cvs

set cvsroot:

export CVSROOT=:pserver:andy@10.1.1.1:/home/cvs

login

cvs  login

import:

cvs  import  test andy ver1

test: project name on cvs server

andy:  Vendor-tag

ver1:  Version-tag

checkout:

get specific version:

cvs co -r  v1_2   projectName

get specific date:

cvs co -D "12/02/2008 13:00" projectName

get specific branch

cvs co -r branch_name  projectName

show status:

ex:

cvs st test.c

commit:

cvs commit  test.c

remove

1. rm test.c

2. cvs rmove teset.c

3. cvs commit test.c

when check out project next time, test.c is not checked out

but test.c is still on cvs server

Hence, we can roll back  the time test.c exists

svn

svn on windows: tortoiseSVN


一般分三種directories

trunk: 最新的程式

branch: 程式某個版本的branch，不會影響到最新的程式

tag: 每個release的程式，會有個tag對應，如此可以取回任何一版release的程式

將程式抓下來:

ex: svn checkout http://svn.techno-weenie.net/projects/plugins/acts_as_authenticated/
