This sed command will delete all lines that begin with a tab character. I think this is what you want, if I understood your question. And it should be very fast processing that big file.

Hi
Consider the file
this is a good line
when running
grep '\b(good|great|excellent)\b' file5
I expect it to match the line but it doesn't... what am i doing wrong??

vselect
vselect(1Vi)vselect(1Vi)NAME
vselect - select objects from a Vista data file
SYNOPSIS
vselect [-option ...] [infile] [outfile]
DESCRIPTION
vselect copies selected objects from an input file to an output file.
Command line options specify which objects are to be copied. Objects may be selected by type (e.g., all images), by name, by the value of
some attribute, or by position within the input file.
COMMAND LINE OPTIONS
vselect accepts the following options:
-help Prints a message describing options.
-in Specifies a Vista data file from which objects are to be selected.
-out Specifies where to write the selected objects as a Vista data file.
The input and output files can be specified on the command line or allowed to default to the standard input and output streams.
In addition, exactly one of the following options must be used to specify the objects to be selected:
-object i Select the ith object. Objects in the input file are numbered consecutively from 0.
-name name Select any object whose attribute name is name.
-type type Select any object whose type is type.
-attr name value
Select any object having an attribute with the specified name and value.
Finally, any of these selection criteria can be inverted:
-not Reverses the sense of the selection criterion.
EXAMPLES
To select the first object from a file:
vselect -object 0 < infile > outfile
To select the attribute named ``cantaloupe'' from a file:
vselect -name cantaloupe < infile > outfile
To select everything but images from a file:
vselect -type image -not < infile > outfile
To select images with ubyte pixels from a file of images:
vselect -attr nbands ubyte < infile > outfile
