Bash rename zips in subdirectories

Question

Hi have a bunch of folders with one zip file in it the paths look like this

/folder/subfolder/archive.zip
/folder/subfolder1/archive1.zip
/folder/subfolder2/archive2.zip
/folder/subfolder3/zip3.zip
/folder/subfolder4/zip4.zip
etc...

I need the out put to be like this

/folder/subfolder/preview.zip
/folder/subfolder1/preview.zip
/folder/subfolder2/preview.zip
/folder/subfolder3/preview.zip
/folder/subfolder4/preview.zip
etc...

Each folder also only has one zip in it so i don't have to work about overwriting and what not i just need each zip in each folder renamed to preview.zip no matter the name in each subdirectory how can i do that in bash?

Thank you for any help

Answer 1

Something like this should do the job:

for j in **/*.zip; do mv "$j" "${j%/*.zip}/preview.zip"; done

As pointed out by SiegeX, note that to use recursive globbing you've got to set the globstar option and that is only available in bash 4.x

Answer 2

You can do this with Bash's parameter substitution:

bash-3.2$ for archive in folder/subfolder*/*.zip; do
    echo "Archive = ${archive}, Preview = ${archive%/*}/preview.zip"
done
Archive = folder/subfolder/archive.zip, Preview = folder/subfolder/preview.zip
Archive = folder/subfolder1/archive1.zip, Preview = folder/subfolder1/preview.zip
Archive = folder/subfolder2/archive2.zip, Preview = folder/subfolder2/preview.zip
Archive = folder/subfolder3/zip3.zip, Preview = folder/subfolder3/preview.zip
Archive = folder/subfolder4/zip4.zip, Preview = folder/subfolder4/preview.zip

Where ${archive%/*} will strip off everything from the last / in ${archive} .

This will allow you to verify the command that will run. Change this to:

mv "${archive}" "${archive%/*}/preview.zip" 

... to rename the files (even if they have whitespace in their names).

Answer 3

#!/bin/bash
while read file; do
  echo mv "$file" "${file%/*}/preview.zip"
done < <(find /folder -type f -name "archive*.zip")

Note : Remove the echo if the output looks sufficient and rerun the script to make the actual changes

Answer 4

This might work for you, but it's not fully tested:

find /folder -maxdepth 1 -mindepth 1 -type d -exec mv {}/archive*.zip {}/preview.zip \;

Working very strictly under your example, this should find all directories under /folder , with a maximum and minimum depth of 1 (ie only directories within /folder , since that seems to be what you want) and executes a mv command for a file under each.
