Building hierarchy with the list

Hi All,

Sorry for more question today. I am having a text file . Like below

Code:
704925680_TOTAL->MANUAL->TT IOR GSB
775116444_TOTAL->POO TO->TT
-572275295_TOTAL->MANUAL->MTO
-611408278_TOTAL->PRIE LEL
456690129_TOTAL->BTT TOO
475919266_TOTAL->MANUAL->COM
-172680236_TOTAL->BTT TOO->MTO
481202389_TOTAL->MANUAL->TT COM
655296953_TOTAL->POO TO->COLE
-434977163_TOTAL->POO TO->SPI
-766208436_TOTAL->MANUAL->TT 3W GSB
-1903630442_TOTAL->COLE
-541283452_TOTAL->MANUAL->CRT

These are the hierarchical data. But not on the hierarchy order. If you see all fall on total and after total the next data come in the file in the example above it is MANUAL. But the MANUAL data are not group and scattered. I am trying to bring these on the group. The data to be grouped always falls after -> . The example I have given is 3 level we may have 4 or level. The above files needs to be grouped as below



Code:
-766208436_TOTAL->MANUAL->TT 3W GSB
704925680_TOTAL->MANUAL->TT IOR GSB
-572275295_TOTAL->MANUAL->MTO
-541283452_TOTAL->MANUAL->CRT
481202389_TOTAL->MANUAL->TT COM
475919266_TOTAL->MANUAL->COM
-611408278_TOTAL->PRIE LEL
456690129_TOTAL->BTT TOO
-172680236_TOTAL->BTT TOO->MTO
775116444_TOTAL->POO TO->TT
655296953_TOTAL->POO TO->COLE
-434977163_TOTAL->POO TO->SPI
-1903630442_TOTAL->COLE

Is there any easy way to do in Perl or awk. I am thinking to do C code. Any help will be great.

NAME
ppmtosixel - convert a portable pixmap into DEC sixel format SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC LJ250 color inkjet printer. If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file. OPTIONS
-raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com- pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni- tude larger than a compressed file and prints much slower. -margin If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci- fied, a 1.5 inch left margin will offset the image. PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?. BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation. SEE ALSO
