General :: Searching Content Of The File Using File Browser Nautilus?

May 27, 2011

I'm using rhel6. Using File Browser Nautilus 2.28.4 I could easily locate any file I'm interested in by it name. I'd like to use this File Browser to locate the file name based on it content e.g. based on some word in the text file. It doesn't work for me that way ... My question: does Nautilus support the search of file based on it content or only based on the name of the file itself?

Programming :: Sed - Save Output To File With Filename From Content Of Another File?

Feb 28, 2011

My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Ive named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:

sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.

General :: Parsing Delimited File And Variable Scripting?

Sep 23, 2010

I did some searches and after a few hours was able to get what I needed. What I didn't find was a fully encompased means of what I'm used to in the windows world in working with delimted files. Hopefully this is helpful to others and if there is something better or leaner way, even better.We have an issue where managing printers, just viewing on RHEL w/ sys-conf-prtr we lose any number of, up to ~30 printers from lpadmin. Rather than stare and compare to find the missing ones, I wanted to make an intuitive script. This is what I came up with.

Ubuntu Networking :: Other File That Stores The Network Configuration Content Besides The Int?

Oct 1, 2010

For Ubuntu 10.04, I can configure the network by "Network Connections". This configuration is done by doing the following operation sequences(System->Preferences->Network Connections->wired->auto eth0). Then I can connet to and browse the internet. If I type the command "ifconfig", I can see the ip I configured for eth0. Part of the content is as blow:

Quote:

ifconfig
eth0
inet addr:192.168.28.31 Bcast:192.168.28.255 Mask:255.255.255.0

But in the "interfaces" file, there is no eth0 content. The whole content is simply as below:

Quote:

cat /etc/network/interfaces
auto lo
iface lo inet loopback

I think there should be other files that keep the eth0 configuration content.

General :: Scripting - Move A List From A Text File To Directory ?

Jan 10, 2011

I'm sure I've done this before and am having a brain fart.

I have run into this a couple of time this last month:

I have a list of torrent files (blahblahhexblah.torrent) saved in a text file. I would like to read the text file and populate the client directory.

I can echo the file using:

But I cannot remember how to pipe the output into the directory, nor can I find any resources that describe the process.

Interestingly enough, I've had a couple of opportunities to do similar tasks with passwords and privileges and even across the LAN in the last few days. Solving this problem will help me solve the others for next time.
