Having trouble listing the contents of a folder I'm not in, while excluding the actual folder name itself.
ex:
root#vps [~]# find ~/test -type d
/root/test
/root/test/test1
However I want it to only display /test1, as the example.
Thoughts?
There's nothing wrong with a simple
find ~/test -mindepth 1
Similarly, this will have the same effect:
find ~/test/*
as it matches everything contained within ~/test/ but not ~/test itself.
As an aside, you'll almost certainly find that find will complain about the -mindepth n option being after any other switches, as ordering is normally important but the -(min|max)depth n switches affect overall behaviour.
You can do that with -exec and basename:
find ~/test -type d -exec basename {} \;
Explanation:
The find ~/test -type d part finds all directories recursively under ~/test, as you already know.
The -exec basename {} \; part runs the basename command on {}, which is where all the results from the last step are substituted into.
Then you need -type f instead of -type d.
Or, if you want to display list of folders, excluding the parent -mindepth 1 (find ~/test -type d -mindepth 1).
And now that you edited it, I think what you want may be
find ~/test -type d -mindepth 1 |cut -d/ -f3-
But I think you need to be more specific ;-)
I just fixed it with sed
find $BASE -type d \( ! -iname "." \)|sed s/$BASE//g
Where $BASE is initial foldername.

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.
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.
I have a dir that is full of many htm reports that I keep around for 30 days and delete old ones via a cron, but there is one sub-dir I would like to keep longer. So this is the line I made in the cron, but how do I tell it to leave one sub-dir alone.
5 0 * * * find /var/www -name "*.htm*" -type f -mtime +30 -exec rm -f {} \;
Any help is greatly appreciated!
Use -prune to prevent going into a directory that matches some conditions.
find /var/www -type d -name 'excluded-directory' -prune -o -name "*.htm*" -type f -mtime +30 -exec rm -f {} \;
In addition to suggestion below, suggesting to use full path in cron.
Also to use find option -delete in-place of -exec rm -f {} \;. It is somewhat safer.
-delete
Delete found files and/or directories. Always returns true.
This executes from the current working directory as find recurses
down the tree. It will not attempt to delete a filename with a
"/" character in its pathname relative to "." for security
reasons. Depth-first traversal processing is implied by this
option. The -delete primary will fail to delete a directory if
it is not empty. Following symlinks is incompatible with this
option.
5 0 * * * /usr/bin/find /var/www -type d -name 'excluded-directory' -prune -o -name "*.htm*" -type f -mtime +30 -delete
I'm on a linux system I wonder what is wrong with the following execution of find:
mkdir a && touch a/b
find . -name a -type d -exec echo '{}' \;
./a
find . -name a -type d -exec rm -r '{}' \;
find: `./a': No such file or directory
The invocation of echo is just for testing purposes. I would expect the last command to remove the directory './a' entirely and return 0. Instead it removes the directory and generates the error message. To repeat, it does remove the directory! What is going on?
rm executes without a problem. The issue is that find is confused, since it knew the directory ./a was there, it tries to visit that directory to look for directories named a. However, find cannot enter the directory, since it was already removed.
One way to avoid this is to do
find -name a -type d | xargs rm -r
This will let the find move along before the rm command is executed. Or, you can simply ignore the error in your original command.
Based on epsalon's comment the solution is to use the -depth option which causes the deeper files to be visited first.
find . -depth -name a -type d -exec rm -r '{}' \;
does the trick. Thanks a bunch!
If performance is an issue, use -prune in order to prevent find from descending into directories named "a":
find . -name a -type d -prune -exec rm -r '{}' \;
How do I get the name of a folder from a linux find commnad.
I have a command like this:
find /root/wgetlog -name -type d -empty
Whic produces the following results:
/root/wgetlog/smil3
/root/wgetlog/smil5
/root/wgetlog/smil4
how do I get just the name of the folder:
Example:
smil3
smil4
smil5
find /root/wgetlog -type d -empty -printf "%f\n"
If all you need is a relative path, then
{ pushd /root/wgetlog/; find . -name -type d -empty; popd; }
is the approach, especially if you do care about subdirectories of /root/wgetlog/*.
Use basename:
find /root/wgetlog -type d -empty -exec basename {} \;
You don't need -name.
You could also use sed to filter out the leading elements of each path:
$ find /usr/bin -type d
/usr/bin
/usr/bin/multiarch-i386-linux
/usr/bin/multiarch-x86_64-linux
/usr/bin/gda_trml2pdf
/usr/bin/gda_trml2html
...
$ find /usr/bin -type d | sed 's|.*/||'
bin
multiarch-i386-linux
multiarch-x86_64-linux
gda_trml2pdf
gda_trml2html
...
This might be more portable than using the -printf option of find, although that should not be an issue if you stick to Linux.
Disclaimer: this will fail horribly if you have newlines in your file/folder names. On the other hand, this snippet is probably not the only thing that would fail in that case...
