And, the .* would allow for one or more comma-separated fields, both in the middle as well as at line end. You might want to anchor the regex at line end, too. Proposal (untested)


Code:
sed -r 's/^([^,]*,){2}bcd,.*,([^,]){4}[^,]*$/&,\2/'

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. SEE ALSO
wmanager(1), wmanager-loop(1), wmanagerrc-update(1), X(7x) HISTORY
