NAME

       hexcurse - an ncurses-based hex editor

SYNOPSIS

       hexcurse [ -?  |  -help ] [ -a ] [ -r rnum ] [ -o outputfile ] [ [ -i ] inputfile ]

DESCRIPTION

       hexcurse  is  an  ncurses-based hexeditor utility that is able to open, modify, and save a
       file to disk while providing useful editing and searching options.

OPTIONS

       -?  |  -help   Prints out the command usage info

       -a             Specifies the addresses to be output in decimal format initially.

       -r rnum        Specifies the number of characters  per  line  that  the  hexeditor  should
                      output.   If  rnum is either less than 1 or greater than the columns of the
                      current terminal, hexcurse will fill the terminal width, just as if the  -r
                      was not specified.

       -o outputfile  Specifies the output file to be written to by default.

       [-i] inputfile Specifies  the  input file to be read in.  -i is not needed if inputfile is
                      the last argument on the line.

INTERACTIVE OPTIONS

       F1 | ctrl+?    Shows key command help.

       F2 | ctrl+s    Save the current file.

       F3 | ctrl+o    Opens a file.

       F4 | ctrl+g    Goto a certain location in the current file.  Depending on  which  way  the
                      addresses   are  being  viewed  at  the  moment,  the  search  will  behave
                      differently.  If the addresses are currently in hex format, the search will
                      search  as  if the input was given in hexadecimal format.  If the addresses
                      are in decimal format, the function will search for the address in decimal.

       F5 | ctrl+f    Search for a certain string in the current file.  Depending on which window
                      the  user is currently editing in, this search will behave differently.  If
                      editing in the hex window, the input should only be in hexadecimal, and  it
                      will search for the hexadecimal "string."  If the current editing window is
                      the ASCII window, the input should be ASCII characters, and the search will
                      find that ASCII string in the file.

       F6 | ctrl+a    Switch between hexadecimal address values and decimal address values.

       F7 | TAB       Switch between the hexadecimal and ASCII editing windows.

       F8 | ctrl+q | ctrl+x
                      Exit out of the program.

       Page Up | ctrl+u
                      Scroll one 'page' up.

       Page Down | ctrl+d
                      Scroll one 'page' down.

       Home | ctrl+t  Returns to the top of the file.

       End | ctrl+b   Jumps to the bottom of the file.

       ctrl+z         Undo the last modification.  Can be used multiple times.

       Esc            Escapes out of the save, open, goto, and find prompts.

BUGS

       On some terminals the function keys will not work.

       Support  for  resizable  terminals  is  still  a  bit rudimentary.  At this time, when the
       terminal is resized, the cursor is positioned at the beginning of the file.  This will  be
       corrected  in  the next release.  There is also an issue where the labels on the bottom of
       the screen do not resize correctly.  A fix for the latter is in the works.

TODO

       When we get the time, we would like to implement the ability to  insert  and  delete  data
       from the file.  Please e-mail us with any additional suggestions.
