In the KornShell (ksh) on AIX UNIX Version 5.3 with the editor mode set to vi using:
set -o vi
What are the key-strokes at the shell command line to autocomplete a file or directory name?
ESC\ works fine on AIX4.2 at least. One thing I noticed is that it only autocompletes to the unique part of the file name.
So if you have the files x.txt, x171go and x171stop, the following will happen:
Press keys: Command line is:
x x
<ESC>\ x
1 x1
<ESC>\ x171
g<ESC>\ x171go
