Convert all png,jpeg,jpg to jpg and compress them using imagemagick










4















Im almost there with this code:



for PHOTO in /home/dvms/Desktop/projs/others/tests/gulp_test/src/images/*.png,jpeg,jpg
do
BASE=`basename $PHOTO`
convert "$PHOTO" -quality 50% "/home/dvms/Desktop/projs/others/tests/gulp_test/src/imagesCompressed/$BASE.jpg"
done


But the output files are appearing with their old file extension with a ".jpg" appended in the end, example: imageA.png.jpg .



How can solve this?

  • That's because you have this $BASE.jpg it should be $BASE%%.*.jpg

Replace the line:



BASE=`basename $PHOTO`


With this one:



BASE=`basename $PHOTO | cut -d. -f1`


Then try again.

  • Please remember to quote all variables, as BASE="$( basename "$PHOTO" | cut -d. -f1 )" (note two sets of quotation marks). Without them, if any file name contains a space or certain special characters, you run the risk of data corruption. Also, the cut command won't work if a file name contains two or more dots; this needs to be changed; it can also, in certain cases, cause data being overwritten. The answer by @GeorgeUdosen provides a good option.

Modify you code into this form:



for PHOTO in /home/dvms/Desktop/projs/others/tests/gulp_test/src/images/*.png,jpeg,jpg
do
BASE=$(basename $PHOTO)
convert "$PHOTO" -quality 50% "/home/dvms/Desktop/projs/others/tests/gulp_test/src/imagesCompressed/$BASE%.*.jpg"
done


Rather than this $BASE.jpg use $BASE%.* then add the extension.






share|improve this answer

























  • You might want "$BASE%.*" to use the shortest matching suffix pattern, so my.long.filename.jpg turns into my.long.filename.jpg, not my.jpg. Also, worth checking that the output doesn't already exist, in case of collisions between different source suffixes.

    – Peter Cordes
    Aug 25 '18 at 18:46











  • Also worth checking if the output file is actually smaller than the input, otherwise just copy or link. (Or check if the input jpg quality setting was below some threshold, but just comparing file size after an attempted recompression is easier and always works.)

    – Peter Cordes
    Aug 25 '18 at 18:47











  • Please add quotes: BASE="$( basename "$PHOTO" )"(two sets of quotes), in case the file name contains a space or certain other special characters.
