Not directly related to your question, but in bash / ksh93 / zsh, parameter expansion would be quicker and more efficient than using external programs to modify a variable..
If those boxes all contain such a shell then that might be a better option.

Code:
blah1=${blah// /|}
blah2=${blah1//_space_/ }
blah3=${blah2//_LP_/(}
blah4=${blah3//_RP_/)}
echo "$blah4"

If you need to repeat that same process in you script, you can also put it in a shell function


--
note: echo $blah should be : echo "$blah"
The quotes are to protect the content from field splitting and globbing by the shell

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
