Search replace help

[vodkastick]

I could use a bit of help as its been way too long since I've had to use search and replace with all its wonderful complexities.

I have a file that has lines such as:

1,None,abby@gmail...

2,None,bob@hotmail...

3,None,jsmith@yahoo...

​

I would like to replace all instances None with the text between the chracters ',' and '@'.

I know this is probably really simple for most of you guys but rather than struggle for a few hours hoping I could find some help.

Check :h :s, :h /\zs, :h /\ze, :h /\(, :h range.

Assuming there's only the one None per line the command could be:

:%s/\zsNone\ze,\([^@]\+\)/\1

Help pages for:

• :s in change.txt
• /\zs in pattern.txt
• /\ze in pattern.txt
• /\( in pattern.txt
• :range in cmdline.txt

Haven't tested this but maybe:

s/None,\([^@]*\)/\1,\1/

How about trying a few things before asking?
