Extracted files are written to the current +directory. +.PP +\fIfile\fR is an optional filename or wildcard pattern, +such as \fIautorun.sys\fR or \fI*.sys\fR. If not +given, the default is \fI*.*\fR. \fIfile\fR is case insensitive: +\fIreadme.txt\fR is equivalent to \fIREADME.TXT\fR, and +\fI*.txt\fR is equivalent to \fI*.TXT\fR. If a wildcard is used, +most shells will require the argument +to be quoted, to avoid the shell's normal wildcard expansion. The +wildcard semantics are similar to those of Atari DOS or POSIX sh, but +are not identical to either. +.PP +\fIdir\fR is the directory to extract files to. If omitted, the default +is the current directory. If \fIdir\fR is to be given, \fIfile\fR must +also be given (although it may be specified as \fI""\fR, equivalent +to \fI"*.*"\fR). +.PP +\fBatrextr\fR does not take any other options. +.SH NOTES +DOS 2.5 disk images are not fully supported. Specifically, \fBatrextr\fR +is unable to extract files that use sectors above 720 (those +that are listed with \fI<\fR, in \fBatrdir\fR or Atari DOS 2.5). These +files will be silently skipped, exactly as Atari DOS 2.0S does when reading +a 2.5 enhanced density disk. +.PP +MyDOS subdirectories are not supported. Only files in the root directory +of a disk image can be extracted. +.PP +MyDOS large disk images (aka hard disk images) are supported, though +without subdirectory support, \fBatrextr\fR can't extract most of the +files in a typical hard disk image. +.PP +XFD format images are not supported. Neither are SpartaDOS, Atari DOS 3/4, +DOS XE, or other non-standard DOS formats. +.PP +There should be options to translate Atari EOL characters to and from +UNIX newlines, and to convert the extracted filenames to lowercase. +.PP +Exit status is zero if all files were extracted successfully, or +non-zero if any errors occurred. In case of a non-zero return, +some files may still have been extracted (though some or all of them +may be truncated or corrupt). +.SH AUTHOR +Ken Siders <\fBatari8bit@columbus.rr.com\fR> +.PP +Man page by B.
