I am trying to find all empty directory using find command and also using alpinelinux , but unfortunately we don't have any option of action as empty in alpine. Anyone have any suggestion on how can achieve this.
I am trying to use below
find . -depth -type d -empty -mmin +120 -print;
Anyone can suggest if any package/library can solve this issue .
You may google how to check empty dir in shell and execute a subshell for each directory and make the subshell exit with zero exit status if the directory is empty:
find . -depth -type d -exec sh -c '[ -z "$(ls -A "$1")" ]' _ {} \; -print
Other then that, install GNU find.

I have these files in my source folder
source_path/date=20191230/somefile.txt
source_path/date=20191231/somefile.txt
source_path/date=20200101/somefile.txt
source_path/date=20200102/somefile.txt
If I do the bellow command all files will be copied to my dest_path folder
cp --recursive source_path/ dest_path/
I just want to copy all folders where dates are in 2020 or something
I just need these to files of 2020
source_path/date=20200101/somefile.txt
source_path/date=20200102/somefile.txt
How can I add filters with cp command
This question is not suitable for Stack Overflow, but this is the answer:
cp --recursive source_path/date=20200* dest_path/
Or does dest_path not exist? Then you would write
mkdir -p dest_path && cp --recursive source_path/date=20200* dest_path/
You can use find with the -name, -type and -exec flags and so if the source directory was /home/foo and the destination directory /tmp:
find /home/foo -type d -name "*date-2020*" -exec cp '{}' /tmp \;
-type signifies that we only searching directories, -name is the name we are searching for and exec for command we are executing with the results

In Bash it is possible to
ls [G-S]*
and it would list all files from g-s and G-S.
How is that done in Fish shell?
Fish currently does not support a rich glob syntax. The current thinking is that a glob command should be added in keeping with the fish goal of doing things via commands rather than magic syntax. See, for example, https://github.com/fish-shell/fish-shell/issues/3681. The solution is to create a function that filters the results. For example, the ** glob matches all files and directories in and below the CWD. I frequently want just the plain files and want to ignore the .git subdir. So I wrote this function:
function ff --description 'Like ** but only returns plain files.'
# This also ignores .git directories.
find . \( -name .git -type d -prune \) -o -type f | sed -n -e '/\/\.git$/n' -e 's/^\.\///p'
end
Which I can then use like this: grep something (ff). You could create a similar function that uses the find -name pattern matching feature or filter the results with string match --regex.
You can use find -iregex "./[G-S].*". Fish is quite limited in this regard.

I've created script which delete old backup file from directory but this command was worked fine before 1 week and Nothing change on script or packages but still getting below error:
root#:# find /var/backups/abc/* -type d -mtime +6
/var/backups/abc/2016-03-09_0321
root#:~# find /var/backups/abc/* -type d -mtime +6 -exec rm -rf {} \;
find: `/var/backups/abc/2016-03-08_0321': No such file or directory
Problem is that, this script run every day on cron, I getting a mail like " find: `/var/backups/abc/2016-03-08_0321': No such file or directory". files are deleted but such a mails are getting from root.
find /var/backups/abc/* -type d -mtime +6 -prune -exec rm -rf {} \;
Here, we use -prune on the directories that we're about to delete, so find will then not try to read their contents.
This is because of after having returned your directory, find will try to look in it (to continue his recursive search), and will fail because of you just removed it.

Can someone with more Linux knowledge answer this correctly for me.
On our web server, we host and run ALOT of web scripts.
we control these via Datestamp files, So the script is not over ran, or ran more than once.
A lot of files are all 0 KB. I wanted to know if there is a quick way in Linux to locate the files and update them.
I have located the files using:
find /var/www/vhosts/DOMAINNAME.co.uk/httpdocs -name "datestamp.*" -type f -empty
I have a long list of files, Can i update these with a simple datestamp format:
i.e.
20150923114046
You can use the -exec option of find:
find /var/www/vhosts/DOMAINNAME.co.uk/httpdocs -name "datestamp.*" -type f -empty \
-exec bash -c 'echo 20150923114046 > {}' \;
To get the timestamp dynamically, use date:
bash -c 'echo $(date +%Y%m%d%H%M%S) > {}'
To use the last modified timestamp, use the -r option:
bash -c 'echo $(date +%Y%m%d%H%M%S -r {}) > {}'

Remember I need the command to change permissions of all files in current folder?
It depends on what you mean by "current" folder; if you mean the current folder (and all subfolders) then you could use find and chmod like so -
find . -type 'f' -exec chmod +x {} \;
If you mean the current folder (and no sub-folders) then you would use it like so -
find . -maxdepth 1 -type 'f' -exec chmod +x {} \;
OR you could use find (possibly with maxdepth) and xargs likes so
find . -print0 | xargs -0 chmod +x
Note that these commands will correctly handle files with spaces in the name and most other edge cases.
Use chmod with a glob:
chmod +x *
(Technically that will give permission to list directories, too, but that shouldn't be a problem.)
