I want to rename folder with case-sensitive option. for example:
mv "foldername1" "foldername2"
an error occuring in this command, because name of my folder isn't "foldername1", it is "FolderName1".
How can I use rename (mv) command to rename case-sensitive named folders?
ls | grep -i foldername1 | xargs -I {} mv {} foldername2
Warning: You would not like to use this when multiple candidate files (eg. if foldername1 and Foldername1 are both present).
Use the find command:
find . -iname foldername1 -exec mv '{}' foldername2 ;

I want to copy all the log files from a directory which does not contain log files, but it contains other subdirectories with log files. These subdirectories also contain other subdirectories, so I need something recursive.
I tried
cp -R *.log /destination
But it doesn't work because the first directory does not contains log files. The response can be also a loop in bash.
find /path/to/logdir -type f -name "*.log" |xargs -I {} cp {} /path/to/destinationdir
Explanation:
find searches recursively
-type f tells you to search for files
-name specifies the name pattern
xargs executes commands
-I {} indicates an argument substitution symbol
Another version without xargs:
find /path/to/logdir -type f -name '* .log' -exec cp '{}' /path/to/destinationdir \;
In Linux I'm trying to find a file in a directory, backup it with another name and, then, replace it with another one.
I tried the first two actions with these commands
find foldername -name filename.html; -exec sed -i .bak;
but it's says
bash: -exec: command not found
Try this:
find foldername -name filename.html -exec cp -vp {}{,.bak} \; -exec truncate -s 0 {} \;
This uses find's exec option like it looks like you tried to use. Then cp copies the file (specified with {}) and appends .bak to the copy and preserves what it can with the p option:
preserve the specified attributes (default:
mode,ownership,timestamps), if possible additional attributes:
context, links, xattr, all
This leaves the original file in place as well.
You can do the following:
find . -name 'FILE_PATTERN_HERE' | xargs -I file_name cp file_name file_name.bkp
You can pipe the output of find command to cp using xargs. Here file_name acts as the output of find.
Example
find . -name 'logback.xml*'
Output:
./logback.xml
./apache-cassandra-3.11.1/conf/logback.xml
After running the command
find . -name 'logback.xml*' | xargs -I file_name cp file_name file_name.bkp
find . -name 'logback.xml*'
Output:
./logback.xml
./apache-cassandra-3.11.1/conf/logback.xml
./apache-cassandra-3.11.1/conf/logback.xml.bkp
./logback.xml.bkp
I have a Linux-System where some users put files with ftp in a Directory. In this Directory there are sub-directories which the users can create. Now I need a script that searches for all files in those subdirectories and moves them in a single Directory (for backup). The Problem: The Sub directories shouldn´t be removed.
the directory for the users is /files/media/documents/
and the files have to be moved in the Directory /files/dump/. I don´t care about files in /files/media/documents/, they are already handled by another script.
I already tried this script:
for dir in /files/media/documents/
do
find "$dir/" -iname '*' -print0 | xargs -0 mv -t /files/dump/
done
Instead of iterating, you could just use find. In man-page there is a "-type" option documented, so for moving only files you could do:
find "/files/media/documents/" -type f -print0 | xargs -0 mv -t /files/dump/
You also won't like to find files in /files/media/documents/, but all sub-directories? Simply add "-mindepth":
find "/files/media/documents/" -type f -mindepth 1 -print0 | xargs -0 mv -t /files/dump/
Alternatively you could also use "-exec" to skip a second command (xargs):
find "/files/media/documents/" -type f -mindepth 1 -exec mv {} /files/dump/ \;
I want to recursively delete all binary files in a folder under linux using the command-line or a bash script. I found
grep -r -m 1 "^" path/to/folder | grep "^Binary file"
to list all binary files in path/to/folder at How to list all binary file extensions within a directory tree?. I would now like to delete all these files.
I could do
grep -r -m 1 "^" path/to/folder | grep "^Binary file" | xargs rm
but that is rather fishy as it also tries to delete the files 'Binary', 'file', and 'matches' as in
rm: cannot remove ‘Binary’: No such file or directory
rm: cannot remove ‘file’: No such file or directory
rm: cannot remove ‘matches’: No such file or directory
The question is thus how do I delete those files correctly ?
This command will return all binary executable files recursively within a directory, run this first to ensure proper output.
find . -type f -executable -exec sh -c "file -i '{}' | grep -q 'x-executable; charset=binary'" \; -print
If that works you can pass the output to xargs to delete these files.
find . -type f -executable -exec sh -c "file -i '{}' | grep -q 'x-executable; charset=binary'" \; -print | xargs rm -f
Hope this helped, have an awesome day! :)
I coded a tool, called blobs, that lists runable binaries.
Its readme mentions how to pipe to any other command.
This should do the job, if you are deleting a lot of binrary files in a folder.
find . -type f -executable | xargs rm
I want to create a loop in Linux script that will go thru the folders in one directory and will copy photos to one folder and will overwrite photos that have the same name. Can anyone point me in the write direction?
find /path/to/source -type f -exec cp -f {} /path/to/destination \;
Would that work? Keep in mind, that will overwrite files without asking.
If you want it to confirm with you before overwriting, use the -i flag (for interactive mode) in the cp command.
find /path/to/source -type f | xargs -I {} file {} | grep <JPEG or image type> | cut -d ":" -f1 | xargs -I {} cp -rf {} /path/to/destination
With this you can find tune your copy with selecting only the image type.
Actually, you need not to loop through folders for finding photos using script, find command will do that job for you.
Try using find with xargs and cp
find source_dir -type f -iname '*.jpg' -print0 | xargs -0 -I {} cp -f {} dest_dir
Replace *.jpg with format of your photo files. (e.g. *.png etc.)
Note the use of -f option of cp, since you want to overwrite photos with the same name
