I have a a directory with zip archives containing .jpg, .png, .gif images. I want to unzip each archive taking the images only and putting them in a folder with the name of the archive.
So:
files/archive1.zip
files/archive2.zip
files/archive3.zip
files/archive4.zip
Open archive1.zip - take sunflower.jpg, rose_sun.gif. Make a folder files/archive1/ and add the images to that folder, so files/archive1/folder1.jpg, files/archive1/rose_sun.gif. Do this to each archive.
I really don't know how this can be done, all suggestions are welcome. I have over 600 archives and an automatic solution would be a lifesaver, preferably a linux solution.
In Short
You can do this with a one-liner find + unzip.
find . -name "*.zip" -type f -exec unzip -jd "images/{}" "{}" "*.jpg" "*.png" "*.gif" \;
In Detail
unzip allows you to specify the files you want:
unzip archive.zip "*.jpg" "*.png" "*.gif"
And -d a target directory:
unzip -d images/ archive.zip "*.jpg" "*.png" "*.gif"
Combine that with a find, and you can extract all the images in all zips:
find . -name "*.zip" -type f -exec unzip -d images/ {} "*.jpg" "*.png" "*.gif" \;
Using unzip -j to junk the extraction of the zip's internal directory structure, we can do it all in one command. This gives you the flat image list separated by zip name that you desire as a one-liner.
find . -name "*.zip" -type f -exec unzip -jd "images/{}" "{}" "*.jpg" "*.png" "*.gif" \;
A limitation is that unzip -d won't create more than one new level of directories, so just mkdir images first. Enjoy.
7zip can do this, and has a Linux version.
mkdir files/archive1
7z e -ofiles/archive1/ files/archive1.zip *.jpg *.png *.gif
(Just tested it, it works.)
Something along the lines of:
#!/bin/bash
cd ~/basedir/files
for file in *.zip ; do
newfile=$(echo "${file}" | sed -e 's/^files.//' -e 's/.zip$//')
echo ":${newfile}:"
mkdir tmp
rm -rf "${newfile}"
mkdir "${newfile}"
cp "${newfile}.zip" tmp
cd tmp
unzip "${newfile}.zip"
find . -name '*.jpg' -exec cp {} "../${newfile}" ';'
find . -name '*.gif' -exec cp {} "../${newfile}" ';'
cd ..
rm -rf tmp
done
This is tested and will handle spaces in filenames (both the zip files and the extracted files). You may have collisions if the zip file has the same file name in different directories (you can't avoid this if you're going to flatten the directory structure).
You can write a program using a zip library. If you do Mono, you can use DotNetZip.
The code would look like this:
foreach (var archive in listOfZips)
{
using (var zip = ZipFile.Read(archive)
{
foreach (ZipEntry e in zip)
{
if (IsImageFile(e.FileName))
{
e.FileName = System.IO.Path.Combine(archive.Replace(".zip",""),
System.IO.Path.GetFileName(e.FileName));
e.Extract("files");
}
}
}
}
Perl's Archive-Zip is a good library for zipping/unzipping.
Here's my take on the first answer...
#!/bin/bash
cd files
for zip_name in *.zip ; do
dir_name=$(echo "${zip_name}" | sed -e 's/^files.//' -e 's/.zip$//')
mkdir ${dir_name}
7z e -o${dir_name}/ ${zip_name} *.jpg *.png *.gif
done
or, if you'd just like to use the regular unzip command...
unzip -d ${dir_name}/ ${zip_name} *.jpg *.png *.gif
I haven't tested this, but it should work... or something along these lines. Definitely more efficient than the first solution. :)
Hope this helps!

find -name archive.zip -exec unzip {} file.txt \;
This command finds all files named archive.zip and unzips file.txt to the folder that I execute the command from, is there a way to unzip the file to the same folder where the .zip file was found? I would like file.txt to be unzipped to folder1.
folder1\archive.zip
folder2\archive.zip
I realize $dirname is available in a script but I'm looking for a one line command if possible.
#iheartcpp - I successfully ran three alternatives using the same base command...
find . -iname "*.zip"
... which is used to provide the list of / to be passed as an argument to the next command.
Alternative 1: find with -exec + Shell Script (unzips.sh)
File unzips.sh:
#!/bin/sh
# This will unzip the zip files in the same directory as the zip are
for f in "$#" ; do
unzip -o -d `dirname $f` $f
done
Use this alternative like this:
find . -iname '*.zip' -exec ./unzips.sh {} \;
Alternative 2: find with | xargs _ Shell Script (unzips)
Same unzips.sh file.
