Top Forums Shell Programming and Scripting case statement based on file availability Post 51748 by Loriel on Saturday 29th of May 2004 05:34:00 PM

Thanks for the example. I follow the logic for making a list of existing files, but it's the case statement that is confusing me. I'm not sure what to put in the 'options' section (talk about irony - that's where you stopped). This is the output (no options selectable):

1) This.txt
2) That.txt
#?

If I select either option, it returns Invalid Selection.

Here's the code I used:
Code:
i=0
for item in This.txt TheOther.txt That.txt
do
	if [ -r $item ]; then
		existing[i]=$item
		let i++
	fi
done

select readme in "${existing[@]}"
do
	case "$readme" in
		$existing[1])	echo "This.txt";;
		$existing[2])	echo "Red Herring";;
		$existing[3])	echo "That.txt";;
		*	)	echo "Invalid Selection";;
	esac
done

NAME

       dcentvfy - ACR/NEMA DICOM PS3 ... DICOM PS3 - Validate DICOM entities

SYNOPSIS

       dcentvfy " inputfile1 [ inputfile2 ... ]" [ -v|verbose|vv|veryverbose ] [ -f|-filelist  filename ]

DESCRIPTION

       dcentvfy  reads	the named dicom files (and/or the files listed in the specified file), extracts patient, study, series and instance entity
       unique identifiers and then validates that the attribute values defined in the standard for those entities have consistent values  for  the
       same entity.

OPTIONS

       The description and verbose output go to standard error.

       The basic input switches are described in dcintro(1). Options specific to this program are:

       -v|verbose
	      Describe as files are read and analyzed and the model of entity relationships to instances is built.

       -vv|veryverbose
	      Describe the detailed behavior of comparison of each attribute for each entity for each instance.

       -f|filelist filename
	      A file containing a list of DICOM input files (one filename per line).
