sed replace characters using a wildcard
Hello,

I have some data that looks like the following,
Code:
>  <SALTDATA> (OVS0199262)
HCl

>  <IDNUMBER> (OVS0199262)
OVS0199262

>  <SUPPLIER> (OVS0199262)
TimTec

>  <EMAIL> (OVS0199262)
info@timtec.net

>  <WEBSITE> (OVS0199262)
http://www.timtec.net

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,
Code:
>
HCl

>
OVS0199262

>
TimTec

>
info@timtec.net

>
http://www.timtec.net

where I want the output,
Code:
>  <SALTDATA>
HCl

>  <IDNUMBER>
OVS0199262

>  <SUPPLIER>
TimTec

>  <EMAIL>
info@timtec.net

>  <WEBSITE>

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,

LMHmedchem

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.

wmanager

WMANAGER(1)						    BSD General Commands Manual 					       WMANAGER(1)

NAME

     wmanager -- choose a window manager and launch it

SYNOPSIS

     wmanager [OPTIONS ...]

DESCRIPTION

     The wmanager program displays a choice of the window managers listed in the ~/.wmanagerrc file.  When one is picked, the related command is
     written to standard output, intended to be used by shell scripts.	If the program is exited without choosing a window manager, ``-1'' is
     written to standard output.

     -fg COLOR
	     Set the foreground color.

     -bg COLOR
	     Set the background color.

     -bg2 COLOR
	     Set the widget background color

     -di[splay] host:n.n
	     Set the X display.

     -dn[d], -nod[nd]
	     Enable/disable drag & drop, probably does nothing.

     -g[eometry] WxH+X+Y
	     Set the window size and location.

     -i[conic]
	     Start as iconified.

     -k[bd], -nok[bd]
	     Enable/disable keyboard support.

     -na[me] CLASSNAME
	     Set the X window class.

     -s[cheme] SCHEME
	     Unknown, probably does nothing useful.

     -ti[tle] WINDOWTITLE
	     Set the window title.

     -to[oltips], -not[ooltips]
	     Enable/disable tooltips, probably does nothing.

EXAMPLE

     To start using wmanager, create a ~/.wmanagerrc file - generally with wmanagerrc-update(1) - and add something like the following at the end
     of your ~/.xsession file:

	   WM="$(wmanager -geometry +570+585)"
	   ...
	   exec $WM

     See also wmanager-loop(1) for a nicer way to start wmanager.

     The wmanager program was written by Meik Tessmer in 1999.	This manual page was originally written in perldoc format by Tommi Virtanen in
     2000, and converted to mdoc format by Peter Pentchev in 2008.
