Ubuntu :: Convert Jpg/png To Eps Within Shell?
Dec 20, 2010
I need to frequently convert jpg/png to eps. Usually I use GIMP and it works fine. I would like to perform the conversion via shell (maybe with a script) without opening any graphical window. I used the command convert of ImageMagick but the quality is poor, I assume that it is because of some parameter to set I do not know. I know the question is trivial and full of posts around but I'm wasting time without finding what I'm really looking for.

I have some checksums.md5 verification files from an ntfs external drive, but using windows notation: instead of /, spaces between file names (not escaped), reserved shell characters (like (, &, ', to name a few). The checksums.md5 has a bunch of checksums and filenames:
[code]...
I want to use this checksums.md5 to verify the files that I've copied to my machine: but I'm on a Linux, so I need to convert the names inside checksums.md5 from Windows to Linux to use the md5sum utility from the shell. The first line in my example would become: f12f75c1f2d1a658dc32ca6ef9ef3ffc My Windows & Files (2010)/[bak]/testing.wmv Is there some application for this (converting a file listing, from windows cmd notation, to linux shell notation) or will I need to create a bash script using sed that just "replaces" what is "wrong" with the filenames

Is there tool or a regexp that can convert shell escape characters to HTML code?
As an example, here is a logfile from GNU screen:
Which I would like to convert to something like this:
And send as HTML e-mail to an e-mail address, to archive my work.
Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.

I have a series of input files formatted like this:
Code:
RTREVF, KOG3266 = 111
RTREVF, KOG3294 = 130
RTREVF, KOG3295 = 177
WAGF, KOG3307 = 107
JTTF, KOG3320 = 174
Each line represents a portion of a data matrix. I want to convert the numbers after the "=" to the range of that partition in the matrix such that the output file looks like this:
Code:
RTREVF, KOG3266 = 1-111
RTREVF, KOG3294 = 112-241
RTREVF, KOG3295 = 242-418
WAGF, KOG3307 = 419-525
JTTF, KOG3320 = 526-699

An easy way to convert wav files into mp3 (or ogg).
$ sudo-apt-get install nautilus-script-audio-convert mpg321 vorbis-tools lame nautilus-script-manager.
after that run
$ nautilus-script-manager enable ConvertAudioFile
Now, when you right click on audio file, under 'scripts', you will see ConvertAudioFile option.

I have Ubuntu 9.04 and just installed Sound Converter. I am trying to convert a bunch of .ogg files to mp3 to play on my iPod and it's not working so well. In the Sound Converter options I have is set to convert to high quality mp3. I choose the folder that the files are in and after a moment (slow laptop) Sound Converter populates, I hit 'convert' and it shows that the conversion completes in two seconds. All that it did was create the new folder structure of artist/album but there is nothing in there. Not sure what I am missing. I used Sound Converter before and it worked fine.

I have a lot of .flac files downloaded from several sites. Most of them come with a .cue file, and the .jpg with the cover, etc. It seems it is the intention of the uploader that one rebuilds the original CDDA. However, if I had a stand-alone CD/DVD player with flac I would hardly see the point of converting the flac to cdda. Furthermore, I could even play the flacs with a software player although, in this case, the audio quality would not be so good due to the noise picked up by the signal from the PC digital circuits.

I use aterm and xterm, does anybody know why that is, am I missing a package?

Is there any way I can switch my desktop shell from unity to, say, gnome-shell? I can switch using other console shell I like (bash, csh, fish, etc.). Assume that there is a stable alternative desktop shell, I should be able to choose, too.
(For console shell, we goes to /etc/passwd. But for desktop, I can't find the way to config.)

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"
code....

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

I've created a simple script based menu. This menu will be accessed by only a certain users via ssh.When user logs in, the menu will automatically run. (configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.

I have a situation where I am in a non-interactive shell. I have tried from within my non-interative shell to spawn an interactive shell but my output still does not goto me. Isn't there a way I can somehow go into /proc or somwhere and make the output my /dev/tty1? Or some way else to remedy this?The situation arises because I drop from my restricted shell environment (a sort of CLI interface), into the actual Linux shell. I cannot change the code of the CLI environment I am just faced with being in the linux shell environment and its non-interactive. Its very annoying to have to put > /dev/tty1 after every command I type.
Not to mention it seems damn near impossible to get pagers like more and less to work properly when your in a non-interactive shell.

My Mac crashed, and the Hd is in trouble, however I have Linux, and no windows or anything. So I took my backup DMG, to install it. However I cannot get it on a disk, and Mac cannot boot. Is there a way to convert it to an ISO, then just use Brasero Disk Burner to regularly burn it onto a DVD+DL?
