I have some data that looks like the following,
I need to remove the data in the parentheses and the space following the final > in those lines. The value in parentheses is different in each record.
I tried sed, sed 's/>\ \(.*\)/>/g' infile > modfile
to me, this reads, find ">" followed by 1 space, followed by open parentheses, followed by any number of any character, followed by close parentheses and replace with ">".
It seems like this should work, unless I don't have the syntax right. Instead, I am getting the output,
where I want the output,
Here, sed seems to be matching the first greater than on the line instead of the second.
What am I missing here? I am guessing I need to escape the parentheses differently since they have their own meaning in sed.
thanks,

I found this, sed 's/>[^>]*$/>/'
which works by removing everything after the second >. This seems to give me what I want.
I would still like to know what was wrong with my sed command above if anyone can comment.

How can I use sed to replace a ctrl character such as 'new line' (\0a) to something else? Or any other good command can do this job?
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.
