Wrench Using sed to delete one regular pattern with conditions
Hi All ,

I am having a file like this

INPUT FILE

###############################
Code:
addfd_mjlala kksks sksks ks 
annsns_bbox_2 (sksksk ksks )
adnndn_nsns_bbox_3 (( jsjsdj sjsj )
malm_dkdm lsls lsl
mdndk_mkmd_dkd_bbox_4_kdkd [jkssk jsjs[]
ksksk skksk_bbox_jsj_KSK ((jsjsj jsjsj )

#############################################

OUTPUT FILE

#########################################
Code:
addfd_mjlala kksks sksks ks 
annsns (sksksk ksks )
adnndn_nsns (( jsjsdj sjsj )
malm_dkdm lsls lsl
mdndk_mkmd_dkd  [jkssk jsjs[]
ksksk skksk ((jsjsj jsjsj )

##############################################

So you can see we have file with some instances having _bbox
I need a script which can delete the _bbox till the end of the word but retain the other word in the same line

I am using script like this

Code:
sed  's/_bbox.*$//g' INPUT_FILE > OUTPUT_FILE

But it is deleting the second word from each line having bbox

Thanks
Kshitij

ppmtosixel

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

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.
