Find each occurrence of ‘foo’ (in all lines), and replace it with ‘bar’.

Method 1

:%s/foo/bar/g

Method 2

If you just want to delete all occurrences of “involve”, that is done with a standard vi command, e.g.,

:%s/\<involve\>//g

The markers \< and \> are used to ensure that you do not change words such as “involved”, “involvement”, etc.

Method 3

Try this search and replace:

:%s/foo/bar/gc

Change each ‘foo’ to ‘bar’, but ask for confirmation first.

Press y or n to change or keep your text.
