$Usage
|
|
For each filename given, $name uuencodes the file, using the final
|
|
component of the file's path as the stored filename in the uuencoded
|
|
archive and, with a .${SUF} appended, as the name to store the archive in.
|
|
Example:
|
|
$name /tmp/foo
|
|
The file /tmp/foo is uuencoded, with \"foo\" stored as the name to uudecode
|
|
the file into, and the output is stored in a file in the current directory
|
|
with the name \"foo.${SUF}\".
|
|
Options:
|
|
-f: Normally, if the file the output would be stored in already exists,
|
|
it is not overwritten and an error message is printed. If -f (force)
|
|
is given, it is silently overwritten.
|
|
-h: Print this help."
