I want to run a find command but only find the files in directories, not the directories or subdirectories themselves. Also acceptable would be to find the directories but grep them out or something similar, still listing the files in those directories. As of right now, to find all files changed in the last day in the working directory, and grep'ing out DS_Store and replacing spaces with underscores:
find . -mtime -1 -type f -print | grep -v '\.DS_Store' | awk '{gsub(/ /,"_")}; 1'
Any help would be appreciated!
If you have GNU find:
find . -mtime -1 ! -name '.DS_Store' -type f -printf '%f\n'
will print only the basename of the file.
For other versions of find:
find . -mtime -1 ! -name '.DS_Store' -type f -exec basename {} \;
you could then do:
find -name index.html -exec sh -c 'basename "$1" | tr " " _' _ {} \;

I need a script that removes all empty files and writes a list of deleted files to a text file.
Deleting files works. Unfortunately, the listing does not work.
find . -type f -empty -print -delete
I tried something like this:
-print >> test.txt
When I redirect the output of your command to a file in ., it gets delete by the find command before anything is written to it, since it is empty.
To solve this, make sure the output file is not empty at the beginning, or save it elsewhere:
find . -type f -empty -print -delete > ../log
or
date > log
find . -type f -empty -print -delete >> log
or, adapted from #DanielFarrell's comment:
find . -type f -empty -a -not -wholename ./log -print -delete > log
The added -a -not -wholename ./log excludes ./log from the find operation.
You can use -exec option with rm command instead of -delete.
find . -type f -emtpy -exec rm --verbose {} \; >> logfile.txt
logfile.txt:
removed './emptyfile1'
removed './emptyfile0'
Or you can use pipes and xargs for a more clean output:
find . -type f -empty | xargs ls | tee -a logfile.txt | xargs rm
This will give you only deleted filenames.
I want to print with format Folder/Folder.
Instead of full paths:
/volume1/ArtWork/Folder1/folderA
/volume1/ArtWork/Folder1/folderB
/volume1/ArtWork/Folder2/folderA
/volume1/ArtWork/Folder2/folderA
I want to print in a txt "semi-paths" (not only filenames!):
Folder1/folderA
Folder1/folderB
Folder2/folderA
Folder2/folderA
This is what I am currently using:
find /volume1/ArtWork/* -type d -maxdepth 2 \
-not -empty -printf '%f\n' \
> /volume1/ArtWork/filenamesdir.txt
(I want to print not-empty folders, but the format at the moment is wrong)
I suggest to navigate to that folder before running the find command. Using -printf '%P\n' you can print the part of interest, each on a separate line:
pushd /volume1/ArtWork
find . -type d -maxdepth 2 -not -empty -printf '%P\n'
popd
Note that I'm using pushd/popd instead of cd. That makes changing into the directory and back to the previous one more convenient.
This will do:
find /volume1/ArtWork/* -maxdepth 2 -type d \
-exec sh -c 'echo $0 | grep -o "[^/]*/[^/]*$"' {} \; \
> /volume1/ArtWork/filenamesdir.txt
This is a gnu-sed version:
find /your/path -mindepth 1 -type d -print0 |
xargs -0 -I{} bash -c 'sed -r "s/.*\/(.*\/.*)$/\1/" <<<"{}"'
I am trying to copy files from one directory into another from certain modification date ranges. For example, copy all files created after May 10 from dir1 to dir2. I have tried a few things but have been unsuccessful so far.
This made sense to me but cp does not take the filenames piped to it, but just executes ./* and copies all files in the directory:
find . -type f -daystart -mtime 2 | cp ./* /dir/
This almost worked, but did not copy all of the matching files, I also tried xargs -s 50000, but did not work:
find . -type f -daystart -mtime 2 | xargs -I {} cp {} /dir/
find . -type f -daystart -mtime 2 | xargs cp -t /dir/
Found this online, does not work:
cp $(find . -type f -daystart -mtime 2) /dir/
Ideas? Thanks.
