Removing trailing characters
I have been given a shell script that I need to amend. To do the following
extract the filename from the flag file by removing the .flag extension.
Code:
# Local variables
# Find if the flag files exists
MASK=coda_mil2*.flag
 
# Are there any files?
    bookmark="40"
    fileFound=0
    ls -1 $MASK > /dev/null 2>&1
    if [ $? -eq 0 ]
    then
        # Oldest file
        bookmark="50"
        fileName=$( ls -1 $MASK | head -n 1 )
        # Extract the coda file name

Code:
   fileNameCoda=$( echo $fileName | cut -f1-2 -d. ) ????????

It is this line I am struggling with I need to remove the file extension from the flag file to get the actual file name that I am going to process with SQL Loader further down the script this would be fine if the two files looked like this

myfile.flag
myfile

But my files look like this
myfile.001.002.flag
myfile.001.002
It is this string that I am trying to get "myfile.001.002"

What could I do to extract the filename when it has multiple dot?

Code:
 fileNameCoda=$( echo $fileName | cut -f1-2 -d. )

With this I get myfile not myfile.001.002

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
