Rename file based on first 3 characters of data in file
I'm looking to determine if I can use a grep command to read file and rename the file based on the first 3 characters of the data in the file.
An example is:
Read FileA
If the first 3 positions of the data in the file are "ITP", then rename the file as FileA_ITP, else if the first 3 positions are "UNB" then rename the file FileA_UNB.
I believe I might be able to use the GREP command to identify the data but not sure how to rename the file being processed.
Appreciate any feedback.

lurename
lurename(1M) System Administration Commands lurename(1M)
NAME
lurename - change the name of a boot environment
SYNOPSIS
/usr/sbin/lurename -e BE_name -n new_name [-l error_log] [-o outfile] [-X]
DESCRIPTION
The lurename command is part of a suite of commands that make up the Live Upgrade feature of the Solaris operating environment. See
live_upgrade(5) for a description of the Live Upgrade feature.
The lurename command renames the boot environment (BE) BE_name to new_name.
The string new_name must not exceed 30 characters in length and must consist only of alphanumeric characters and other ASCII characters
that are not special to the Unix shell. See the "Quoting" section of sh(1). The BE name can contain only single-byte, 8-bit characters. It
cannot contain whitespace characters. Also, new_name must be unique on the system.
A BE must have the status "complete" before you rename it. Use lustatus(1M) to determine a BE's status. Also, you cannot rename a BE that
has file systems mounted with lumount(1M) or mount(1M).
Renaming a BE is often useful when you upgrade the BE from one Solaris release to another. For example, following an operating system
upgrade, you might rename the BE solaris7 to solaris8.
The lurename command requires root privileges.
OPTIONS
The lurename command has the options listed below.
-e BE_name Name of the BE whose name you want to change.
-l error_log Error and status messages are sent to error_log, in addition to where they are sent in your current environment.
-n new_name New name of the BE. new_name must be unique on a given system.
-o outfile All command output is sent to outfile, in addition to where it is sent in your current environment.
-X Enable XML output. Characteristics of XML are defined in DTD, in /usr/share/lib/xml/dtd/lu_cli.dtd.<num>, where
<num> is the version number of the DTD file.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/etc/lutab
list of BEs on the system
/usr/share/lib/xml/dtd/lu_cli.dtd.<num>
