Ho do you speed up ubuntu

[christon74]

Hello in there this is Chris
I already have ubuntu 12.04 LTS working just fine but I would like to speed it up a bit. I have watched a video on Youtube which gives a few tips to turn off some start up apps you feel are not absolutely vital.
Here is the line of command they give you to display all the applications on start up when you launch ubuntu:

sudo sed i- "/NoDisplay=true/NoDisplay=false/g"/etc/xdg/autostart/*.desktop
sudo password for XXXX :

And here is what I get each time I type the above in the terminal:


Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...

-n, --quiet, --silent
suppress automatic printing of pattern space
-e script, --expression=script
add the script to the commands to be executed
-f script-file, --file=script-file
add the contents of script-file to the commands to be executed
--follow-symlinks
follow symlinks when processing in place
-i[SUFFIX], --in-place[=SUFFIX]
edit files in place (makes backup if extension supplied)
-l N, --line-length=N
specify the desired line-wrap length for the `l' command
--posix
disable all GNU extensions.
-r, --regexp-extended
use extended regular expressions in the script.
-s, --separate
consider files as separate rather than as a single continuous
long stream.
-u, --unbuffered
load minimal amounts of data from the input files and flush
the output buffers more often
--help display this help and exit
--version output version information and exit

If no -e, --expression, -f, or --file option is given, then the first
non-option argument is taken as the sed script to interpret. All
remaining arguments are names of input files; if no input files are
specified, then the standard input is read.

Is it not fast enough??

If it ain't broke don't fix it.

That being said if you still want to mess about your hyphen was the wrong way

sudo sed i-
should be
sudo sed -i

Thanks. Solved.

There are some apps I have never needed and never used like Ubuntu-One and Bluetooth.

just because they are on the disk it doesn't mean they are slowing the operating system they are onyl taking disk space. and they take a very small part of disk space...

I think OP is concerned about "start up" time, not disk space.

Done, done, and done, but yes, that is how you do it.

Can you give a link to this video?
