Is there a bash command that I can use to determine the last file access time? I know about -atime option for the find command, but I want to doublecheck to make sure that I'm doing this correctly (the output when I use find -atime isn't what I expect).
View 4 RepliesI am trying to modify the file access time in a Python routine I have. I have I believe the correct code for this but have a greater issue. Looking at a random file in my home directory I can see it was last accessed yesterday (I didn't open this file yesterday) so it was presumably my virus scan. No problem there Now I have opened the file today,rescanned the file for viruses and read the file in Python and the file access time remains the same!I have checked the access time by right clicking on the file and choosing Properties, using "ls -lu", and using os.stat(path) in Python.

I am writting a script to allow uploading of certain files. I want to limit the files by their filename and mime type, and by making sure the two match up.The first thing I need to do is make sure I've got all the mime types I need added. I have never done this before, but I understand that 'file' (which is what PHP's mime-type finding is based off of) uses magic databases that tell at which point in the file should have signatures of the filetype.
My trouble started when I was unable to determine the filetype of any of my video files. Currently, I have some .MOV and .MP4 files that I am using to test.
I see from the netspeed applet that my computer is downloading stuff almost constantly. Not a whole lot, 8b - 700b per second while apparently doing nothing. Some of this is just responding to broadcasts from the router, but surely not all. I would like to be able to determine which programs are accessing the internet over that wireless card, with a view to cutting down on my bandwidth usage. Is there a program that can tell me which ones are doing what at a given time?

I say ~98% accurate since ID3 tags do consume a small amount of space.

I am writing, well actually enhancing, a script to do a daily backup of important data on my PC to a second hard drive.I wish to tar my home directory to a single file - and will probably use gzip as well.So I decided to work out the correct tar syntax in a terminal first - here is what happened.I opened a terminal window.I cd to a directory not part of my home directory.I issued the command..Quote: tar -cvf mytar.tar /home/ken tar processed a bunch of files, the last being .netrc.I examined the tar file and it contains .netrc.The contents of .netrc are correct.I scrolled back through the list of files in the terminal window and do not see any error messages.I guess the question is... how do I determine what file tripped up the tar process?
View 8 Replies View RelatedI have the following which works but think there must be a easier one-liner way of doing this which involves not writing to a file but have failed to find something that works This is what I have:
Code:
du -m $i > filesize.txt
FILESIZE=$`cat "filesize.txt" | cut -f1
rm filesize.txt
I then use the FILESIZE to compare to a number.

### TO DO: Determine the report file name based on the source directory name and current date### The report name and thumbnail directory must follow this pattern: source-%j-%H### for example, for pictures in /home/you/pictures, the file name will be: pictures-%j-%H### HINT: Use sed to extract the directory name from the path and combine it with date command output

I would also like to be able to password protect this if possible.So for instance, from 7am until 10pm daily, I can access URL... but after 10pm it redirects to 127.0.0.1 or something. And this configuration be protected by only allowing a certain user (other than root) to change the config?
View 7 Replies View RelatedI managed to install a second hand 10Gb HDD on my old P4. I want to see how I can use this extra disk to speed up Ubuntu 10.04 if possible.
I installed my swap onto this second drive but since I never use swap I can't see any real improvement. Next, I'm considering the creation of a new partition on that disk that would handle /tmp. Could that improve access times?
Finally, what other tricks could I use with this 2nd HDD to speed things up?

View 1 Replies View RelatedI need to get the modified date on a file in linux to use in a script.I tried using 'ls -l' on the file, but this caused problems when the date turned from a single digit into a double. The reason for the problem was because I was parsing the result string on spaces.How can I get the date of the last time a file was modified so I can use it in a script? For example, if a file was modified on 1/11/2010, I need the 11.
View 2 Replies View RelatedI am using cygwin in order to test a bash script that uses the ls -R command. When I use this, the access date of the subfolders are changed, and I need them to remain what they were before the command was run. I don't have access to a legitimate Linux system, so I'm not sure if this is the fault of cygwin or the ls command. The script is being used to find the last access date of all files underneath several subfolders and then return the latest date found in each subfolder as the last access date for that subfolder. For some reason, some of these folders have files in them that are newer than the folder's last access date, so the script is meant to give us a list of the true last access date for these folders.

- More info :I have found that by unmounting in nautilus and then remounting, I can get write access again. I believe this might be the cause of the ipod application floola, although I will do some more troubleshooting and see what else I can find out.
