How can I launch a program that requires a path and that path has spaces or special characters in them if (as far as I can tell) .desktop launchers doesn't seem to support escape characters?
View 1 RepliesI have recently upgraded to a VPS for the purpose of web hosting a group of sites related to my business.The reason for the upgrade was because we wish to run a shopping cart software which required greater memory for PHP and the VPS was the most economic solution. So, I have very basic linux knowledge but I am the definition of a newbie when it comes to going further than just scratching the surface of server configuration! I have successfully hosted our main site for a number of weeks but recently the postfix service stopped sending mail. I have Plesk Control Panel installed and postfix continually shows as not started even though in SSH the service status is definitely running - I have gone through the troubleshooting checklist here (http://www.postfix-book.com/debugging.html#d0e6) but can't get any further than section 2.1 as when running the host command (#host relay-test.mail-abuse.org), I get # -bash: host:command not found. I've gone further in the document but not found any issues...
When postfix was working properly (i.e. sending emails!), the plesk CP showed the service as started and all emails from the website were sending as normal. The mailq command is showing the messages stuck in the mailq and the maillog shows the following:- http://pastebin.centos.org/36446 - these are the latest few pages.To check the configuration and basic elements I have flushed the mailq (which shows a stack of messages waiting) and I have also spent a long time (2 weeks) reading up on the parameters that should be in main.cf and master.cf.I have found that when I 'telnet localhost 25' I get the following response...[root@s15397216]# telnet localhost 25Trying 127.0.0.1...Connected to localhost.Escape character is '^]'.
the problem is how to have a "backslashed R", looking at here and picking up Combining Diacritical Marks you can see all the unicode combining diacritical marks like the one to have a "slashed R" that is U+0338, so if you type R and ctrl>shift>U 0338 >return you obtain R̸,but if you want a "backslashed R" and you type R and ctrl>shift>U 20e5 >return you obtain R⃥, and it isn't what you wantto do this you can use also gucharmap or kcharselect, I tried and them work for U+0338 and doesn't work for U+20e5, so, thinking that it was a gucharmap problem I mailed to gnomebugs here , I red this too here:
Combining Diacritical Marks for Symbols U+20D0 U+20FF (84008447)

Unix: Caslon
and installed fonts, Arial Unicode MS and Caslon, that seems to support U+20D0 - U+20FF (my is U+20e5, so it should be in the range) Combining Diacritical Mark, but it doesn't work, and at the end him suggest me to ask help to my "distrution's support forums", so here I am , Why I cannot have a "backslashed R"??
Ok, so I find myself ripping audio CDs frequently, which I then lame to mp3's to put on my media player. I usually define the --ta and --tl (artist and album) ID3 tags and batch encode each album, but don't bother with the track tags as I'd have to do each one seperately.
So, I'm working on a script to do all this for me, extracting info from 'pwd' etc. to fill in the blanks for --ta, --tl and --tt (track name). All is working well, except that I can't get sed to pass on the "" character to lame to escape spaces.
Here's what I've got so far: (trouble spot is bolded - no need to pay attention to the rest of it)
Code:
All this does is pass a 'space' on to lame, which it takes as an invalid argument.
I have a username like jim@hisdomain.com .
Unfortunately, i have a software that needs a url like ftp://user@host.
I try ftp://jim@hisdomain.com@thehost but it fails and is the same if i try ftp shell command ftp jim@hisdomain.com@thehost .
The ftp command thinks the host is just after the first "@", and try to connect to hisdomain.com@thehost
Is there any escape character fort the at character?
Usually if I have to replace a character in a string I used the sed /s/ command. However, I am having some difficulty in doing the same thing when I have the following string in a variable in my shell script and I need to replace all the forward slashes ("/") to backslashes ("").
For example, this is what I am doing:
Code:
Not sure how to escape the slashes in this case.
1.What character instructd the shell to interpret a special character as an ordinary character?
2.What directory contains some of the utilities available on the system in the form of binary files?
3. What command is used to search the location of a utility?
4. What command is used to instruct the editor to write the file and quit the editor?
5. What key quits the more utility and displays the shell prompt?
6. What command starts a child shell as the super user, taking on root's identity and environment?
7. Which wildcard characters can be used for searching all the files in the system that start with "A"?
8. The user name or login name of the super user is????

