Store and run ex: commands in text fileWed 25 June 2014 by Mikhail Basov
It is possible to store any ex: commands in text file and then execute them.
For example. I want to periodically insert current content of some file in other text file.
Do the following:
- Put to file the following line
- Set cursor to this line an execute in command mode:
- The result is:
:r /etc/hosts 127.0.0.1 localhost 127.0.1.1 HOSTNAME # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
Put current line to buffer with name 'z'
Execute content of buffer 'z' as ex: command
Vim short form:
This command use unnamed buffer register. 'Y' put current string to unnamed register, @" execute content of unnamed register as ex: command. This operate only in Vim and doesn't operate in POSIX vi.
