Currently, I am using this
unrar e -r *.rar
To extract files, however this puts everything in my root unraring folder. Current structure
/HomeFolder
/Nextlevel
/RarFolder
rarfile.rar
I want the output to be
/HomeFolder
/Nextlevel
raroutput.ext
How would I do change my command to do this?
Try to use following approach:
find /HomeFolder -type d -name 'RarFolder' -printf '%h\n' | xargs -I{} sh -c 'cd {}; unrar e -r *.rar'
It searches for all nested 'RarFolder' subdirectories in '/HomeFolder', running your unrar command from within subdir containing 'RarFolder' (i.e. '/HomeFolder/Nextlevel' in your example).
To extract files to parent directory of one, containing '*.rar' files, command can be adjusted as:
find /HomeFolder -type f -name '*.rar' -printf '%h\n' | xargs -I{} sh -c 'cd {}/..; unrar e -r *.rar'

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 "$dir/" -iname '*' -print0 | xargs -0 mv -t /files/dump/
done
Instead of iterating, you could just use find. In man-page there is a "-type" option documented, so for moving only files you could do:
find "/files/media/documents/" -type f -print0 | xargs -0 mv -t /files/dump/
You also won't like to find files in /files/media/documents/, but all sub-directories? Simply add "-mindepth":
find "/files/media/documents/" -type f -mindepth 1 -print0 | xargs -0 mv -t /files/dump/
Alternatively you could also use "-exec" to skip a second command (xargs):
find "/files/media/documents/" -type f -mindepth 1 -exec mv {} /files/dump/ \;
I have several parent folders like GJ1, GJ2 etc. Each of these folders contain three images like GJ11_F.jpg, GJ11_P.jpg. I need to only display all the GJ11_F.jpg files including their respective parent directories.
find . -type f -name "*_F.jpg" | xargs cp -t ~/home/ubuntu/
but the above command will only copy the *_F.jpg files and not their respective parent directories GJ1.
Is xargs not the one im supposed to try?
I have also tried -
find . -name "*_F.jpg" -exec sh -c 'rsync -a "${0%/*}" ~/home/ubuntu/' {} \;
One easy way is to use tar which will deal with the directories automatically:
find . -type f -name "*_F.jpg" -print0 | tar c --null -T - | tar xC ~/home/ubuntu/
And here's a solution with a while loop:
find . -type f -name "*_F.jpg" -print0 |
while IFS= read -r -d '' file; do
mkdir -p ~/home/ubuntu/"$(dirname -- "$file")"
cp -ai -- "$file" ~/home/ubuntu/"$file"
done
I'm trying to create a new folder in an existing tree with :
find /home/a/Desktop/MyCycles/DavidSilver -type d -exec sh -c '(cd {} && mkdir bin)' ';'
In Ubuntu , but I get an infinite loop of
mkdir: cannot create directory ‘bin’: File exists
Which BTW is not true , since the folder doesn't exist in each of the subfolders of /home/a/Desktop/MyCycles/DavidSilver .
Any idea how can I fix this ?
Thanks
Assuming GNU find(1):
find /home/a/Desktop/MyCycles/DavidSilver -type d -printf '%p/bin\0' | xargs -0 mkdir
Withtout GNU find(1), but assuming directory names don't contain newlines:
find /home/a/Desktop/MyCycles/DavidSilver -type d | \
sed 's!$!/bin!' | \
xargs mkdir
I have the following directories:
P922_101
P922_102
.
.
Each directory, for instance P922_101 has following subdirectories:
140311_AH8MHGADXX 140401_AH8CU4ADXX
Each subdirectory, for instance 140311_AH8MHGADXX has the following files:
1_140311_AH8MH_P922_101_1.fastq.gz 1_140311_AH8MH_P922_101_2.fastq.gz
2_140311_AH8MH_P922_101_1.fastq.gz 2_140311_AH8MH_P922_101_2.fastq.gz
And files in 140401_AH8CU4ADXX are:
1_140401_AH8CU_P922_101_1.fastq.gz 1_140401_AH8CU_P922_4001_2.fastq.gz
2_140401_AH8CU_P922_101_1.fastq.gz 2_140401_AH8CU_P922_4001_2.fastq.gz
I want to do 'cat' for the files in the subdirectories in the following way:
cat 1_140311_AH8MH_P922_101_1.fastq.gz 2_140311_AH8MH_P922_101_1.fastq.gz
1_140401_AH8CU_P922_101_1.fastq.gz 2_140401_AH8CU_P922_101_1.fastq.gz > P922_101_1.fastq.gz
which means that files ending with _1.fastq.gz should be concatenated into a single file and files ending with _2.fatsq.gz into another file.
It should be run for all files in subdirectories in all directories. Could someone give a linux solution to do this?
Since they're compressed, you should probably use gzip -dc (decompress and write to stdout) -
find /somePath -type f -name "*.fastq.gz" -exec gzip -dc {} \; | \
tee -a /someOutFolder/out.txt
You can use find for this:
find /top/path -mindepth 2 -type f -name "*_1.fastq.gz" -exec cat {} \; > one_file
find /top/path -mindepth 2 -type f -name "*_2.fastq.gz" -exec cat {} \; > another_file
This will look for all the files starting from /top/path and having a name matching the pattern _1.fastq.gz / _2.fastq.gz and cat them into the desired file. -mindepth 2 makes find look for files that are at least under the current directory; this way, files in /top/path won't be matched.
Note that you will probably need zcat instead of cat, for gz files.
As you keep adding details in comments, let's see what else we can do:
Say you have the list of directories in a file directories_list, each line containing one:
while read directory
do
find $directory -mindepth 2 -type f -name "*_1.fastq.gz" -exec cat {} \; > $directory/output
done < directories_list
I have a main directory with 361 subdirectories. Within the each subdirectory, there is a parameter file and one executable program file. The executable file is coded to look for the parameter file in the directory where the executable is located. (The same executable file is in all subdirectories. The parameter files all have the same file name in all subdirectories)
Instead of executing the program file individually, is there a cshell command for terminal to run them all at once?
UPDATED
If your Linux is so old it doesn't have -execdir, you could try this:
find $(pwd) -name YourProgram -exec dirname {} \; | while read d; do cd "$d" && pwd; done
If that correctly prints the names of the directories where your program needs to be run, just remove the pwd and replace with whatever you want done in tha directory - presumably something like this:
find $(pwd) -name YourProgram -exec dirname {} \; | while read d; do cd "$d" && ./YourPrgram; done
ORIGINAL ANSWER
Like this maybe:
find . -type f -name YourProgramName -execdir ./YourProgramName YourParameterFile \;
But backup first and check it looks right before using.
The -execdir causes find to change to the directory it has found before running the commands there.
If your command is more complicated, you can do this:
find . -type f -name YourProgramName -execdir sh -c "command1; command2; command3" \;
Check it does what you want like this:
find . -type f -name YourProgramName -execdir pwd \;
Maybe this will help. Suppose you have in each folder a file named params_file and an executable named exec_file, then:
for dir in `find . -maxdepth 1 -mindepth 1 -type d` ; do
cd $dir
cat params_file | xargs ./exec_file
cd ..
done
