Creating a two page tiff document.

This is a follow up to a discussion from 2423 namely:  Creating a two page tiff document. - Apple Community

Back in 2423 I was successful at merging two tif files after VikingOSX guided me through a solution to my problem.  However, I failed recently.  I am 87 and my computer skills are rusty.  I am now on a new Mac mini M2 15.1.1.  I created the folder MacIntosh HD/User/robertdavis/Desktop/Experiment and placed two tiff images in it, namely 01.tiff and 02.tiff.  The two images were scanned using a CanoScan 8800F scanner and VueScan 9 a64 (9.8.41).  It is the same scanner that I used in 2423 but the VueScan is a fairly recently updated version.

This is the computer structure.

I ran this script with this result:

/usr/bin/tiffutil -cat *.tif -out multi.tif

cd: no such file or directory: User/robertdavis/Desktop/Experiment

zsh: no matches found: *.tif

After examining the manual that showed up on one of the runs 

TIFFUTIL(1)                 General Commands Manual                TIFFUTIL(1)

NAME

     tiffutil - manipulates tiff files

SYNOPSIS

     tiffutil <option> [<arguments>] [-out <outfile>]

DESCRIPTION

     tiffutil lets you manipulate TIFF files. The list of options (also

     available by running the program without any options) follows:

     tiffutil -none             infile                  [-out outfile]

              -lzw              infile                  [-out outfile]

              -packbits         infile                  [-out outfile]

              -cat              infile1 [infile2 ...]   [-out outfile]

              -catnosizecheck   infile1 [infile2 ...]   [-out outfile]

              -cathidpicheck    infile1 [infile2 ...]   [-out outfile]

              -extract          num infile              [-out outfile]

              -info             infile

              -verboseinfo      infile

              -dump             infile

I tried a different script with this result:

robertdavis@fiber-222 ~ % cd User/robertdavis/Desktop/Experiment

/usr/bin/tiffutil -cat 01.tif 02.tif -out multi.tif

cd: no such file or directory: User/robertdavis/Desktop/Experiment

Error: Failed to create image source for file 01.tif. Either it isn't a TIFF file, or there are unrecognized tags; try tiffutil -dump for more info.

Error: Failed to create image source for file 02.tif. Either it isn't a TIFF file, or there are unrecognized tags; try tiffutil -dump for more info.

Error: Can't read from file 01.tif.

No output file created due to errors.

After reading “dialabrains commentL

FWIW, /usr/bin/tiffutil -cat *.tif -out multi.tif doesn't work. Your original command tiffutil -cat *.tiff -out multi.tiff does

I tried this script after renaming the files 01.tiff and 02.tiff:

/usr/bin/tiffutil -cat *.tiff -out multi.tiff

cd: no such file or directory: User/robertdavis/Desktop/Experiment

zsh: no matches found: *.tiff

What am I doing wrong?  I am sorry for the length of this post but I hope it will save the multiple steps it took back in 2423.
