Im trying to write a bash script that has an if statment that when the user enters ONLY that exact argument, will echo what follows that conditon.
For example:
Basically, if i specify anything other then 1 as this cmd files argument, it wont output anything.
But if i do specify 1 it will output the value that Var1 is holding... Another problem tha t i was having is that it will output when any 1 argument is passed. For example if 2 arguments are passed it wont output anything. If no arguments are passed it wont output anything. But it really doesnt matter what 1 argument i specify, it will output as long as 1 argument is givin.
What im trying to figure out from that point is how to write an if statement that looks for an exact match of that 1 argument that the user would specify.
Can someone please help me with this SHELL script?
I need to create a script that gets a positive number n as an argument. The script must calculate the factorial of its argument. In other words, it must calculate n!=1x2x3x...xn. Note that 0!=1.

cat
cat(1) General Commands Manual cat(1)Name
cat - concatenate and print data
Syntax
cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...
Description
The command reads each file in sequence and displays it on the standard output. Therefore, to display the file on the standard output you
type:
cat file
To concatenate two files and place the result on the third you type:
cat file1 file2 > file3
To concatenate two files and append them to a third you type:
cat file1 file2 >> file3
If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file. Output is buffered in
1024-byte blocks unless the standard output is a terminal, in which case it is line buffered. The utility supports the processing of 8-bit
characters.
Options-b Ignores blank lines and precedes each output line with its line number.
-e Displays a dollar sign ($) at the end of each output line.
-n Precedes all output lines (including blank lines) with line numbers.
-s Squeezes adjacent blank lines from output and single spaces output.
-t Displays non-printing characters (including tabs) in output. In addition to those representations used with the -v option, all tab
characters are displayed as ^I.
-u Unbuffers output.
-v Displays non-printing characters (excluding tabs and newline) as the ^x. If the character is in the range octal 0177 to octal 0241,
it is displayed as M-x. The delete character (octal 0177) displays as ^?. For example, is displayed as ^X.
