4.10.8 Using getline into a Variable from a Coprocess
When you use ‘command |& getline var
’, the output from the coprocess command
is sent through a two-way pipe to getline
and into the variable var
.
In this version of getline
, none of the predefined variables are changed and the record is not split into fields. The only variable changed is var
. However, RT
is set.
