How to use SED command(s) that will replace the shell's pipe command in
order to perform more efficient, e.g:
echo abcde | sed -r 's/cd/XX/' | sed 's/[^x]/z/ig'
become far more efficient and compact, might be look like this,
echo abcde | sed -r 's/cd/XX/ {N: s/ ........... }
( ...so on. That's what I am asking for )
both will give the same result zzXXz
The portable way is to use multiple "-e" parameters:
$ echo abcde | sed -e 's/cd/XX/' -e 's/[^x]/z/ig'
zzXXzz
That should work on all sed, not just gnu sed.
When using GNU sed, you can specify multiple commands
separated by semicolons:
$ echo abcde | sed 's/cd/XX/ ; s/[^x]/z/ig'
zzXXzz
I'm closing this item but discussion can continue by replying
