How to extract work in line string.?

Hello all,

Soon I will be receiving a new file. I've asked the source system to put "TRAILER.1+0000007+1" for the trailer to indicate full receipt of file. I need to know how to separate TRAILER so I can use it in a if statement.

I used the tail command but not sure how to incorporate awk or sed. I just want to word TRAILER and I also want to separate 0000007 which is the file line count.

Code:
/xtimport/fi> tail -1 /xtimport/fi/FBOC810G* | awk '{print $1;}'
"TRAILER.1+0000007+1"

Try this...
Code:
tail -1 file | awk -F. '{sub("\"","");print $1}' | while read var; do
    if [ $var = "TRAILER" ]; do
       <do stuff here...>
    fi
done

This works perfectly. Can you help me understand this piece a little more for learning sake? Thanks much for all help.
Code:
awk -F. '{sub("\"","");print $1}'

This code didn't work. Can you help me understand from -F [\"\.]
Code:
tail -1 filename | awk -F[\"\.] '{print $1}'

Quote:
awk -F[\"\.]
- It mean input field separator either double quotes (") or dot (.)
Quote:
'{print $1}
' - Print field 1

Could you please post error which you are facing with the earlier solution ?

Its not printing TRAILER. No error.

Code:
$ ./james.sh
tail -1 FBOC810G_140305.CSV | awk -F["\.] '{print }'
