Welcome to the forum.

If you want to use the command line argument like this, you have to pass the argument at the time of running the script. ( unlike prompting for it )
Code:
$ cat arg.sh
age=$1
echo "you are $age years old"
$ 
$ ./arg.sh 26
you are 26 years old
$ 
$ 
$ 
$ cat read.sh
echo -n "what is your age? "
read age
echo "you are $age years old"
$ 
$ 
$ ./read.sh
what is your age? 26
you are 26 years old
$ 
$

NAME
snexpire - expire news under the sn system. SYNOPSIS
snexpire [-v] [-exp] newsgroup [[-exp] newsgroup]... DESCRIPTION
snexpire expires news in the sn news system, one article file (=10 articles, compile time default) at a time. snexpire always leaves behind at least one article file, so that newly entered articles will have numbers not overlapping previously used numbers. As an excep- tion if the expiration age is set to 0, then even this last file will be expired and subsequent article numbers will start from the begin- ning. You will need to be root or own /var/spool/sn to run snexpire. OPTIONS
-v Output a line for each article expired. The format of this line is the same as for snscan. ARGUMENTS
snexpire expires all newsgroups named on the command line. Each newsgroup may be preceded by -exp to control the expiration age. exp is of the form #[hdwmy] where # is a number, followed by one of the characters h,d,w,m,y representing hours, days, weeks, months and years. The default for -exp is a compile-time fixed. Each [-exp] applies to the next newsgroup only, any newsgroups after that one get default treatment unless overridden by another [-exp]. FILES MODIFIED
/var/spool/sn/newsgroup/.times, /var/spool/sn/newsgroup/[0123456789]*, /var/spool/sn/{.chain,.table}. ENVIRONMENT VARIABLES
SNROOT If this is set and is not empty, the value is used in place of /var/spool/sn, the default news spool directory. FILES
/var/spool/sn/newsgroup/.expire If this exists, its contents are taken to be exp if not overridden by -exp on the command line. N.B. Harold Tay snexpire,v0.3.8(8)
