I want to give a long list (with ls -l) of all the files in home directory that is writable by user, how can I combine find and ls -l?
find ~/ -maxdepth 1 -exec ls -l '{}' \;
If you are strictly interested only in files, i.e., no folders then you can tune the last command in the following way
find ~/ -maxdepth 1 -type f -exec ls -l '{}' \;
Check your man page for "find". It has a -ls action that you can tag on to the end:
-ls True; list current file in ls -dils format on standard output.

I'm trying to find projects in an enormous directory. The projects are always several levels of depth in and have a config file which contains the project name. So basically...
Given a path and string
Return any directory that has a depth of 3 from the and contains a file named "config"
that contains the
I learned that find combined with grep will work... but print out the grepped text and not the path of it's parent directory
find <starting-dir> -maxdepth 3 -mindepth 3 -type d -exec grep '<project-name>' {}/config \;
Just prints out the project name :(
Perhaps there any way to switch back to find's default behaviour of printing out the found file path only if the grep is successful? Or is there another tool I should try to use to solve this?
To get -print, you need to add it explicitly after a succesful -exec.
For example, using grep's -q:
find <starting-dir> \
-maxdepth 3 -mindepth 3 \
-type d \
-exec grep -q '<project-name>' {}/config \; \
-print
As you discovered, grep already has -l.
You can reduce the number of grep processes:
find <starting-dir> \
-maxdepth 4 -mindepth 4 \
-type f -name config \
-exec grep -l '<project-name>' {} +
Adding the -l flag to my output fixes the issue, for some reason I thought that would just print out "config" and not the whole path of that config file, but here we are.
find <starting-dir> -maxdepth 3 -mindepth 3 -type d -exec grep -l '<project-name>' {}/config \;
This will print out the full path of the config file of the project you search for.
I want to find some folders by name, and then list their information using "ls", here is what i did using "find",
find ./ -mindepth 1 -maxdepth 3 -type d -name logs
what i got is:
./RECHMN32Z/US/logs
./RECHMN32Z/UM/logs
./RECHMP3BL/US/logs
./RECHMP3BL/UM/logs
./RECHMAS86/UM/logs
./RECHMAS86/US/logs
and then i add "xargs ls -l" , then it will return information of all files under these folders returned above,
if i just want to list information of these folders, how to do ?
It's not find or xargs's fault, but ls's. When given directory names ls shows their contents. You can use -d to have it only show the directories themselves.
find has a -ls action that uses the same format as ls -dils. No need to invoke an external command.
find ./ -mindepth 1 -maxdepth 3 -type d -name logs -ls
Or use ls -ld to list the directories and not their contents. -exec cmd {} + is a simpler alternative to xargs. No pipeline required.
find ./ -mindepth 1 -maxdepth 3 -type d -name logs -exec ls -ld {} +
I'm using a find command which results in multiple lines for result, I then want to pipe each of those lines into an ls command with the-l option specified.
find . -maxdepth 2 -type f |<some splitting method> | ls -l
I want to do this in one "command" and avoid writing to a file.
I believe this is what you are looking for:
find . -maxdepth 2 -type f -exec ls -l {} \;
Explanation:
find . -maxdepth 2 -type f: find files with maxdepth at 2
-exec ls -l {} \; For each such result found, run ls -l on it; {} specifies where the results from find would be substituted into.
The typical approach is to use -exec:
find . -maxdepth 2 -type f -exec ls -l {} \;
Sounds like you are looking for xargs. For example, on a typical Linux system:
find . -maxdepth 2 -type f -print0 | xargs -0 -n1 ls -l
How can I display all files greater than 10k bytes in my current directory and it's subdirectories.
