It depends on how fancy you want it. Like penchal said you could have echo statements.
Code:
#!/bin/bash
file=$1
echo "Info: Displaying file $file"
cat $file

Run that as...
Code:
./script test.txt >> test.log

Some scripts do this...
Code:
#!/bin/bash
file=$1
log=$2
echo "Info: Displaying file $file" >> $log
cat $file

Run that as...
Code:
./script test.txt test.log

A better way is to use 'getopt' or builtin 'getopts' then you could put an optional '-l test.log' on the command line, which would be more clear. Even fancier is to set a loglevel of verbosity. People do that with '-v' multiple times or '-v LEVEL' where LEVEL is optional. Let me know if more examples are needed.

NAME

       Log, .Log - Contains the uucp program log files

SYNOPSIS

       /usr/spool/uucp/.Log

DESCRIPTION

       The /usr/spool/uucp/.Log directories contain uucp program log files.  The uucp program normally places status information about each trans-
       action in the appropriate log file each time you use the networking utilities facility.	All transactions of the uucico and  uuxqt  daemons
       are  logged  in	files named for the remote system concerned.  The files are stored in a subdirectory of the /usr/spool/uucp/.Log directory
       named for the daemon involved.  Thus, the log files are named with a form of the following: /usr/spool/uucp/.Log/DaemonName/SystemName

       The uucp and uuto commands call the uucico daemon.  The uucico daemon activities for a particular remote system are logged in  the  System-
       Name file in the /usr/spool/uucp/.Log/uucico directory on the local system.

       The uux and uusend commands call the uuxqt daemon.  The uuxqt daemon activities for a particular remote system are logged in the SystemName
       file in the /usr/spool/uucp/.Log/uuxqt directory on the local system.

       When more than one uucp process is running, however, the system cannot access the standard log file, so it places the status information in
       a file with a .Log prefix that covers just the single transaction.

       The  uucp  program can automatically append the temporary log files to a primary log file.  This is called compacting the log files, and is
       handled by the uudemon.cleanu command, a shell procedure, which combines the log files of the activities of the uucico and uuxqt daemons on
       a system and stores them in the /usr/spool/uucp/.Old directory.

       The  default  is for the uudemon.cleanu command to save log files that are 2 days old.  This default can be changed by modifying the appro-
       priate line in the shell script.  If storage space is a problem on a particular system, reduce the number of days that the files  are  kept
       in the individual log files.

       The uulog command can be used to view the uucp program log files.
