Insert shell command into first line of output file
How can I insert the command executed on the shell into the first line of my output file?

zcat *.gz |grep “User5501” > users.out

Code:
zcat *.gz |grep “User5501” > users.out
User5501 PA
User5501 UA
User5501 ZA
User5501 NU
User5501 NA
User5501 RU

chsh

chsh(1) 						      General Commands Manual							   chsh(1)

NAME

       chsh - change default login shell

SYNOPSIS

       login-name [shell]

       login-name [shell]

       login-name [shell]

       login-name [shell]

DESCRIPTION

       The command changes the login-shell for a user's login name in the repository (see passwd(1)).

       The  DCE  repository is only available if Integrated Login has been configured; see auth.adm(1M).  If Integrated Login has been configured,
       other considerations apply.  A user with appropriate DCE privileges is capable of modifying a user's shell;  this  is  not  dependent  upon
       superuser privileges.

       If the repository is not specified (as in [login-name]), the login shell is changed in the file only.

       Run after running to make sure the information was processed correctly.

   Notes
       The  command  is  a hard link to the command. When is executed, actually the command gets executed with appropriate arguments to change the
       user login shell in the repository specified in command line. If no repository is specified, the login shell is changed in the file.

   Arguments
	      login-name  A login name of a user.

	      shell	  The absolute path name of a shell.  If the file exists, the new login shell must be listed in that file.  Otherwise, you
			  can specify one of the standard shells listed in the getusershell(3C) manual entry.  If shell is omitted, it defaults to
			  the POSIX shell,

   Options
       The following option is recognized:

	      Specify the repository to which the operation is to be applied.
		     Supported repositories include and

   Security Restrictions
       You must have appropriate privileges to use the optional login-name argument to change another user's login shell.

NETWORKING FEATURES

   NFS
       File can be implemented as a Network Information Service (NIS) database.

EXAMPLES

       To change the login shell for user to the default:

       To change the login shell for user to the C shell:

       To change the login shell for user to the Korn shell in the DCE registry:

WARNINGS

       If two or more users try to write the file at the same time, a passwd locking mechanism was devised.  If this locking  fails  after  subse-
       quent retrying, terminates.

AUTHOR

       was developed by HP and the University of California, Berkeley.
