Manage Picture on Ubuntu System
Manage Picture on Ubuntu SystemThese days, I have a lot of photos with large size on my computer. I need to deal with that and post
them to my blog. So, I will change the size from large to small, first.
First of all, I install the image tool
>sudo apt-get install imagemagick
Transfer the picture data files to jpg format
>convert $img $_basefullname;
We can write a shell to do this
>vi transpic.sh
#!/bin/sh
for img in `find ./ -name "*."`; do
#change upper filename to lower
_imglower=`echo $img|tr "[:upper:]" "[:lower:]"`;
#get file's basename
_basename=`basename $_imglower .bmp`;
#get file's dir
_dirname=`dirname $img`;
#get desc filename with path
_basefullname=$_dirname"/"$_basename".jpg";
#do convert
convert $img $_basefullname;
#remove bmp file
rm $img;
echo "deal $_basefullname successfully";
done
Resize and change quality of the picture
>convert -resize 35%*35% -quality 20 $img $img-resized;
We can provide a shell to do this
>vi 50zippic.sh
for img in `find ./ -name "*."`; do
convert -resize 35%*35% -quality 20 $img $img-resized;
rm $img;
mv $img-resized $img
echo $img
done
for img in `find ./ -name "*."`; do
convert -resize 35%*35% -quality 20 $img $img-resized;
rm $img;
mv $img-resized $img
echo $img
done
for img in `find ./ -name "*."`; do
convert -resize 35%*35% -quality 20 $img $img-resized;
rm $img;
mv $img-resized $img
echo $img
done
Give the rights to execute these shell:
luohua@luohua-Vostro-3400:~$ chmod +x zippic.sh
luohua@luohua-Vostro-3400:~$ chmod +x transpic.sh
Copy the shell files to bin directory.
luohua@luohua-Vostro-3400:~$ sudo cp zippic.sh /bin
luohua@luohua-Vostro-3400:~$ sudo cp transpic.sh /bin
It is done. You can run this commands in your picture direcories.
