Power How to write shell script for input file name format checking?


I had written a shell script that accepts input file as cmd line argument and process this file.
if [ $# -eq 1 ]; then
if [ -f $1 ]; then  
 . $1   
 error "$ERROR_CODE : Input file $1 is not available";  
 exit 1
 echo "usage : $usage";

I want a help in writting a get_input_file function which checks for file name format.
My input file name format is MIG_CR_<TYPE>_<TIMESTAMP>.<EXT>
FILE = '$1'
#checking file exist or not
if [ ! -f $FILE ]; then   
 echo "$FILE : does not exists"  
 exit 1
elif [ ! -r $FILE ]; then   
 echo "$FILE: can not read"   
 exit 2
// check file name format is correct or not

Can anyone tell me how can I check the format of file name?
Please help me out. Thanks in advance. Image

In the format MIG_CR_<TYPE>_<TIMESTAMP>.<EXT>
What do <TYPE> <TIMESTAMP> and <EXT> look like?
in other words, what are the authorized values of those substrings?

Thanks for reply.
Here are values,
TIMESTAMP = yyyymmddhhmmss (20100903040506)
EXT = CSV / zip / gz
