as per my understanding if you are looking for multiple replacement and change in a single command this shall work
sed -e "s/cat/lion/g" -e "s/yes/no/g' -e 's/true/false/g' -e ....... -i.backup actual_file

will do all the replacement and keep a backup of your file, named actual_file.backup

offcourse its up to you, how good you are able to write the regular expression, more accurate less errors and surprises, but it will be fun, welcome to sed
its tricky first time, try to keep a backup manually :-)

backup_help

BACKUP_HELP(8)						       AFS Command Reference						    BACKUP_HELP(8)

NAME
       backup_help - Displays help for backup commands

SYNOPSIS
       backup help [-topic <help string>+] [-admin] [-help]

       backup h [-t <help string>+] [-a] [-h]

DESCRIPTION
       The backup help command displays the complete online help entry (short description and syntax statement) for each operation code specified
       by the -topic argument. If the -topic argument is omitted, the output includes the first line (name and short description) of the online
       help entry for every backup command.

       To list every backup command whose name or short description includes a specified keyword, use the backup apropos command.

OPTIONS
       -topic <help string>+
	   Indicates each command for which to display the complete online help entry. Omit the backup part of the command name, providing only
	   the operation code (for example, specify dump, not backup dump). If this argument is omitted, the output briefly describes every backup
	   command.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT
       The online help entry for each backup command consists of the following two or three lines:

       o   The first line names the command and briefly describes its function.

       o   The second line lists aliases for the command, if any.

       o   The final line, which begins with the string "Usage", lists the command's options in the prescribed order. Online help entries use the
	   same symbols (for example, brackets) as the reference pages in this document.

EXAMPLES
       The following example displays the online help entry for the backup dump command:

	  % backup help dump
	  backup dump: start dump
	  Usage: backup dump -volumeset <volume set name> -dump <dump level name>
	  [-portoffset <TC port offset>]  [-at <Date/time to start dump>+]
	  [-append]  [-n]  [-file <load file>]	[-help]

PRIVILEGE REQUIRED
       None