Given as your actual question is about using filenames from stdin rather than metadata from stdin, this is quite straightforward:
while IFS= read -r -d '' filename; do
cp "$filename" /wherever
done < <(find . -type f -daystart -mtime 2 -print0)
Note the use of IFS= read -r -d '' and -print0 -- as NUL and / are the only two characters which can't be used in UNIX filenames, using any other character, including the newline, to delimit them is unsafe. Think about what would happen if someone (or a software bug) created a file called $'./ \n/etc/passwd'; you want to be damned sure none of your scripts try to delete or overwrite /etc/passwd when they're trying to delete or overwrite that file.
That said, you don't actually need to use a pipe at all:
find . -type f -daystart -mtime -2 -exec cp '{}' /wherever ';'
...or, if you're only trying to support GNU cp, you can use this more efficient variant:
find . -type f -daystart -mtime -2 -exec cp -t /wherever '{}' +
You don't specify why the various attempts didn't work, so I can only assume that they are the result of whitespace in the filenames.
Try using find's useful -exec action instead of using xargs:
find . -type f -daystart -mtime 2 -exec cp {} /media/alex/Extra/Music/watchfolder/ \;
find . -type f -daystart -mtime 2 \
| cpio -pdv /media/alex/Extra/Music/watchfolder/
i am using the following command and getting an error "arg list too long".Help needed.
find ./* \
-prune \
-name "*.dat" \
-type f \
-cmin +60 \
-exec basename {} \;
Here is the fix
find . -prune -name "*.dat" -type f -cmin +60 |xargs -i basename {} \;
To only find files in the current directory, use -maxdepth 1.
find . -maxdepth 1 -name '*.dat' -type f -cmin +60 -exec basename {} \;
In all *nix systems the shell has a maximum length of arguments that can be passed to a command. This is measured after the shell has expanded filenames passed as arguments on the command line.
The syntax of find is find location_to_find_from arguments..... so when you are running this command the shell will expand your ./* to a list of all files in the current directory. This will expand your find command line to find file1 file2 file3 etc etc This is probably not want you want as the find is recursive anyway. I expect that you are running this command in a large directory and blowing your command length limit.
Try running the command as follows
find . -name "*.dat" -type f -cmin +60 -exec basename {} \;
This will prevent the filename expansion that is probably causing your issue.
Without find, and only checking the current directory
now=$(date +%s)
for file in *.dat; do
if (( $now - $(stat -c %Y "$file") > 3600 )); then
echo "$file"
fi
done
This works on my GNU system. You may need to alter the date and stat formats for different OS's
If you have to show only .dat filename in the ./ tree. Execute it without -prune option, and use just path:
find ./ -name "*.dat" -type f -cmin +60 -exec basename {} \;
To find all the .dat files which are older than 60 minutes in the present directory only do as follows:
find . -iregex "./[^/]+\.dat" -type f -cmin +60 -exec basename {} \;
And if you have croppen (for example aix) version of find tool do as follows:
find . -name "*.dat" -type f -cmin +60 | grep "^./[^/]\+dat" | sed "s/^.\///"
I want to recursively delete all files in some folders except those who have .gz extension. Normally I use
find /thepath -name "foo" -print0 | xargs -0 rm -rf
to recursively delete all folders named "foo" in the /thepath. But now I wan to add an exclusion option. How that is possible?
For example, the folder structure looks like
.hiddenfolder
.hiddenfolder/bin.so
arc.tar.gz
note.txt
sample
So I want to delete everything but keep arc.tar.gz
Find and delete all files under /thepath except with name matching *.gz:
# First check with ls -l
find /thepath -type f ! -name '*.gz' -print0 | xargs -0 ls -l
# Ok: delete
find /thepath -type f ! -name '*.gz' -print0 | xargs -0 rm -vf
Oh, and to delete all empty left-over directories:
find /thepath -type d -empty -print0 | xargs -0 rmdir -v
I think
find /thepath -name "foo" ! -name "*.gz" -print0
should produce the correct list of filenames, but check before piping the output to your xargs command to perform the actual deletions.
