When I have some time, I will test out your suggestion.
Right now, we are just trying to find a quick solution - we are going live in a few weeks.
Thanks.
Never mind. My intuition was off. At least on OS X 10.10.4 on a 2 year old MacBook Pro with abc.txt containing about 4k lines and abc.sed containing 144 substitutions, sed averaged about .07 seconds, ex averaged about .11 seconds and ed took about .45 seconds. Your mileage may vary with different data, different hardware, and/or a different OS. If you want to try the script I used to convert abc.sed to an equivalent abc.ed and time sed and ed, it is at the end of this script. The abc.ed script it produces will work with both ed and ex. (Note that it was only tested with alphanumeric BREs in the sed substitute commands. Further work may be required if BRE special characters (especially /) or commas are included in the BREs in abc.se.
I did some benchmarks, too.
With sed the runtime grows exponentionally with abc.sed.
GNU sed, when abc.sed is >90 lines, is already slower than the perl solution in post#2.
For my tests I have embedded the perl code in a shell script, so it can read from a pipe or from an argument, just like sed.
