how to remove image files that are smaller than certain dimensions

I have already found an answer that lists pretty much everything. Except I cannot get it to work.



I use: 



find . -iname "*.jpg" -type f | xargs -I{} identify -format '%w %h %i' {} | awk '$1<300 || $2<300{print $3}'


What is needed to remove the output files?

I tried adding | rm at the end but an error shows that im missing an opperand. I want all the files that the code above prints to be deleted.



Can someone please help






rm pipe

  • I think you can use rm $(find...$3}'). In other words, wrap the above command inside the parens in $() to use the results as an argument to rm.

    rm doesn't read filenames from input. You can probably do:



    find . -iname "*.jpg" -type f -exec bash -c 'for i; do size=($(identify -format "%w %h" "$i")); (( size[1] < 300 || size[2] < 300 )) && rm -v "$i"' remove-files {} +



    • You can use -exec instead of xargs.


    The bash command:



    for i
    
do
    
    size=($(identify -format "%w %h" "$i"))
    
    (( size[1] < 300 || size[2] < 300 )) && rm -v "$i"
    
done



    • loops over all the input arguments (for i)

    • gets the size and stores it in an array (that's why there are parentheses around $(): ($(identify -format "%w %h" "$i"))

    • uses shell arithmetic (( )) to do the comparison

      The following works and is very fast.
      Save to ~/checksize.sh and make it executable with chmod (chmod +x ~/checksize.sh)



      #! /bin/bash
      

      
#find . -type f -exec bash -c ~/checksize.sh ;
      
echo ${@}
      
if [ -z "$1" ]
      
then
      
    echo "$1 empty" >&2
      
    exit
      
fi
      

      
size=($(identify -format "%w %h" "$1" | tr -d "()"))
      
#echo ${size[@]}
      
#echo ${size[0]}
      
#echo ${size[1]}
      
if [ ${size[0]} -lt 300 -a ${size[1]} -lt 300 ]
      
then
      
    rm -v "$1"
      
fi


      Then change directory into the directory you want to remove the files that are too small from.



      After cd'ing into the directory, run the following: find . -type f | xargs -P 0 -L 1 ~/checksize.sh



      It runs fast because it uses xarg's -P 0 which makes xarg run with the maximum amount of paralellity possible. See its man page for details.

                            The following works and is very fast.
                            Save to ~/checksize.sh and make it executable with chmod (chmod +x ~/checksize.sh)



                            #! /bin/bash

if [ -z "$1" ]
                            
then
                            
    echo "$1 empty" >&2
                            
    exit

size=($(identify -format "%w %h" "$1" | tr -d "()"))
                            
#echo ${size[@]}
                            
#echo ${size[0]}
                            
#echo ${size[1]}
                            
if [ ${size[0]} -lt 300 -a ${size[1]} -lt 300 ]

    rm -v "$1"
                            
fi


                            Then change directory into the directory you want to remove the files that are too small from.



                            After cd'ing into the directory, run the following: find . -type f | xargs -P 0 -L 1 ~/checksize.sh
