Read section of file and take decision
Hi,

My requirement is that I've to read a config file having below info
Code:
 
Oracle
number|double;integer  -> user can put multiple values here
blob|binary
varchar2|string
varchar|string
number(p,s)|decimal
timestamp|date/time
and so on ....
 
Sybase
bigint|bigint
datetime|date/time
money|decimal
smallint|small integer
and so on ....

In the script I take a XML file as an input and extracts the source database and source & target tables' field's datatype info as below:

Quote:
$src_database - variable could have values as "Oracle", "Sybase", "Teradata",etc
$src_datatype - variable could have values as "number", "timestamp", etc (for Oracle) & "money", "smallint",etc (for Sybase) from SOURCE table
$tgt_datatype - variable could have RHS values as shown in config file from TARGET table
What I want to achieve is that
Code:
 
if $src_database = "Oracle" ;then
          read only Oracle section of the config file
   if $src_datatype = "number"; then 
          get the right hand side value i.e. "double" & "integer" and check if 
          either of the value matches with the $tgt_datatype then
          echo "matches"
   else
          echo "doesn't match"
   fi
fi

Please advice. Thanks.

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.
