Hello,
I would like to execute a vi command as a bash command like: vi +:1 "+1,$s/E/e/g" "+wq" test.TXT But it does not work!
under vi, I would do: vi test.TXT :1 :1,$s/E/e/g :wq
could you tell me what I am missing?
Thank

technically, I guess, based on the man page, it doesn't need to be, but you may want to try that (I assume that your VI is, in fact, VIM).

This is why you should always use single quotes (') instead of double quotes (") unless there is some reason not to, such as _wanting_ to substitute a shell variable into a string.
As an aside, is there a reason you want to use vi for this instead of something like sed?

Can I make 2 substitutions on a single call with sed?

Of course! You can write whole programs in sed. It is extremely useful.
sed -i s/E/e/g test.TXT
The -i is a GNU-sed extra for pretend in place editing; it makes a temp file with the changes then renames that to the original. That makes for an atomic change, but means the changed file is a new one, not a rewritten old one.
"sed" is short for stream editor, it normally lives in a shell pipeline to modify data passing through it. It has the ed command set plus some extra things.
Those edit commands you use after ":" in vim? They are based on the ed command set too.

Two or more ...
$ sed -i -e 's/E/e/g' -e 's/Alfa/xxxxxx/g' file.txt
No -e option is needed, since you can concatenate multiple expressions with a ';' character:
sed -i 's/E/e/g;s/Alfa/xxxxxx/g' file.txt