I'm using 'Adobe Flash plug-in 10.3.183.4ubuntu0.11.04.1', installed from the package repos on kubuntu, and since the last update, it has broken all flash functionality in both rekonq and firefox.I have tried removing and reinstalling the package multiple times, both with and without the browsers open. Can anyone suggest a way to restoring functionality?
View 7 Replies View RelatedI was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.
When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.

The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:

I'm having trouble getting compiz to work on my Laptop. It worked for a while and then I turned on Shift Switcher and a message popped up saying..."The new value for the button binding for the action Terminate in plugin Shift Switcher conflicts with the action Zoom Window of the Scale Addons plugin. Do you wish to disable Zoom Window in the Scale Addons plugin?" I was given the option of Set Terminate anyway, Don't set Terminate, and Disable Zoom Window. I clicked Don't set Terminate and ever since the only thing that works in compiz are the bindings in the general options. I've used synaptic to completely remove and then reinstall compiz but the problem persist. Something else weird, all of the changes I made are still there, even after complete removal, but they don't work?

View 8 Replies View RelatedI just recently (about an hour ago) installed Ubuntu Netbook edition on my old laptop, and I was greeted with the message, that unity could not be run due to some sort of missing driver...fair enough, I was then greeted with the default Ubuntu desktop, I installed all my needed software (wine, google chrome) and installed the missing display drivers. I then rebooted the system, and once again I am stuck with the default desktop, and not the Unity interface. I checked the software center, and it says Unity IS in fact installed.. And yet I cannot make it appear. So now I ask you Ubuntu veterans. How do I make it work?

One way is to use a triple-quoted string asshown previously or you can use an escape sequence for the newline character - toindicate the start of a new line. An example is This is the first lineThis is thesecond line. Another useful escape sequence to know is the tab - There are many moreescape sequences but I have mentioned only the most useful ones here."In python:>>> "This is the first lineThis is the second"'This is the first lineThis is the second'>>>

I am using sbackup installed on karmic 9.10.
I am using the gui driven sbackup, and the field below needs a passwrd:
ssh://usernameassword@192.168.1.201:/usr/home/username/BAK/
This is a remote backup to a backup storage server.
Nothing fancy, just need to know how to escape a assword@ were the real password uses non numeric/alpha characters.
my passwd includes an "@" so would i use quotes? backticks? backslashes?
Using a passwd like ab34f67 will not work, i use shift'd chars like ^&*@ so forth in my passwrds.
and i know of course i could just get used to it. but the X minimize and expand buttons on the windows is flip flopped on 10.04 now i dont have a clue how to change it back. it kept all old settings but changed this one little thing and its bothering me. ive been through compiz and appearance and whatever else i thought might change this. but just couldnt figure it out. i prefer my escape to be at the top right of my page. as i expect a majority of u do as well. anyone wanna point me in the right direction?

My goal is to send escape characters from Linux to make scanner's LED blink. I've started with a simple "beep" command:
echo -e "�7"
and it worked. We are using WaveLink emulator and the escape sequences for the LED are
echo -e "�33%150;200;5L"
Linux returns me this: 150;200;5L
So, it doesn't work. What am I doing wrong for the LED sequences?
I know that wget will give up after 20 failed connection attempts, but is there any way I can escape without waiting?
View 1 Replies View RelatedI need to occasionally touch a file with the current timestamp as the filename. I would do so this way:
touch `date "+%Y-%m-%d_%H-%M"`.txt
However, I'd like to define an alias for this. When I try adding to the bashrc this:
alias td="touch `date "+%Y-%m-%d_%H-%M"`.txt"
the result is that the filename is the same during the entire session, since the `date ..` gets calculated just once during login...
How can I get the command to expand only when I call the alias? Or must I use a function for this?
Usually when I need to replace some lines in a file, the first tool that comes to mind is sed -i:
sed -i 's|tool:.*|tool: some-tool|'
However, it's inconvenient when there are . characters in the replacement string:
sed -i 's|host:.*|host: 127.0.0.1|' Is there a better tool for this case?
Need little advice running this command.
