The \fIuudecode\fP utility shall scan the input file, searching +for +data compatible with one of the formats specified in \fIuuencode\fP, +and attempt to +create or overwrite the file described by the data (or overridden +by the \fB-o\fP option). The pathname shall be contained in the +data or specified by the \fB-o\fP option. The file access permission +bits and contents for the file to be produced shall be +contained in that data. The mode bits of the created file (other than +standard output) shall be set from the file access permission +bits contained in the data; that is, other attributes of the mode, +including the file mode creation mask (see \fIumask\fP() ), shall +not affect the file being produced. +.LP +If the pathname of the file to be produced exists, and the user does +not have write permission on that file, \fIuudecode\fP +shall terminate with an error. If the pathname of the file to be produced +exists, and the user has write permission on that file, +the existing file shall be overwritten. +.LP +If the input data was produced by \fIuuencode\fP on a system with +a different number +of bits per byte than on the target system, the results of \fIuudecode\fP +are unspecified. +.SH OPTIONS +.LP +The \fIuudecode\fP utility shall conform to the Base Definitions volume +of IEEE\ Std\ 1003.1-2001, Section 12.2, Utility Syntax Guidelines. +.LP +The following option shall be supported by the implementation: +.TP 7 +\fB-o\ \fP \fIoutfile\fP +A pathname of a file that shall be used instead of any pathname contained +in the input data. Specifying an \fIoutfile\fP +option-argument of \fB/dev/stdout\fP shall indicate standard output. +.sp +.SH OPERANDS +.LP +The following operand shall be supported: +.TP 7 +\fIfile\fP +The pathname of a file containing the output of \fIuuencode\fP. +.sp +.SH STDIN +.LP +See the INPUT FILES section. +.SH INPUT FILES +.LP +The input files shall be files containing the output of \fIuuencode\fP. +.SH ENVIRONMENT VARIABLES +.LP +The following environment variables shall affect the execution of +\fIuudecode\fP: +.TP 7 +\fILANG\fP +Provide a default value for the internationalization variables that +are unset or null. (See the Base Definitions volume of +IEEE\ Std\ 1003.1-2001, Section 8.2, Internationalization Variables +for +the precedence of internationalization variables used to determine +the values of locale categories.) +.TP 7 +\fILC_ALL\fP +If set to a non-empty string value, override the values of all the +other internationalization variables. +.TP 7 +\fILC_CTYPE\fP +Determine the locale for the interpretation of sequences of bytes +of text data as characters (for example, single-byte as +opposed to multi-byte characters in arguments and input files). +.TP 7 +\fILC_MESSAGES\fP +Determine the locale that should be used to affect the format and +contents of diagnostic messages written to standard +error. +.TP 7 +\fINLSPATH\fP +Determine the location of message catalogs for the processing of \fILC_MESSAGES +\&.\fP +.sp +.SH ASYNCHRONOUS EVENTS +.LP +Default. +.SH STDOUT +.LP +If the file data header encoded by \fIuuencode\fP is \fB-\fP or \fB/dev/stdout\fP, +or the \fB-o\fP \fB/dev/stdout\fP option overrides the file data, +the standard output shall be in the same format as the file +originally encoded by \fIuuencode\fP. Otherwise, the standard output +shall not be +used. +.SH STDERR +.LP +The standard error shall be used only for diagnostic messages. +.SH OUTPUT FILES +.LP +The output file shall be in the same format as the file originally +encoded by \fIuuencode\fP. +.SH EXTENDED DESCRIPTION +.LP +None. +.SH EXIT STATUS +.LP +The following exit values shall be returned: +.TP 7 +\ 0 +Successful completion. +.TP 7 +>0 +An error occurred. +.sp +.SH CONSEQUENCES OF ERRORS +.LP +Default. +.LP +\fIThe following sections are informative.\fP +.SH APPLICATION USAGE +.LP +The user who is invoking \fIuudecode\fP must have write permission +on any file being created. +.LP +The output of \fIuuencode\fP is essentially an encoded bit stream +that is not +cognizant of byte boundaries. It is possible that a 9-bit byte target +machine can process input from an 8-bit source, if it is +aware of the requirement, but the reverse is unlikely to be satisfying. +Of course, the only data that is meaningful for such a +transfer between architectures is generally character data. +.SH EXAMPLES +.LP +None. +.SH RATIONALE +.LP +Input files are not necessarily text files, as stated by an early +proposal. Although the \fIuuencode\fP output is a text file, that +output could have been wrapped within another file or +mail message that is not a text file. +.LP +The \fB-o\fP option is not historical practice, but was added at the +request of WG15 so that the user could override the target +pathname without having to edit the input data itself. +.LP +In early drafts, the [ \fB-o\fP \fIoutfile\fP] option-argument allowed +the use of \fB-\fP to mean standard output. The symbol +\fB-\fP has only been used previously in IEEE\ Std\ 1003.1-2001 as +a standard input indicator. The developers of the +standard did not wish to overload the meaning of \fB-\fP in this manner. +The \fB/dev/stdout\fP concept exists on most modern +systems. The \fB/dev/stdout\fP syntax does not refer to a new special +file. It is just a magic cookie to specify standard +output. +.SH FUTURE DIRECTIONS +.LP +None. +.SH SEE ALSO +.LP +\fIumask\fP() , \fIuuencode\fP +.SH COPYRIGHT +Portions of this text are reprinted and reproduced in electronic form +from IEEE Std 1003.1, 2003 Edition, Standard for Information Technology +-- Portable Operating System Interface (POSIX), The Open Group Base +Specifications Issue 6, Copyright (C) 2001-2003 by the Institute of +Electrical and Electronics Engineers, Inc and The Open Group.
