Pomario's questions

I have a 2TB external HDD formatted with exFat that I use to share very large files (>10GB) among Ubuntu, Windows 7 and MacOS.

I am trying to copy the whole content of a directory using

sudo cp -r . /media/user/WD2TB

But I am getting the following output to what seems to be a very long filename

cp: cannot create regular file ‘/media/user/WD2TB/./Pictures/2013/Travel/2013-05-01_05:29_1367382554_Aaaaaaa_Bbbbbbb_Cccccccccc.JPG.xmp’: No such file or directory

Anyone knows why is this happening?

I find Ubuntu (12.10)'s Seahorse intrusive and annoying and I would like to remove it using Ubuntu Software Center. If I do so, could it potentially cause me problems with future Ubuntu upgrades?

I would like to setup Ubuntu to capture motion in my studio and e-mail pictures of anyone who enters it. MS Windows has plenty of software to do this, but now that I switched 100% to Ubuntu, I need a software to accomplish this. Ideas?

I have bunch of ISO images in my hdd and I have their whole content listed inside a text file in the following format:

<immage>.iso, <dir structure>/<filename>.<extension>

example:

OS Backups.iso, ­ubuntu-­12.­04-­desktop-­i386.­iso 
OS Backups.iso, xubuntu-12.04-desktop-i386.iso
OS Backups.iso, background/pictures.jpg
Pictures vacation 2011.iso, documents/cost_estimates.xls
Pictures vacation 2011.iso, italy/img1.jpg
Pictures vacation 2011.iso, italy/img2.jpg

Now I want to issue a grep command against that text file to find files that contain "pictures" in their names. The expected result would be (for the previous example):

Pictures vacation 2011.iso
OS Backups.iso, background/pictures.jpg

Any ideas on how to accomplish something like this using grep? Alternatives? Thanks!

I am trying to understand how to use the stdout as the stdin of another command. To test it, I am trying to use the following command to delete all directories from the current folder.

ls -d -- */ | rm -rf $1

I would expect the result of ls -d -- */ to be piped into the input of the rm, but it does not work. Ideas?

I found the following awesome little script at link

$ find /home/bruno/old-friends -type f -exec sed -i 's/ugly/beautiful/g' {} \;

But I really do not understand the final bit

{} \;

Could someone please explain??

Thanks!

What is the difference in doing

$ MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=384m"

to doing

$ export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=384m"

and is there any side-effect of doing either in an SSH connection?

I have the following code snippet

for num
do
   echo $num
done

But I don't understand why it works! How come does Bash know to loop through my params $1, $2, $3, $... using my personal taste of "num" variable???

I would like to add the current time upon execution of a bash command. I would like it to be in the right hand site so not to be intrusive. The output I am looking for is:

batman@Batcave:~/grails$ ls -l
total 84
drwxr-xr-x 2 batman batman  4096 2011-02-16 09:54 bin
drwxr-xr-x 2 batman batman  4096 2011-02-16 08:24 scripts
drwxr-xr-x 9 batman batman  4096 2011-02-16 08:24 src
batman@Batcave:~/grails$                                                       **10:46:06**

ideas on how to accomplish this??

Apparently Ubuntu 11.10 uses Vim when I type

vi filename

How do I force Ubuntu to use Vi instead?

I am the single user on this Linux machine. I tried the following procedure to protect files, but it does not work as I expected. Could someone explain why?

$ touch file
$ sudo chown root:root file
$ sudo chmod a-w file
$ ls -l file
-r--r--r-- 1 root root 0 2012-02-29 01:06 file
$ rm file
rm: remove write-protected regular empty file `file'? yes
$ ls -l file
ls: cannot access file: No such file or directory

"File" is read-only and owned by root. Why was my regular user able to delete it?

Shotwell lists photos based on when they were taken. While this is fine for single-day "trips" (ie Saturday at the park) it is awefull for photos taken in a lengthy trips (ie My month in Italy) as each day would be an entry on the left panel instead a group. Having over 30K photos organized in directories, is there any way Shotwell will keep my photo structure and create one event per folder?

Since a few days ago, my computer freezes whenever I sync my HDD with an external USB3 drive. When the keyboard gets temporarily a bit responsive I am able to switch to another terminal (Ctrl+Alt+F2) and I see the following image repeating continuously. I am on Ubuntu 11 using LuckyBackup.

What is going on? Is my hdd defective? Is it the external one? Something else?

Many thanks!

I am new to Ubuntu and I would like to uninstall many of the programs I don't use that came with version 11.10 (e.g. games, Tomboy notes, Scan, etc). Though, I am scared of the thought that by doing so - when I upgrade to a new Ubuntu version - my computer might get broken. Is there reason to fear? Or is the Ubuntu upgrade procedure bullet proof?

We are starting our Jenkins CI with the following bash command that I would like understand. Could someone explain what is doing (the only bit I get is "java -jar jenkins.war"). Thanks!

nohup java -jar jenkins.war > $HOME/jenkins.log 2>&1 < /dev/null &

How can I contribute to Ubuntu?

I have been using Open Source software for a few months and loving it. Something is dawning on me, a feeling of wanting to give back. Though, I do not know how to do it, as I do not have money to donate or time to code. Are there alternative ways I can do to help the OSS projects I learned to use and love?

the following error is preventing me from installing anything on Xubuntu 11.10. How can I fix it??

I have had some old VHS digitalized into DVD and used Window's PowerISO software to back them up in my external hdd. The I've got 4 videos that I want to run on Ubuntu 11.10:

• A.bin
• B.bin
• C.bin
• C.cue
• D.bin
• D.cue

How do I watch the video contents inside of those files?

I want to enter the following folder in the terminal:

Milano, Torino (Jan)-Compressed

How should I write the command cd to enter this directory?

Spaces and several other special characters like \, *, ), ( and ? cause problems when I try to use them in the command line or scripts, e.g.:

$ cd space dir
bash: cd: space: No such file or directory

$ cat space file
cat: space: No such file or directory
cat: file: No such file or directory

$ cat (
bash: syntax error near unexpected token `newline'

$ echo content >\
> ^C

$ ls ?
(  )  *  ?  \

How do I enter file or directory names that contain special characters in the terminal in general?
