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 RelatedI have ubuntu server 10.4 installed on an Intel SS4200-E, which I have configured without any RAID. This machine acts as a media server to another PC. The other PC runs Windows 7 Ultimate. I have 3 1TB hard disks connected to it, and the file system on all the 3 are NTFS. I have mounted the hard disks as ntfs. I have made the folders on all the 3 hard disks shareable. I have configured Samba to make the folders on the hard disks "visible".
The ubuntu machine is in a headless configuration (it doesn't have any VGA card where can connect a monitor). I can configured SSH on it, so I can use putty from the Windows machine to logon to the ubuntu machine, but it is text based only. I am able to see all the 3 disks from the Windows machine. I am able to read/write into 2 of the disks. I am able to read, copy and delete from the 3rd disk, but not write new content to it.
Following is the snippet from /etc/fstab:
Code:
/dev/sda3 /media/Media1 ntfs-3g defaults,locale=en_US.utf8 0 0
/dev/sdb1 /media/Media2 ntfs-3g defaults,locale=en_US.utf8 0 0
/dev/sdc1 /media/Media3 ntfs-3g defaults,locale=en_US.utf8 0 0
Following are the lines which I have added to the end of /etc/samba/smb.conf:
Code:
[Media1]
path = /media/Media1
writable = yes
guest ok = yes

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

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)?

View 1 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.
