How To Delete Number Of Files

I need to clean-up some folder. I have a cron job which uses find command to find and delete 25 days older file.

Code:

find $FOLDER_PATH/$FOLDER -depth -regex  ^$FOLDER_PATH/$FOLDER/[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$ -type d -mtime +25  -exec ls -ld {} \;   >> /tmp/deleted_folders.log

When this running it occupies 1-3% of cpu. And it may take longer time based on the folder size.

Is it ok to have find command running as cron job ?

Hi,

I'm wondering if anyone can help me make a script that searches through a specific folder (in this case /tmp ) for files with a given permissions (755) and then delete all the other files with different permissions?

The correct permission should be, as mentioned 755, and those are the files that should be kept (not deleted).
All other files in this folder with different permissions should be deleted.

Thanks!

Hi

I have a folder :

Code:

/usr/local/src/myfolder

and i have there a few folders and files ...

Now i want to delete from this folder the files named:

Code:

file1.txt 
image.jpg
info.html
another.txt

and leave all the rest folders and files...

How is the correct syntax for this?

If it is possible to not use cd /usr/local/src/myfolder and then rm -r .... so i can run it from everywhere ....

Thanks

Hi all,

I'm trying to identify files that do not have matches for certain strings. FYI, these are files of DNA sequences and I'm trying to find those that are NOT sampled for any species by my group of interest (e.g., genes that are specific to that group of organisms).

I tried this code but it's actually yielding a list of files that DO match for my regexp.
Code:

for FILENAME in *.fas
do
grep -q -L ">PBAH" $FILENAME && grep -q -L ">SKOW" $FILENAME && grep -q -L ">CGRA" $FILENAME && echo $FILENAME
done

Basically I want to somehow go through and file files that do not contain ">PBAH" ">SKOW" or ">CGRA". Any assistance would be greatly appreciated!

Best,
Kevin

Hi,

I created a user and when i logged in it took me to the $>
I was reading online and i stumbled with this command
cp -r /etc/skel/.* etc/skel/*
I was stupid enough to copy it
Now our home folder is full of files and my boss is not happy.

Is there a reverse to this command? or Can I just delete the files been copied?

Thanks

Hey, I'm aware that /etc/ stores config files and in my home directory I also have dot files as well as a .config folder.

And I'm told not to edit /etc/ but create a copy in my home directory to preserve original files. Is it as simple as creating the full path the same as /etc/ and editing it in home folder?

Ideally this is how I hope it works, because I don't want to edit /etc/ and end up with a bunch of custom, non default files.

Hello,

I am new to Linux images (pxe, livecd). I would like to add files to a linux image, like something under etc or var, and have the files be available on the client.
The server I am working on was already configured with a pxe image, and only 2 files are present under the pxe client folder: initrd and vmlinuz. So I am wondering if either of these files contain the dirs /etc, /var, etc..., and how I could add files to them.

To give some background, I have done the same thing in Windows. An image in Windows is typically either boot.img or install.img. You can mount either of these to a folder using the Windows SDK tool imagex.exe /mountrw <img file> 1 <mount point>. From here you can add/remove/modify any files you want. Then commit the changes with imagex.exe /unmount <mountpoint> /commit.

Can someone provide insight to the linux image creation process, which of the files (initrd, vmlinuz/vmlinux, etc...) contain what for the client boot, or something similar to the Windows Image editing process?

I know I'm asking for a range of info, but pointers to any material to help my understanding will be greatly appreciated.

Thanks,
Jon

Some weeks ago I installed Linux Mint 17.1 Cinamin. Yesterday I installed 17.1 KDE. Now I have an home directory with empty set of user folders. I did find all of my files under devices 129.0 GiB Hard drive, including the old Home folder. How do I get my old files back to where I can use them?

I'm running Xubuntu and it was a challenge just getting Copy.com on there. (I installed the desktop app on both of my computers.) Now that I have it though, I don't really know how to use it.

I know this is kind of more a Copy.com question, but I don't know anything about Copy.com (besides having it--lol) and besides, I like you LQ guys.

So yeah, I installed the desktop app for Copy.com on both of my computers. I know that if I put something in the Copy folder that will be available to both computers.

But how Copy does the backing up I don't know.

When I change a file or folder do I have to plop that into the Copy folder every time or does Copy somehow update the file or folder in the Copy folder automatically? (It doesn't seem to.)

Okay, when I, say, take the Documents folder from one computer and plop it into the Copy folder that's that. Then I take the Documents folder from the other computer and plop that into the Copy folder, then all the files from both folders will be in the Copy folder (and the Copy cloud), right?

Now I just removed a couple of files from a folder and copied and pasted the folder into the Copy folder. But then when I looked at the Copy folder the files I'd deleted were still there. What's the process? How does it work?

I mean, how does this work as a way of backing things up AND organizing things? To me it seems like a decent way of throwing stuff into the Copy folder (and cloud), but how is that different than Google Drive? I mean, that's not really a backup, is it? It's like a flash drive in the cloud.

And when I combined the same folders (with the same titles anyway, but they each had different files within them) from the two computers I'd expected each folder on each computer to have all the same files that were cumulatively on both. Instead, they're the same. And the cumulative is only on the Copy folder.

I like the notion of just throwing the folders and files into the Copy folder. It's much quicker than Google Drive. But the backing up feature eludes me and the syncing feature makes me fearful that I'll lose data or that the files will become hopelessly less organized.

Thanks.

Hello Folks.

I'm searching for a easy way to rename multiple files from CLI but didn't find any easy way for me so I'm reaching out to you guys for help.

This is what I want to do (from CLII or script). I want to move files with a sequence number on the name of the files (msg0000, msg0001, msg0002 and so on) to let's say msg0066, msg0067 and so on. Each of this file name has two other files (msg0000.wav, msg0000.WAV and msg0000.txt).

The idea is to move them from one directory to another and following a sequence in the file names, is there a way I can do this pain free?

Any help on this matter will be greatly appreciates and I'm talking about over 100 files I need to move following the sequence of the receiving directory.

Thanks!
