hey guys,
I tried searching but most 'search and replace' questions are related to one liners.

Hello,
I'm trying to figure out how to use sed or awk to delete single lines in a file. By single, I mean lines that are not touching any other lines (just one line with white space above and below).
Example:
one

There are multiple }; lines. I'm curious how to delete the correct one only.

spottopgm(1L)spottopgm(1L)NAME
spottopgm - convert SPOT satellite images to Portable Greymap format
SYNTAX
spottopgm [-1|2|3] [Firstcol Firstline Lastcol Lastline] inputfile
OPTIONS
-1|2|3 Extract the given colour from the SPOT image. The colours are infra-red, visible light and ultra-violet, although I don't know
which corresponds to which number. If the image is in colour, this will be announced on standard error. The default colour is 1.
Firstcol Firstline Lastcol Lastline
Extract the specified rectangle from the SPOT image. Most SPOT images are 3000 lines long and 3000 or more columns wide. Unfortu-
nately the SPOT format only gives the width and not the length. The width is printed on standard error. The default rectangle is
the width of the input image by 3000 lines.
DESCRIPTION
Spottopgm converts the named inputfile into Portable Greymap format, defaulting to the first color and the whole SPOT image unless speci-
fied by the options.
INSTALLATION
You must edit the source program and either define BIG_ENDIAN or LITTLE_ENDIAN, and fix the typedefs for uint32_t, uint16_t and uint8_t
appropriately.
BUGS
Currently spottopgm doesn't determine the length of the input file; this would involve two passes over the input file. It defaults to 3000
lines instead.
Spottopgm could extract a three-color image (ppm), but I didn't feel like making the program more complicated than it is now. Besides,
there is no one-to-one correspondence between red, green, blue and infra-red, visible and ultra-violet.
I've only had a limited number of SPOT images to play with, and therefore wouldn't guarantee that this will work on any other images.
