NAME
     shar - create file storage archive for extraction by /bin/sh

SYNOPSIS
     shar [-abcsv] [-d delim] [-p prefix] files

DESCRIPTION
     shar prints its input files with special command lines
     around them to be used by the shell, /bin/sh , to extract
     them later.  The output can be filtered through the shell to
     recreate copies of the original files.

     shar allows directories to be named, and shar prints the
     necessary commands (mkdir & cd) to create new directories
     and fill them.  shar will emit commands to make executable
     plain files executable.  shar will not allow existing files
     such files must be removed by the file extractor.

OPTIONS
     -a   All the options.  The options:  -v -c -b -p <tab>X are
          implied.

     -s   Silent running.  All checking and extra output is
          inhibited.

     -v   Print verbose feedback messages about what shar is
          doing to be printed during extraction.  Sizes of plain
          files are echoed to allow a simple validity check.

     -c   Check file size on extraction by counting characters.
          An error message is reported to the person doing the
          extraction if the sizes don't match.  One reason why
          the sizes may not match is that shar will append a
          newline to complete incomplete last lines; shar prints
          a message that mentions added newlines.  Another reason
          why the sizes may not match is that some network mail
          programs remove non-whitespace control characters.
          shar prints a message that mentions control characters
          to the extractor.

     -b   Extract files into basenames so that files with
          absolute path names are put into the current directory.
          This option has strange effects when directories are
          archived.

     -d   Use this as the ``end of file'' delimiter instead of
          the default.  The only reason to change it is if you
          suspect an file contains the default delimiter:
          SHAREOF.

     -p   Use this as the prefix to each line of the archived
          files.  This is to make sure that special characters at

          the start of lines are not eaten up by programs like
          mailers.  If this option is used, the files will be
          extracted with the stream editor sed rather than cat so
          it is more efficient and portable to avoid setting the
          prefix, though perhaps less safe if you don't know what
          is in the files.
