Programming :: Search A Bunch Of Files In A Specific Folder For A Specific Number?
Jul 24, 2010
I need to search a bunch of files in a specific folder for a specific number and add all the numbers together to a total sum. I use Rsync everyday, everytime I run rsync i get a logfile (rsync output) witch contains the textstring "Total bytes sent: xxxxxx".
The "xxxxx" can vary in lenght. I need to extract the "xxxxxx" from each file and add the numbers together to a total size over a week or a month. Is this possible? And I wish to only use bash. One way of doing stuff at a time my friends .
I want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ; [1] 5052 useratdebian:/home/user/folder# find: missing argument to `-exec' [1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?
I have a script that checks a folder for zip files than moves them to a different folder. I want to check every 5 maybe 10 seconds and since cron is setup to run at least a 1 minute increment I'm not sure how to do that time check as probably a loop within the script. One other thing is once the time check is in the script how would a cron job be setup to run this script? Once the script is running cron doesn't need to run it again, is there a feature to check if it's running and if it's not then run it?
Is there an app or find parameter that can search for video files using a specific (DivX for example) encoding? On Windows, you can do this, so I was hoping there would be some way on Linux whether it's with find or another app. I want to find all (*.avi OR *.divx) on my file system with the DiVX fourcc tag (i think that's what its called)
how to search for a specific string of text inside an html document. I then want to cut out that specific data that the field or string contains. I want to do a shellscript that makes this function automaticly.
For example:
# #Here i want to find the field "town" inside the html/java and then cut #out the town name from it and paste that to an file. # #
I am trying to create a socket to listen for a bootp response so I am using a PF_PACKET socket so that I get the response based on my mac. My problem is that I don't want to hear all traffic (as I do now) so would like to use a specific port number and bind to it.
i want such a shell script or single line command to delete all the files with extension specified in script i have bash !! ex... delete all files of extension .obj
I would like to parse an input file in which there are two columns per each row. We want to see how many lines are duplicated where we define duplicate to be having the same second field and different first field. For instance if the input file looks like the following:
sudo cp ../../../rootfs_maker_ramdisk drivers/filesystem/ -rf give below errorCode:cp: cannot create special file ...._rootfs/dev/hda4': No such device or addressi get this error only in some specific locationsif i dont use sudo then i get permission denied msg
I am trying to use the command gzip to compress a directory or file list as argument and compress the file in a file named copia101225, within a directory named ZIPFILES. I want to make sure that if the arguments doesn't exist, the destination directory doesn't exist that it creates it. I keep failing at compressing the file to copia101225, that is within the directory named ZIPFILES This is what I have so far:
#! / bin / bash # Title: Compress a file # Author: Jose Miguel Colella # Description: Compress a file
What would be the best way to automatically copy all of the data off of a library of cds to a specific folder on the computer? I was thinking of running a bash script but I've run into a few snags figuring out the correct way to do it. Mainly due to the fact that the cd drive is mounted in a different folder in /media each time I insert a new diskAlso, the mounting and unmounting process causes it's own problems, but I think that could be covered by a for loop that checks /mtab every few seconds or so.
When I try to upload files via FTP to a specific folder (/var/www/myfolder/) I get the message 550 permission is denied. I set CHMOD 777 for this folder (I had to do this via SSH cause I was not allowed to do this in FileZilla)
I am using secure delete to remove files from a Debian Linux PC. However, secure delete does not remove folders. This has lead me to look at writing a script that would move files to a predetermined folder for deletion. My plan is as follows:I have a folder on my desktop called shredder where I move the contents of the waste bin to. The script needs to identify all files within the folders and sub folders, within the shredder folder, and move each file to the shredder folder and then delete the folder. At this point secure delete can be used with a command like shred -v -u *.*on the shredder folder.The problem I have is in creating the code to move files from the different folders and then deleting the folders. Note that the names of the files, folders and subfolders will not always be known
app deployment on Linux/debian and I'm using Debreate to create .deb packages which works fine. I install the software itself to /usr/bin but want to install the program's database to /home/username/myapp/ The problem is it that I don't know how to add the env variable 'username' to the target path. What is the exact syntax for this installation path?
Terribly new to Linux and find it mindboggling. I work on brain imaging and unfortunately all of the analysis runs on Linux, and I do not understand computers well coming as I do from a medical background. So my question - There are various folders of patient MRI scans (folders called P1, P2, P3 etc) and within them are enclosed certain files that I am interested in (always called the same name in all folders, say image001). I would like a script that enables me to copy and move this image001 in all these individual folders to another folder altogether.
I need a command to find the all files which filename contains the text "SomeText" and to delete that files!From /home/movie/wp-content/uploads/this folder I have lots of files and folders .Also I need that for folders and subfolders who contains some text in folder name "someTextInFolderName"
how the "-prune" option works. I've searched quite a bit on line, and as far as I can tell, "-prune" works exactly the opposite as it says.
I'm using Apt-proxy, and I want to scan through the folders, and find files that end with "*.bz2" The problem is that the search takes a while because of all the "*.deb" files. Fortunately, they're stored in their own folder:
/var/cache/apt-proxy/ubuntu /var/cache/apt-proxy/ubuntu-security /var/cache/apt-proxy/partner each have two folders:
Is it possible to setup SSH Daemon to listen on multiple ports and only accept specific groups to a given port? In the past I've created a second SSH Daemon by copying the config file and /etc/init.d/ daemon then configuring each port separately / rules however if I was able to maintain just the one Daemon that would be optimal. Is this possible?
I've figured out that '~i !~M' will give me all packages I have manually installed. Can I formulate a query such that I get all packages manually installed from a particular distribution (e.g. Lenny, Squeeze, Sid)? Yes, I'm using pinning.
How do you find a file modified March 17, 2010, between 3:30 pm and 4:05 pm? I know that I must be missing something somewhere.How do you search for info like this? I goggled "search files time Linux" and got about 38,300,000 results. I looked through the first four pages and did not see what I was looking for.Do I need to calculate how many minutes ago that is and give that to find.I really want to do this in the GUI so that I can operate on the files found without typing in so much stuff.
If i am in the root directory and i need to search for a specific file in the sysconfig directory, is there any way to search this directory for a file?
How do I give permission to a logged in user to stop/start a specific service without entering a root/sudo password? So they can do a simple "service SomeService stop|start" It is for a headless Ubuntu server.
