Find & delete

gabriel — Sun, 15 May 2011 13:34:58 +0000

Sometime it happen that I need to find all certain type of file or directory from a folder and sub folders and delete it. An example is if you have to copy a project under svn and you want to clean all folder from “.svn” folder.

Via linux shell:

$ find /absolute/or/relative/path  -type d -name ".svn" | xargs rm -r

If you have to delete file or folder with name first letter “A”:

$ find /absolute/or/relative/path -name "A*" -print0 | xargs -0 rm -r

The print0 and -0 parameter means that the name ending with null char, otherwise will be used spaces

Copy all pictures from subdirectories:

find . -type f -name “*.jpg” -print0 | xargs -0 cp -fR –target-directory=/path/to/destination

Imagemagick, mass resize photos

gabriel — Sat, 14 May 2011 09:46:36 +0000

I use Imagemagick when I have a lot of pictures that need to be resized for being used on a website. From a shell, the command for resize a picture is:

$ mogrify -resize x file.jpg

For resize all pictures inside a folder, via shell move to the folder and give:

$ mogrify -resize x *

Some time pictures are in more sub-folder, and is not very comfortable move to each folder for launch the resize command.
You can use a simple “batch script”, move to the folder via shell and give:

$ find . -type f | xargs mogrify -resize x {}

For resize only .jpg files:

$ find . -type f -name "*.jpg" | xargs mogrify -resize x {}

N.b. name is case sensitive

Resize if bigger or smaller than

If you want to resize the file only if bigger or smaller than the values used for resize use (bigger than) > or (smaller than) < :

$ mogrify -resize '1000x1000>' *
