Unediting a commited file


From: Kayed Alfi

All:

I have an issue of unediting a file that has been
committed to the repository from the workspace.  I
tried to execute the following command:

cvs unedit "Training in CVS.xls

But it didn't put the file in "unedit" mode.  It stcuk
in edit.  I ran update, and queried the file, but to
no avail.

The reason I want to put it in an "Unedit" mode is to
place a "lock" on the file.  And, so long the file is
in "edit" mode it is not allowing me to lock the file?


The environment:  Client server vonfiguration with
pserver authontication mode.  I habve CVS 1.10 version
on my server.
