Example of substitute example:
$ echo "$(echo "TRUE" | sed -e 's/TRUE/FALSE/g')"
FALSE
"g" is for "global"
Example with variables (use full quotes):
$ X="abcd"
$ Y="xyz"
$ echo $X | sed -e "s/${X}/${Y}/"
xyz
If a variable uses a "/" inside it, use a different "delimiter" (the
first character after the "s" tells sed what the delimiter is):
$ X="./abcd"
$ Y="./xyz"
$ echo $X | sed -e "s|${X}|${Y}|"
./xyz
This works inside of vi too.
I recall years ago when using “vi’ clones. Before VIM became popular and I
would use other clones. They generally only supported / as a delimiter, and
using something different (I normally use -) was an example of where their
compatibility broke down.
Hi Kevin,
This I did not know. I still use vi a lot too. Thank
you for sharing!

How to use sed with variables with slashes in them.
Hi All,
This took me an very frustrating hour to figure out. Especially
since I was looking for something like awk's "-F" command.
I hope this save someone else from pulling their hair out!
(I was trying to do a substitution with a ton of forward slashes
in it from a variable. H!)

Example of substitute example:
$ echo "$(echo "TRUE" | sed -e 's/TRUE/FALSE/g')"
FALSE
"g" is for "global"
Example with variables (use full quotes):
$ X="abcd"
$ Y="xyz"
$ echo $X | sed -e "s/${X}/${Y}/"

If a variable uses a "/" inside it, use a different "delimiter" (the
first character after the "s" tells sed what the delimiter is):
$ X="./abcd"
$ Y="./xyz"
$ echo $X | sed -e "s|${X}|${Y}|"

From the kompozer URL: Latest stable version: 0.7.10 (2007-08-30) This is a beta version (by release number, albeit "stable" by declaration) that is more than seven years old. I have used kompozer in the past, but komopozer was not keeping up with some of the "new" features that appear in certain web pages. As BlueGriffon uses the current Firefox "internals", it more closely adapts to certain of these features as I recall from direct use.

Re: Mate 1.8
The only documentation I can find for the dconf settings for Mate is what is available under "Description" when you click on a setting in dconf-editor. That is presumably at least accurate, even if you have to hunt around to find what you want. On 04/12/14 22:12, Yasha Karant wrote: Problem solved. Are the dconf-editor edited fields (variables) (well) documented anywhere? I did a web search on this issue and a found a reference that this had been solved in Mate 1.8 (at least on ubuntu). As I show my research students, a MS Win 8, Mac OS X, Gnome 3, or KDE Plasma interface is not as efficient as a Gnome 2 style interface for non-touch-screen machines; trackpads and touchscreens require ergonomic calibration that may be too sensitive for some hands/fingers. Mate is much better.

However, Mate is an EPEL port to EL7. I have been attempting to use Gnome 3, both Classic as well as Frippery; but I find that Gnome 3 lacks specific functionalities that I prefer. Evidently, Mate is a port/clone of Gnome 2 for distributions using Gnome 3, including EL7. I have installed Mate 1.8.1 as well as the applets, etc., from the EPEL list in the Add/Remove Software GUI. However, the window selector grid has a fixed 4 windows, and the right click Preferences on the selector does not allow me to increase the number of workspaces. A search on the web reveals that this is supposedly fixed in Mate 1.8 , but is not on my machine. Does anyone have a solution? Supposedly Oracle EL 7 uses Gnome 2. Is it possible to use the Oracle EL 7 rpms to install Gnome 2?
