# comment/uncomment the current command. This is something introduced by the Korn shell (ksh) in
|
|
# 1993. It allows you to capture a command in the shell history without executing it. Then
|
|
# retrieving the command from the shell history and removing the comment chars.
|
|
#
|
|
# This deliberately does not execute the command when removing the comment characters to give you an
|
|
# opportunity to modify the command. Also if the commandline is empty, the most recently commented
|
|
# out history item is uncommented and presented.
