NAME
uuencode, uudecode, b64encode, b64decode -- encode/decode a binary file SYNOPSIS
uuencode [-m] [-o output_file] [file] name uudecode [-cimprs] [file ...] uudecode [-i] -o output_file b64encode [-o output_file] [file] name b64decode [-cimprs] [file ...] b64decode [-i] -o output_file [file] DESCRIPTION
The uuencode and uudecode utilities are used to transmit binary files over transmission mediums that do not support other than simple ASCII data. The b64encode utility is synonymous with uuencode with the -m flag specified. The b64decode utility is synonymous with uudecode with the -m flag specified. The uuencode utility reads file (or by default the standard input) and writes an encoded version to the standard output, or output_file if one has been specified. The encoding uses only printing ASCII characters and includes the mode of the file and the operand name for use by uudecode. The uudecode utility transforms uuencoded files (or by default, the standard input) into the original form. The resulting file is named either name or (depending on options passed to uudecode) output_file and will have the mode of the original file except that setuid and exe- cute bits are not retained. The uudecode utility ignores any leading and trailing lines. The following options are available for uuencode: -m Use the Base64 method of encoding, rather than the traditional uuencode algorithm. -o output_file Output to output_file instead of standard output. The following options are available for uudecode: -c Decode more than one uuencoded file from file if possible. -i Do not overwrite files. -m When used with the -r flag, decode Base64 input instead of traditional uuencode input. Without -r it has no effect. -o output_file Output to output_file instead of any pathname contained in the input data. -p Decode file and write output to standard output. -r Decode raw (or broken) input, which is missing the initial and possibly the final framing lines. The input is assumed to be in the traditional uuencode encoding, but if the -m flag is used, or if the utility is invoked as b64decode, then the input is assumed to be in Base64 format. -s Do not strip output pathname to base filename. By default uudecode deletes any prefix ending with the last slash '/' for security reasons. EXAMPLES
The following example packages up a source tree, compresses it, uuencodes it and mails it to a user on another system. When uudecode is run on the target system, the file ``src_tree.tar.Z'' will be created which may then be uncompressed and extracted into the original tree. tar cf - src_tree | compress | uuencode src_tree.tar.Z | mail user@example.com The following example unpacks all uuencoded files from your mailbox into your current working directory. uudecode -c < $MAIL The following example extracts a compressed tar archive from your mailbox uudecode -o /dev/stdout < $MAIL | zcat | tar xfv - SEE ALSO
basename(1), compress(1), mail(1), uucp(1) (ports/net/freebsd-uucp), uuencode(5) HISTORY
The uudecode and uuencode utilities appeared in 4.0BSD. BUGS
Files encoded using the traditional algorithm are expanded by 35% (3 bytes become 4 plus control information). BSD

NAME
uudecode, uuencode -- encode/decode a binary file SYNOPSIS
uuencode [-m] [-o output_file] [file] name uudecode [-cips] [file ...] uudecode [-i] -o output_file [file] DESCRIPTION
The uuencode and uudecode utilities are used to transmit binary files over transmission mediums that do not support other than simple ASCII data. The uuencode utility reads file (or by default the standard input) and writes an encoded version to the standard output, or output_file if one has been specified.

The following options are available for uudecode: -c Decode more than one uuencode'd file from file if possible. -i Do not overwrite files. -o output_file Output to output_file instead of any pathname contained in the input data. -p Decode file and write output to standard output. -s Do not strip output pathname to base filename. By default uudecode deletes any prefix ending with the last slash '/' for security purpose. EXAMPLES

When uudecode is run on the target system, the file ``src_tree.tar.Z'' will be created which may then be uncompressed and extracted into the original tree. tar cf - src_tree | compress | uuencode src_tree.tar.Z | mail sys1!sys2!user The following example unpack all uuencode'd files from your mailbox into your current working directory. uudecode -c < $MAIL The following example extract a compress'ed tar archive from your mailbox uudecode -o /dev/stdout < $MAIL | zcat | tar xfv - LEGACY DESCRIPTION
In legacy operation, uudecode masks file modes with 0666, preventing the creation of executable files. uudecode cannot change the mode of a created file which is not owned by the current user (unless that user is root). In legacy operation, fchmod(2) allows the mode to be changed. For more information about legacy mode, see compat(5). SEE ALSO
