I Posted To Introduce Myself, But My Message Is Not Taken. Why?

I just registered, activated the account, logged out and back in and edited my profile. Then, I was taken to introduce myself. I wrote a message, clicked on "Preview Post" and it looks OK, so I clicked on "Submit New Thread". I get no errors. It just takes me back to the previous screen, my post is not there and it tells me that the system detects I have never posted anything. Why? I'm hoping this one message will go through.

Thanks in advance...

EDIT: Now I see how much of a newbie I am! A sign was telling me my message was to be checked by a moderator, but it flashed so short, that I couldn't finish reading it until now. There must be a few copies of my introduction pending. Sorry!

Install From Flash Drive

Hi all,

I must confess that I haven't posted for more than a year, although I have been reading the emails that your admin staff kindly sends me. I was just about to bother you with a question regarding installing and booting into Linux from a flash drive on laptop with no hard drive in it. However, I just discovered http://www.pendrivelinux.com/, so I'll post my questions there first, since they apparently specialize in this kind of installation. Of course, comments and suggestions here would also be welcome and appreciated.

Thank you,
Bob

Recurring Startup Application

Hi
Kindly refer to following post:
http://www.linuxforums.org/forum/pro...tml#post954718
Here, at post #4, solution given by "LSalab" worked for me. So I added it to startup applications in my cinnamon desktop. But the problem is that, it works only once after every login (when the battery gets lower than 10% so it informs me), and if I charge the battery and again it reaches that threshold point of 10%, the system does not inform me, which means that the startup script only executes once.
here is the script:
Code:
#!/bin/bash
while [[ `acpi | cut -d ' ' -f 4 | grep -Po '\d+'` -gt 10 ]]
do echo -ne "\r`acpi`"
sleep 5
done
notify-send -t 60000 'Low Battery' 'Battery charging of your system is below 10%. Kindly Plug charger. Thanks.'
echo ''
mplayer /usr/share/sounds/freedesktop/stereo/phone-outgoing-busy.oga -loop 0

So my question is that, how can I make this script recurring at every threshold level?
Regards

Permissions Question

Hello,

Just starting with Linux and I have a question about permissions. When I run ls on /bin/bash I get the following permissions output:

-rwxr-xr-x .......

Why are there 4 letters on the owner's permissions, namely the last "r" which I have put in bold? Since there are only 3 types - r, w and x, what's the point of the second "r" ?

Thanks

/etc/shadow Question

Looking at the /etc/shadow file, for some of the system services accounts there are "*" and for others "!!" in the password field.
Searching online I have only found that !=*, i.e. prevent use for log-in, but, if true, what is the actual difference? Why not use "*" on all of them? And why double exclamation point?

CrossOver Or Wine (or Other Interface)

Sorry in advance, I first posted the question in the Software Forum, considering there were no replies I thought maybe it was a newb error.

So here goes..

HI everyone,

I am trying to find a way to ditch MS OS's, however, at the present time I Need MS Office, without using a VM, is there a piece of software that you would recommend I install that would enable me to keep my Linux OS (MInt-Mate), and install Office 2010+ (I know WIne works well with older Office versions).

Any and all ideas are greatly appreciated.

ps. Trial and error is fine, for that reason alone I have a laptop-labrat I Use.

Thanks again.

Ubuntu Or Kubuntu

Hi
I've just this minute joined the forum. A message suggested I post my first question so here it is:
I'm using Kubuntu. I know it's Ubuntu with KDE , but I'm just wondering what others think: which is better - ordinary Ubuntu or Kubuntu? I know I can try them out for myself, but I'm just wondering what the consensus of opinion is.

Extract Info And Find/count Strings From Blocks Inside Text File

Hello

I have a text file which has blocks like
Code:
dir1/dir2/dir3/name_run_number1:
line1_run_number1_part1
line2_run_number1_part2
line3_run_number1_part3...

Each block is separated with a blank line and there is the ":" in the "header" of each one while each block carries the same "number1" after "run_" suffix
What I want to do is for each block, extract the "number1" as shown in the first line and then for the lines below count from 1-20 and give a message if a "partX" line is missing. Any bash or python would be fine

Thanks
