repos] section, and add the URL to the
repository after the existing repository URLs.

Edit the /etc/yum.conf file, locate the REPOSITORIES= line, and add the new
repository to the colon-delimited list on that line.

Modify the LD_LIBRARY_PATH environment variable in a global shell script.

Add the directory to the /etc/ld.so.conf file, and then type ldconfig.

Type ldconfig /new/dir, where /new/dir is the directory you want to add.

Create a symbolic link from that directory to one that’s already on the library path.

Type ldd /new/dir, where /new/dir is the directory you want to add.
