Bash: Look for files in certain folders and then c

Question

I'm new to Bash, and I'm trying to find files in a certain set of folders. I want to create a txt report for image files in each /check/ folder.

Here's what I've been working with:

# Find images
for f in */check/ ; do
    find ./ -iname "*jpg*" -o -iname "*png*" > find_images.txt
        echo "finished $f"
done

I can't figure out how to only look at subfolders named "check", and I also want to pass the variable so that I get separate text files named after the parent folders. Any suggestions?

Answer 1

Use grep command and pipe it with find command

find . | grep check 

Answer 2

The find command supports searching for directories (folders), e.g.

find . -name "check" -type d

You could use these results to then look for the files you want. The variable $f will be the name of the folder, so use that in the inner find command. Then if you want separate output files each time through the loop, use a variable in the filename. The $f variable will have slashes in the content, so you probably don't want to use that in the name of your output file. In my example, I use a counter to make sure each output file has a unique name.

count=1
for f in `find . -name "check" -type d` ; do
    find $f -iname "*jpg*" -o -iname "*png*" > find_images_$count_.txt
    count=$((count+1))
done

Answer 3

You're close, but you're not using $f which contains the folder's name:

# Find images
for f in */check/ ; do
    # Removing front-slashes from $f to use in log name
    # http://mywiki.wooledge.org/BashGuide/Parameters#Parameter_Expansion
    log_f="${f//\//_}"

    # Only search inside $f, saving results to find_images_[foldername].txt
    find "$f" -iname "*jpg*" -o -iname "*png*" > "find_images_${log_f}.txt"

    echo "finished $f"
done