Use this alternative like this:
find . -iname '*.zip' | xargs ./unzips.sh
Alternative 3: all commands in the same line (no .sh files)
Use this alternative like this:
find . -iname '*.zip' | xargs sh -c 'for f in $#; do unzip -o -d `dirname $f` $f; done;'
Of course, there are other alternatives but hope that the above ones can help.
Is there a way to unzip all gz files in the folder containing the zipfiles. When zip files are in subdirectories.
A query for
find -type f -name "*.gz"
Gives results like this:
./datasets/auto/auto.csv.gz
./datasets/prnn_synth/prnn_synth.csv.gz
./datasets/sleep/sleep.csv.gz
./datasets/mfeat-zernike/mfeat-zernike.csv.gz
./datasets/sonar/sonar.csv.gz
./datasets/wine-quality-white/wine-quality-white.csv.gz
./datasets/ring/ring.csv.gz
./datasets/diabetes/diabetes.csv.g
If you want, for each of those, to launch "gzip -d" on them:
cd theparentdir && gzip -d $(find ./ -type f -name '*.gz')
and then, to gzip them back:
cd theparentdir && gzip $(find ./ -type f -name '*.csv')
This will however choke in many cases
if filenames have some special characters (spaces, tabs, newline, etc) in them
other similar cases
or if there are TOO MANY files to be put after the gzip command!
A solution would be instead, if you have GNU find, to do :
find ... -print0 | xarsg -0 gzip -d # for the gunzip one, but still choke on files with "newline" in them
Another (arguably better?) solution, if you have GNU find at your disposal:
cd theparentdir && find ./ -type f -name '*.gz' -exec gzip -d '{}' '+'
and to re-zip all csv in that parentdir & all subdirs:
cd theparentdir && find ./ -type f -name '*.csv' -exec gzip '{}' '+'
"+" tells GNU find to try to put as many found files as it can on each gzip invocation (instead of doing 1 gzip incocation per file, very very ressource intensive and very innefficient and slow), similar to xargs, but with some benefits (1 command only, no pipe needed)
There is an option for recursivity (-r).
gzip -dr ./datasets
All archive will be decompressed in their own directory.
Example: gzip -dr ./a
a/b/c/test1.gz
a/b/d/test2.gz
a/e/test3.gz
After execution:
a/b/c/test1
a/b/d/test2
a/e/test3
I am trying to create a script for linux that will make a list with all files inside all zip files from a directory.
#! /bin/bash
for file in `find /home -iname "*.zip*" -type f`
do
unzip -l $(echo ${file}) >> /home/list.txt
done
It works, but only when there are no white spaces in filename.
What can I do to make it work ?
You can use the find command to execute a command for each file it finds. Perhaps try something like:
find /home -iname "*.zip*" -type f -exec unzip -l {} \; > /home/list.txt
I am trying to put together a script which will run through all the files on my server (under various subdirectories) , look for .jpeg files and run them through a translator which converts them to non progressive jpgs.
I have:
find /home/disk2/ -type f -iname "*.jpg"
Which finds all the files.
Then if it finds for example 1.jpg, I need to run:
/usr/bin/jpegtrans /file location/1.jpg > /file location/1.jpg.temp
The jpegtrans app converts the file to a temp file which needs to replace the original file.
So then I need to delete the original and rename 1.jpg.temp to 1.jpg
rm /file location/1.jpg
mv /file location/1.jpg.temp /file location/1.jpg
I can easily do this for single files but i need to do it for 100's on my server.
Use find with -exec:
find /home/disk2/ -type f -iname "*.jpg" -exec sh -c "/usr/bin/jpegtrans {} > {}.temp; mv -f {}.temp {}" \;
EDIT: For handling spaces in filenames, say:
find /home/disk2/ -type f -iname "*.jpg" -exec sh -c "/usr/bin/jpegtrans '{}' > '{}.temp'; mv -f '{}.temp' '{}'" \;
I have a folder in ~/Downloads with lots of
files and folders scattered. This consists of various files of different
extensions. I need to copy only the
.pdf files within various directories to ~/pdfs
Use find:
find ~/Downloads -type f -name "*.pdf" -exec cp {} ~/pdfs \;
if ~/pdfs exists in your system use the following command
cd ~/Downloads ; cp -r *.pdf ~/pdfs
if ~/pdfs does not exists in your system use the following command
cd ~/Downloads ; mkdir ~/pdfs ; cp -r *.pdf ~/pdfs
In order to deal with potential file names with spaces, etc., I would recommend this approach:
find ~/Downloads/. -type f -name "*.pdf" -print0 | xargs -0 -I_ cp _ ~/pdfs/.
