File count script not working properly
Hi Experts,

I have this script to count the number of files based on prefix and suffix values.

Code:
#!/bin/ksh
file_date=$1
prefix=$2
suffix=$3
file_count=$(ls -l /db/day_file/{$prefix}*${file_date}*{$suffix})

The files in the directory /db/day_file are as below.

Code:
20170501
20170501
20170501.txt
20170501.txt
20170501.txt
abc_20170501.txt
abc_20170501
abc_20170502
20170502

Scenario1:If I pass the values as file_date=20170501 and prefix and suffix are empty.The script should give the count 2.
Since it should consider the files are 20170501 and 20170501.
But the script is not working properly.

Scenario2:If I pass the values as file_date=20170501 and prefix=abc_ and suffix is empty.The script should give the count 1.
Since it should consider the file abc_20170501
But the script is not working properly.

Scenario3:If I pass the values as file_date=20170501 and prefix is empty and suffix is .txt.The script should give the count 3.
Since it should consider the file 20170501.txt
But the script is not working properly.

Scenario4:If I pass the values as file_date=20170501 and prefix is abc_ and suffix is .txt.The script should give the count 1.
Since it should consider the file 20170501.txt
in this case the script is working properly.


Please help me.

Thanks in advance.

NAME

       trcs - convert text files from one codeset to other

SYNOPSIS

       trcs -C | -l | -h

       trcs [-s] [-f input-codeset ] [-t output-codeset ] [ file ]...

DESCRIPTION

       trcs  is a program for translation of text files from one codeset to other.  When exact translation is impossible it tries to make approxi-
       mations.  For example pseudographic characters are approximated by ASCII characters in codesets that have no pseudographic  characters  and
       characters with diacritical marks are approximated by existing characters.

       If the option -s or --gen-script is given trcs will generate simple script that invokes tr(1) This is useful if you want to include this in
       your script or for faster conversion of many files.

       If none of -C, -s, -l, -h and their equivalents is given each file will be read assuming it is coded with codeset input-codeset On standard
       output  it will be recoded so to use codeset output-codeset If there is no file given trcs will act as filter.  Both input-codeset and out-
       put-codeset are case insensitive and default to `cp1251'.

OPTIONS

       -C, --copyright
	      Display copying conditions and warranty information.

       -s, --gen-script
	      Generates conversion script for given input and output encodings instead to convert text files.

       -l, --list
	      List all known codesets with their aliases.

       -h, --help
	      Display this help and exit.

       -f input-codeset, --from[=]input-codeset
	      Codeset of the source.

       -f output-codeset, --to[=]output-codeset
	      Codeset of the output.

EXAMPLES

       trcs -fcyrillic -t koi8-r letter.txt
	      Convert letter.txt from ISO-8859-5 (cyrillic) to KOI8-R and output the result on standard output.

       trcs --from cp437 --to=mik --gen-script >ibm2mik
	      Generates script ibm2mik for converting from CP437 to MIK.

       sh ibm2mik screen.txt
	      Convert screen.txt from CP437 to MIK.  Output the result on standard output.  Without parameters ibm2mik acts as filter.
