View 1 Replies View RelatedI'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?
View 4 Replies View RelatedMy 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 Iïve 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.
I wanted to copy one file to multiple new files. I have an idea to write a script and do the operation. But here i m looking for any particular command to do this operation.

I had a working scripted last night, deleted it by mistake and for the life of me can not remember how i did it.
I've got a text file with a list of .gz files, these .gz files are in various sub directories of one parent directory and I've hacked this little script together to copy them from their current location to a new one and spit out any it can't find to "/home/user/not_found" but for the life of me can't get it to run properly!

I am using find to search for .tgz files modified more than 7 days ago and delete them.find /directory/ -iname backup*.tgz -daystart -mtime +7 -exec rm -rf {} My problem is that find will go through the content of tarball as well and list all content. I want to only search main tarball and delete it if older than 7 days.

I'm just starting out with shell-scripting, but having a problem with making new text files with the touch or cat > commands.
What I've been doing is touch testfile1.txt
Also, I've tried cat > testfile1.txt (text)
Console reports "bash: text1.txt: No such file or directory. Consfusingly, it works fine in the home-directory. But if I move the file to where I want it, I can no longer view, edit, etc. it.
I need to be able to compare a file date with system date and delete files older than 30 days.
the file name is basically
error_log.03222011
of course the extension is the date the file was created.
Oh and before i get hammered I looked everywhere but am unable to make sense of what I found.
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.

I can echo the file using:
