Delete old files using ls and find command - linux

My folder structer looks like below:
folder1
---tmp
---sub1
folder2
---tmp
---sub2
folder3
---tmp
---sub3
folder4
---tmp
---sub4
I want to delete files which older than 30 days in all tmp folder.
list all tmp folder:
ls -d */tmp
delete all files which older than 30 days
find . -mtime +30 -type f -delete
Could i combine these 2 steps into one command line?

What you can do is replace the . in your find with the actual directories you want to search in.
find */tmp -mtime +30 -type f -delete
If tmp can be several levels deeper then you might be interested in
find . -regex '.*/tmp/[^/]+' -mtime +30 -type f -delete
or similar to the first option, but by using the double-star globular expression (enabled with shopt -s globstar)
find **/tmp -mtime +30 -type f -delete
* Matches any string, including the null string. When the globstar shell option is enabled, and * is used in a pathname expansion context, two adjacent *s used as a single pattern will match all files and zero or more directories and subdirectories. If followed by a /, two adjacent *s will match only directories and subdirectories.
source: man bash
Note: you have to be careful though. Imagine that you have a directory folder1/tmp/foo/ then the above commands (with exception of the regex version) will select also files in folder1/tmp/foo and this might not be wanted. You might be interested in the extra option -maxdepth 1

Linux deleteing a folder's content

I can find ./ -type d -name "Debug" -exec rm -f {} + to delete the fold and content.
My question is: How to fine all "Debug" folders and ONLY delete the content and Not the folder?
#!/bin/bash
find . -type d -name "Debug" -print | xargs -I% find % -maxdepth 1 -type f -delete
the first find lists all Debug directories
xargs defines the "%" symbol as what is replaced by the received stdin. You will often see -I{} for xargs, but I chose another string since you might need {} in the find. Any char will do.
the second find, in directory "%" (so here one of the Debug directories received from the first find), deletes all files under that directory.
-maxdepth 1 is used in the second find to make sure it only deletes the files in the current Debug directory, and does not recursively deletes all files.

how to move jpg and jpeg files whose size is greater than 10kb [duplicate]

I have some automated downloads in a proprietary linux distro.
They go to a temp scratch disk. I want to move them when they're finished to the main RAID array. The best way I can see to do this is to check the folders on the disk to see if the contents have changed in the last minute. If not then its probably finished downloading and then move it.
Assuming there could be hundreds of folders or just one in this location and its all going to the same place. Whats the best way to write this?
I can get a list of folder sizes with
du -h directory/name
The folders can contain multiple files anywhere from 1.5mb to 10GB
Temp Loc: /volume2/4TBScratch/Processing
Dest Loc when complete: /volume1/S/00 Landing
EDIT:
Using this:
find /volume2/4TBScratch/Processing -mindepth 1 -type d -not -mmin +10 -exec mv "{}" "/volume1/S/00 Landing" \;
find: `/volume2/4TBScratch/Processing/test': No such file or directory
4.3#
yet it DOES copy the relevant folders and all files. But the error worries me that something might go wrong in the future.... is it because there is multiple files and it's running the same move command for EACH file or folder in the root folder? But since it moves it all on the first iteration it cant find it on the next ones?
EDIT2:
Using Rsync
4.3# find /volume2/4TBScratch/Processing -mindepth 1 -type d -not -mmin +10 -exec rsync --remove-source-files "{}" "/volume1/S/00 Landing" \;
skipping directory newtest
skipping directory erw
RESOLVED: EDIT3
Resolved with the help in the comments below. Final script looks like this:
find /volume2/4TBScratch/Processing -mindepth 1 -type d -not -mmin +10 -exec rsync -a --remove-source-files "{}" "/volume1/S/00 Landing" \;
find /volume2/4TBScratch/Processing -depth -type d -empty -delete
rsync to move folders and files but leaves empty root dir
the next command finds empty folders and removes them.
Thanks all!
You can use GNU find with options -size for detecting files/folders of certain size and use mv with the -exec option to move to destination directory. The syntax is
find /volume2/4TBScratch/Processing -type d -maxdepth 1 -size -10G -exec mv "{}" "/volume1/S/00 Landing" \;
Using rsync
find /volume2/4TBScratch/Processing -type d -maxdepth 1 -size -10G -exec rsync --remove-source-files "{}" "/volume1/S/00 Landing" \;
The size with a - sign to indicate less than the mentioned size which in this case is 10GB. A note on each of the flags used
-type d -> For identifying only the folders from the source path.
-maxdepth 1 -> To look only on the current source directory and not
being recursive.
-exec -> Execute command following it.
Alternatively, if you want to find files that are last modified over a certain time(minutes), find has an option for -mmin which can be set to a value. E.g. -mmin -5 would return files modified five minutes ago.
So suggest adding it to your requirement, for x as you need and see if the directories are listed, then you can add the -exec option for moving the directories
find /volume2/4TBScratch/Processing -type d -maxdepth 1 -mmin -2 -size -10G
Refer to the GNU documentation for finding files according to size on how this works.
Note:- The double quotes("") are added to avoid Bash from splitting the names containing spaces.

How to delete files and directories older than n days in linux

I have a directory named repository which has a number of files and sub directories. I want to find the files and directories which have not been modified since last 14 days so that I can delete those files and directories.
I have wrote this script but it is giving the directory name only
#!/bin/sh
M2_REPO=/var/lib/jenkins/.m2/repository
echo $M2_REPO
OLDFILES=/var/lib/jenkins/.m2/repository/deleted_artifacts.txt
AGE=14
find "${M2_REPO}" -name '*' -atime +${AGE} -exec dirname {} \; >> ${OLDFILES}
find /path/to/files* -mtime +5 -exec rm {} \;
Note that there are spaces between rm, {}, and \;
Explanation
The first argument is the path to the files. This can be a path, a directory, or a wildcard as in the example above. I would recommend using the full path, and make sure that you run the command without the exec rm to make sure you are getting the right results.
The second argument, -mtime, is used to specify the number of days old that the file is. If you enter +5, it will find files older than 5 days.
The third argument, -exec, allows you to pass in a command such as rm. The {} \; at the end is required to end the command.
This should work on Ubuntu, Suse, Redhat, or pretty much any version of linux.
You can give the find -delete flag to remove the files with it. Just be careful to put it in the end of the command so that the time filter is applied first.
You can first just list the files that the command finds:
find "${M2_REPO}" -depth -mtime +${AGE} -print
The -d flag makes the find do the search depth-first, which is implied by the -deletecommand.
If you like the results, change the print to delete:
find "${M2_REPO}" -mtime +${AGE} -delete
I know this is a very old question but FWIW I solved the problem in two steps, first find and delete files older than N days, then find and delete empty directories. I tried doing both in one step but the delete operation updates the modification time on the file's parent directory, and then the (empty) directory does not match the -mtime criteria any more! Here's the solution with shell variables:
age=14
dir="/tmp/dirty"
find "$dir" -mtime "+$age" -delete && find "$dir" -type d -empty -delete

Bash Command for Finding the size of all files with particular filetype in a directory in ubuntu

I have a folder which contains several file types say .html,.php,.txt etc.. and it has sub folders also .Sub folders may contain all the file types mentioned above.
Question1:- I want to find size of all the files having the file type as '.html' which are there in both root directory and in sub- directories
Question2:- I want to find size of all the files having the file type as '.html' which are there only in root directory but not in sub folders.
I surfed through the internet but all i am able to get is commands like df -h, du -sh etc..
Are there any bash commands for the above questions? Any bash scripts?
You can use the find command for that.
#### Find the files recursively
find . -type f -iname "*.html"
#### Find the files on the r
find . -type f -maxdepth 1 -iname "*.iml"
Then, in order to get their size, you can use the -exec option like this:
find . -type f -iname "*.html" -exec ls -lha {} \;
And if you really only need the file size (I mean, without all the other stuff that ls prints):
find . -type f -iname "*.html" -exec stat -c "%s" {} \;
Explanation:
iname search of files without being case sensitive
maxdepth travels subdirectories recursively up to the specify level (1 means only the immediate folder)
exec executes an arbitrary command using the found paths, where "{}" represents the path of the file
type indicates the type of file (a directory is a file in Linux)

How to delete all files older than 3 days when "Argument list too long"?

I've got a log file directory that has 82000 files and directories in it (about half and half).
I need to delete all the file and directories which are older than 3 days.
In a directory that has 37000 files in it, I was able to do this with:
find * -mtime +3 -exec rm {} \;
But with 82000 files/directories, I get the error:
/usr/bin/find: Argument list too long
How can I get around this error so that I can delete all files/directories that are older than 3 days?
To delete all files and directories within the current directory:
find . -mtime +3 | xargs rm -Rf
Or alternatively, more in line with the OP's original command:
find . -mtime +3 -exec rm -Rf -- {} \;
Can also use:
find . -mindepth 1 -mtime +3 -delete
To not delete target directory
Another solution for the original question, esp. useful if you want to remove only SOME of the older files in a folder, would be smth like this:
find . -name "*.sess" -mtime +100
and so on.. Quotes block shell wildcards, thus allowing you to "find" millions of files :)