Tried ls -size +10k but that didn't work.
find . -size +10k -exec ls -lh {} \+
the first part of this is identical to #sputnicks answer, and sucesffully finds all files in the directory over 10k (don't confuse k with K), my addition, the second part then executes ls -lh or ls that lists(-l) the files by human readable size(-h). negate the h if you prefer. of course the {} is the file itself, and the \+ is simply an alternative to \;
which in practice \; would repeat or:
ls -l found.file; ls -l found.file.2; ls -l found.file.3
where \+ display it as one statement or:
ls -l found.file found.file.2 found.file.3
more on \; vs + with find
Additionaly, you may want the listing ordered by size. Which is relatively easy to accomplish. I would at the -s option to ls, so ls -ls and then pipe it to sort -n to sort numerically
which would become:
find . -size +10k -exec ls -ls {} \+ | sort -n
or in reverse order add an -r :
find . -size +10k -exec ls -ls {} \+ | sort -nr
finally, your title says find biggest file in directory. You can do that by then piping the code to tail
find . -size +10k -exec ls -ls {} \+ | sort -n | tail -1
would find you the largest file in the directory and its sub directories.
note you could also sort files by size by using -S, and negate the need for sort. but to find the largest file you would need to use head so
find . -size +10k -exec ls -lS {} \+ | head -1
the benefit of doing it with -S and not sort is one, you don't have to type sort -n and two you can also use -h the human readable size option. which is one of my favorite to use, but is not available with older versisions of ls, for example we have an old centOs 4 server at work that doesn't have -h
Try doing this:
find . -size +10k -ls
And if you want to use the binary ls :
find . -size +10k -exec ls -l {} \;
I realize the assignment is likely long over. For anyone else:
You are overcomplicating.
find . -size +10k
I'll add to #matchew answer (not enough karma points to comment):
find . -size +10k -type f -maxdepth 1 -exec ls -lh {} \; > myLogFile.txt
-type f :specify regular file type
-maxdepth 1 :make sure it only find files in the current directory
You may use ls like that:
ls -lR | egrep -v '^d' | awk '$5>10240{print}'
Explanation:
ls -lR # list recursivly
egrep -v '^d' # only print lines which do not start with a 'd'. (files)
only print lines where the fifth column (size) is greater that 10240 bytes:
awk '$5>10240{print}'
How do I find all the files that were create only today and not in 24 hour period in unix/linux
On my Fedora 10 system, with findutils-4.4.0-1.fc10.i386:
find <path> -daystart -ctime 0 -print
The -daystart flag tells it to calculate from the start of today instead of from 24 hours ago.
Note however that this will actually list files created or modified in the last day. find has no options that look at the true creation date of the file.
find . -mtime -1 -type f -print
To find all files that are modified today only (since start of day only, i.e. 12 am), in current directory and its sub-directories:
touch -t `date +%m%d0000` /tmp/$$
find . -type f -newer /tmp/$$
rm /tmp/$$
Source
I use this with some frequency:
$ ls -altrh --time-style=+%D | grep $(date +%D)
After going through many posts I found the best one that really works
find $file_path -type f -name "*.txt" -mtime -1 -printf "%f\n"
This prints only the file name like
abc.txt not the /path/tofolder/abc.txt
Also also play around or customize with -mtime -1
This worked for me. Lists the files created on May 30 in the current directory.
ls -lt | grep 'May 30'
Use ls or find to have all the files that were created today.
Using ls : ls -ltr | grep "$(date '+%b %e')"
Using find : cd $YOUR_DIRECTORY; find . -ls 2>/dev/null| grep "$(date '+%b %e')"
find ./ -maxdepth 1 -type f -execdir basename '{}' ';' | grep `date +'%Y%m%d'`
You can use find and ls to accomplish with this:
find . -type f -exec ls -l {} \; | egrep "Aug 26";
It will find all files in this directory, display useful informations (-l) and filter the lines with some date you want... It may be a little bit slow, but still useful in some cases.
Just keep in mind there are 2 spaces between Aug and 26. Other wise your find command will not work.
find . -type f -exec ls -l {} \; | egrep "Aug 26";
If you're did something like accidentally rsync'd to the wrong directory, the above suggestions work to find new files, but for me, the easiest was connecting with an SFTP client like Transmit then ordering by date and deleting.
To get file before 24 hours execute below command:
find . -type f -mtime 1 -exec ls -l {} \;
To get files created today execute below command:
find . -type f -mtime -1 -exec ls -l {} \;
To Get files created before n days before, where +2 is before 2 days files in below command:
find . -type f -mtime +2 -exec ls -l {} \;
