Please give us a clear specification of what you are trying to do, and tell us what operating system and shell you're using.
how do i print a specific number of spaces, which is equal to the number of characters in a name.

say a user specifies the name: check_disks.sh

there are 14 characters in the name "check_disks.sh".

i want to now print 14 spaces.

labelit_hsfs

labelit_hsfs(1M)					  System Administration Commands					  labelit_hsfs(1M)

NAME

       labelit_hsfs - provide and print labels for hsfs file systems

SYNOPSIS

       /usr/sbin/labelit -F hsfs [generic_options] [-o specific_options] special

DESCRIPTION

       labelit can be used to provide labels for unmounted CD-ROM images (CD-ROMs may not be labeled, as they are read-only media).

       generic_options are options supported by the generic  labelit command.

       If no specific_options are specified, labelit prints the current value of all label fields.

       The special name should be the physical disk section (for example, /dev/dsk/c0d0s6).

OPTIONS

       -o	Use one or more of the following  name=value pairs separated by commas (with no intervening spaces) to specify values for specific
		label fields. According to the ISO 9660 specification, only certain sets of characters may be used to fill in these labels.  Thus,
		``d-characters''  below  refers to the characters `A' through `Z', the digits `0' through `9', and the `_' (underscore) character.
		``a-characters'' below refers to `A' through `Z', `0' through `9', space, and the following characters: !"%&'()*+,-./:;<=>?_.

		absfile=	Abstract file identifier, d-characters, 37 characters maximum.

		applid= 	Application identifier, d-characters, 128 characters maximum.

		bibfile=	Bibliographic file identifier, d-characters, 37 characters maximum.

		copyfile=	Copyright file identifier, d-characters, 128 maximum.

		prepid= 	Data preparer identifier, d-characters, 128 maximum.

		pubid=		Publisher identifier, d-characters, 128 maximum.

		sysid=		System identifier, a-characters, 32 maximum.

		volid=		Volume identifier, d-characters, 32 maximum.

		volsetid=	Volume set identifier, d-characters, 128 maximum.
