define a KeyMap which combines two command

[Steven Woody]

Hi,

I know use '|' and combine two command, but I don't know how to do
the combination when the first command is a external shell command
(prefixed by a '!').

For example, I want to define <F5> to run a shell command which
updates my cscope database and then run ':cs reset', I tried

nmap <F5> :!./recs-sh | :cs reset<CR>

but it failed.

Anyone can be kindly help?

The :execute command can help here.

nmap <F5> :exe '!./recs-sh' | cs reset<CR>

Note that the colon is needed only at the start of the command line,
not in front of each command.

See

:help :exe

Regards,
Gary

it's also possible to put <CR> between the commands. Then the colon is
needed with the second command:

nmap <F5> :!./recs-sh<CR>:cs reset<CR>

Thank you! It is a rescue.

Normally, the | character terminates the ":map" command. To use it in a
{rhs}, use <Bar> instead.

Best regards,
Tony.
