obviously, this is very inefficient.
i know i can combine into one sed command with something this, using a semi colon:
Code:
sed 's/|/=0,--/g ; s/$/=0/g'

unfortunately, this combining of commands in sed is not available on all unix oses. it bails on systems like AIX. i'm looking for a awk solution that would work on any UNIX os it is run on.
any ideas?
Hello SkySmart,

As you haven't shown the sample Input_file with expected output so by analyzing your code only I am providing the following solution, please do let me know how it goes on same.
Code:
awk '{gsub(/[[:space:]]/,"|",$0);gsub("_space_"," ",$0);gsub("_LP_","(",$0);gsub("_RP_",")",$0);print}' Input_file

Off course I haven't tested it as Input_file is not shown. Please let me know in case this doesn't meet your requirement with sample Input_file and expected output too, I hope this helps.

Thanks,
R. Singh
