Spawing multiple display processes from one shell.
Question: Suppose I want to, from the terminal, use a shell script that would do the display image.jpg command to load multiple images from a directory all at the same time. One terminal, and for example 10 image files. Basically I want to execute 10 different commands simultaniously all from the same shell and open ten different windows with the images in them.

How would this be done?

I have a basic idea with for loops, number sequences, and background processes. But is there an easy way that's pretty much universal on any unix platform?

for file in `ls -1 *.jpg`; do display $file; done

does a nice job of displaying the images in alphabetic order one by one. but I want to load em all up all at the same time from one shell.

igrep

IGREP(1)						      General Commands Manual							  IGREP(1)

NAME

       igrep - search images for matching metadata

SYNOPSIS

       igrep [options] pattern files...

DESCRIPTION

       The igrep utility is invoked as follows:

       igrep [options] pattern filename...

       Where  pattern  is  a POSIX.2 regular expression (just like the Unix/Linux grep(1) command), and filename (and any following names) specify
       images or directories that should be searched. An image file will "match" if any of its metadata contains values contain substring that are
       recognized  regular  expression.  The  image  files  may be of any format recognized by OpenImageIO (i.e., for which ImageInput plugins are
       available).

       Example:

       $ igrep Jack *.jpg
       bar.jpg: Keywords = Carly; Jack
       foo.jpg: Keywords = Jack
       test7.jpg: ImageDescription = Jack on vacation

       For a complete description, see /usr/share/doc/libopenimageio-dev/openimageio.pdf.gz.

OPTIONS

       --help Print help message

       -i     Ignore upper/lower case distinctions

       -v     Invert match (select non-matching files)

       -E     Pattern is an extended regular expression

       -f     Match against file name as well as metadata

       -l     List the matching files (no detail)

       -r     Recurse into directories

       -d     Print directories (when recursive)

       -a     Search all subimages of each file
