echo $stuff

However, I need to be able to get that line of text out of a text file rather than being in a variable, and I cannot for the life of me figure out how to do it.

Can anyone please help?

Thanks.
you mean you have that line in a file and you want to extract that line from a file??
or
you want to extract that line and from that line you want only string with @LOCALDOMAIN??

NAME
gencat -- NLS catalog compiler SYNOPSIS
gencat output-file input-files... DESCRIPTION
The gencat utility merges the text NLS input files input-files... into a formatted message catalog file output-file. The file output-file will be created if it does not already exist. If output-file does exist, its messages will be included in the new output-file. If set and message numbers collide, the new message text defined in input-files... will replace the old message text currently contained in output-file. INPUT FILES
The format of a message text source file is defined below. Note that the fields of a message text source line are separated by a single space character: any other space characters are considered to be part of the field contents. $set n comment This line specifies the set identifier of the following messages until the next $set or end-of-file appears. The argument n is the set identifier which is defined as a number in the range [1, (NL_SETMAX)]. Set identifiers must occur in ascending order within a single source file, but need not be contiguous. Any string following a space following the set identifier is treated as a comment. If no $set directive is specified in a given source file, all messages will be located in the default message set NL_SETD. $del n comment This line deletes messages from set n from a message catalog. The n specifies a set number. Any string following a space following the set number is treated as a comment. $ comment A line beginning with $ followed by a space is treated as a comment. m message-text A message line consists of a message identifier m in the range [1, (NL_MSGMAX)]. The message-text is stored in the message catalog with the set identifier specified by the last $set directive, and the message identifier m. If the message-text is empty, and there is a space character following the message identifier, an empty string is stored in the message catalog. If the message-text is empty, and if there is no space character following the message identifier, then the existing message in the current set with the specified message identifier is deleted from the catalog. Message identifiers must be in ascending order within a single set, but need not be contiguous. The message-text length must be in the range [0, (NL_TEXTMAX)]. $quote c This line specifies an optional quote character c which can be used to surround message-text so that trailing space or empty messages are visible in message source files. By default, or if an empty $quote directive is specified, no quoting of message-text will be rec- ognized. Empty lines in message source files are ignored. The effect of lines beginning with any character other than those described above is unde- fined. Text strings can contain the following special characters and escape sequences. In addition, if a quote character is defined, it may be escaped as well to embed a literal quote character. line feed horizontal tab v vertical tab  backspace carriage return f form feed \ backslash ooo octal number in the range [000, 377] A backslash character immediately before the end of the line in a file is used to continue the line onto the next line, e.g.: 1 This line is continued on this line. If the character following the backslash is not one of those specified, the backslash is ignored. DIAGNOSTICS
The gencat utility exits 0 on success, and >0 if an error occurs. SEE ALSO
catclose(3), catgets(3), catopen(3) STANDARDS
The gencat utility is compliant with the X/Open Portability Guide Issue 4 (``XPG4'') standard. AUTHORS
