vi

[Patrick Dupre]

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
