Hi!
Seems you live in the Windows World.
The line
ExecuteRead('/usr/sbin/ip',['-4', 'a'],sl);
means on the command line
/usr/sbin/ip -4 a
A WinDOS example: list a directory with subdirectories.
You do:
DIR /S
With my ExecuteRead you would do
ExecuteRead('DIR', ['/S'], sl);
And in the StringList
sl is the complete contents of the listed directory.
Got it?
