If you want to make sure there is only one value printed (like a implicit |uniq) you need to quit after the first match:
This will print the first line starting with "Rows:" and leave sed after printing it. I have tried to improve the regexp so that (variable numbers of) blanks before and behind the number eventually get deleted too.
why i can't use this command:
echo $arg | cut -c 1,2 | read remainArg or
echo $arg | cut -c 1,2 | read $remainArg
so that the result will be assign to remainArg.
Anyway to do this? :) (1 Reply)

DCKEY(1) DICOM PS3 - Extract attribute values DCKEY(1)NAME
dckey - ACR/NEMA DICOM PS3 ... Extract attribute values
SYNOPSIS
dckey [ -ignorereaderrors ] [ -v|verbose ] [ -filename ] [ -describe ] [ -brief ] [ -d|decimal ] [ -key|k elementname|(0xgggg,0xeeee) ]
...
DESCRIPTION
dckey reads the named dicom input file and displays the values of the selected attributes.
Binary attributes are written in hexadecimal with a preceding "0x" and numeric string attributes are written in decimal as they are
encoded, unless the -decimal option is specified.
OPTIONS
The attribute values, description and verbose output go to standard error.
The basic input switches are described in dcintro(1). Options specific to this program are:
-describe
Display the tag, name, value representation and value length of the attribute.
-brief
Display the keyword of the attribute, and equals sign, and then the value, for use in scripts that automatically extract multiple
values in the same dckey invocation. Implies -noerror.
-ignorereaderrors
Attempt to extract key values even if errors encountered whilst parsing DICOM file.
-noerror
Do not report an error if the requested attribute was not found, just an empty value or line. Implied by -brief.
-d|decimal
Display the first (or only) value of a numeric attribute as a decimal value.
-k|key elementname|(0xgggg,0xeeee)
Add a key to the list of attributes to be extracted. The attribute may also be specified as a hexadecimal pair of the form
(0xgggg,0xeeee), which also allows private attributes to be fetched.
-filename
Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied.
ENVIRONMENT EXAMPLES
% dckey -key Rows -key Columns -key ImageLocation
-describe test.dc3

BUGS
Attempts to extract sequences or OB,OW attributes may fail nastily.
The order in which the attributes are extracted and written is not the same order as they are specified on the command line, and should not
be depended on.
The -describe and other options cannot be used at the same time.
The -decimal option uses a double conversion before displaying the value and there may be sign extension and precision issues with some
values.
The reading of the attributes from the DICOM file will not proceed past the top level Pixel Data attribute, in order to accelerate the
speed of reading.
