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?

General :: Filter Find And Du By Content Of Inner File In Subdirectory?

May 30, 2010

I have the following command that I run on cygwin:

find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv

I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each

/d/tmp/subfolder1/somefile.properties
/d/tmp/subfolder2/somefile.properties
/d/tmp/subfolder3/somefile.properties
/d/tmp/subfolder4/somefile.properties

so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:

/d/tmp/,subfolder1,<itssizein KB>
/d/tmp/,subfolder2,<itssizein KB>

and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:

find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv

General :: Reboot Not Required After Changing HOSTS File Content?

Oct 18, 2010

I was having a discussion with someone who asked me whether a Linux OS has to be rebooted when the hosts file is modified. From personal experience, on Windows I change the file but don't reboot and I've seen others do the same thing. I assume Linux has no exception(s), but is there any reason why a reboot is not required (to at least justify my actions)?

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.

OpenSUSE Install :: User 'root' Can Read The Content Of The File

Apr 12, 2011

I came across this issue today and it changes everything I know about file permissions in linux. I created the following files in my system :

Code:

/tmp> ls -lad /tmp/testperm/
drwx------ 2 sagi users 4096 Apr 12 20:23 /tmp/testperm/
/tmp> ls -lad /tmp/testperm/file.txt
-rw------- 1 sagi users 12 Apr 12 20:23 /tmp/testperm/file.txt

[code]....

One more thing, as you can see I also set that only the owner of the directory (which is me again) can read and cd (the execute bit) to the directory. how come user 'root' can read the content of the file ?

Code:

# id
uid=0(root) gid=0(root) groups=0(root)
# cat /tmp/testperm/file.txt
Hello world

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.
