Shell Scripting Question
To anyone who can help greetings,
I am a beginner at Unix shell scripting and am taking a class.
The assignment question is as follows:

use a command-line tool named "itstat" which will display the resolution of an image file and some other lines of information. It accepts a list of image files as arguments (i.e., "itstat FILE1 FILE2 ..."), and its output looks like this:
File: pet_mocap_comp_v1_tvfa_vd8.1713.jpg
Resolution: 720 x 547
Channels: 3
Channel Types: RGB without Alpha Bit
Depth: 8
You are in a directory with 50 randomly named and sized images, and you want to know quickly the resolution of each file. Write a script that takes no arguments and uses itstat to print the filename and resolution of each file in the current working directory in the following format:
g50_comp_v6_2kfa_lg10.0310.rla: 2048 x 1556 g50_comp_v6_2kfa_lg10.0610.rla: 2048 x 1556 g50_comp_v6_2kfa_lg10.0710.rla: 2048 x 1556


I cannot find the commandline tool "itstat" and therefore do not know how to create a proper script.

Any assistance will be greatly appreciated.

pbmtextps

pbmtextps(1)						      General Commands Manual						      pbmtextps(1)

NAME

       pbmtextps - render text into a bitmap via postscript

SYNOPSIS

       pbmtextps [-font fontfile] [-fontsize fontsize] [-resolution resolution] [-stroke strokesize] [-verbose [text]

DESCRIPTION

       pbmtextps takes a single line of text from the command line and renders it into a PBM image.

       The  image  is cropped at the top and the right. It is not cropped at the left or bottom so that the text begins at the same position rela-
       tive to the origin. You can use pnmcrop to crop it all the way.

OPTIONS

       -font  By default, pbmtextps uses TimesRoman.  You can specify the font to use with the -font option. This is the name of any  valid  post-
	      script font which is installed on your system.

       -fontsize
	      Size of font in points. See the -resolution option for information on how to interpret this size.

	      Default is 24 points.

       -resolution
	      Resolution in dots per inch of distance measurements pertaining to generation of the image. PBM images don't have any inherent reso-
	      lution, so a distance such as "1 inch" doesn't mean anything unless you separately specify what  resolution  you're  talking  about.
	      That's what this option does.

	      In  particular,  the  meaning of the font size is determined by this resolution. If the font size is 24 points and the resolution is
	      150 dpi, then the font size is 50 pixels.

	      Default is 150 dpi.

       -stroke
	      Width of line to use for stroke font. There is no default stroke width because the letters are solid by default.

USAGE

       See pbmtext for usage examples.
