I think  AWK is hard to do about thouthands 'find/replace' for a huge
text in global range ....

  How about the 'perl' ?  which can open one any size file and read
into the memory for processing....

It depends on what awk it is.  gawk can reach the limitation of file system.  Why don't you test it?

Awk is same as sed to process file line by line. In general,  awk
is much faster than sed due to DFA instead of NFA algorithm.

Perl is also a good choice.
