Good day, I am using Montage to create a Contact_Sheet.jpg in several direcrories, one contact sheet per directory. However some of the directories have small video files (.mp4 or .mpg) along with the JPG, TIFF, PNG and RAW files, is there a way to specifically exclude files such --exclude *,mpg ? or similar.

ImageMagick 7.0.7-22 Q16 x86_64 2018-01-13 for Mac OSX

Thanks in advance

You can just list the formats you want. For example:

This will exclude jpg from the directory
where i have use

ls | grep -v "\.jpg$"

to make a list of all files in the directory excluding .jpg

Search google and you will find other methods.

Excellent, thanks for the help guys this is great.
The excluding specific formats with Grep seems like a great way to go.
$(ls | grep -v "\.mpg$")

Also, most versions of "ls" will accept an "--ignore" option. To omit the MPGs from the listing, try something like this...

That does not work on my Mac. I tried it.

At least on my installation the "ls" that comes with Windows 10 bash accepts that "--ignore" option. Maybe it's not as common as I thought.

I have an "ls" that comes as part of a GNU32 package and runs from the Windows command line. It takes an upper-case "-I" option. This ignores the "*.mpg" files...
Given those variations, piping the output of "ls" through "grep" may be a better, more universal solution.

That option is not available on my Mac either. I checked that also earlier as per some Google searches. I think it because Mac is not using GNU unix. I have had trouble before with the Mac Unix not being as flexible as GNU.

P.S. Those were both good suggestions and I found them also by doing a Google search. But they just don't work on the Mac. So I generally try to use solutions that work on my Mac, since they generally also work in other Linux systems.

"ls --include '*.mpg'" and "ls -I '*.mpg'" work fine on the ls that comes with Cygwin, on my Windows 8.1. It works both in bash, and from the Windows CMD prompt.
