I recently starting using Clearcase for versioning, at work. I come from a CVS background, so initially found it to be cumbersome. For example, here is how i added a file to the repository:

CVS method:

<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> Change to your already checked out working folder<br /> cd /your/working/dir<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> list folder contents, will see checked out working files<br /> ls -l<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> List status of all the files, (optionally, update if needed)<br /> cvs -qn up<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> copy in new file to commit<br /> cp ~/yourfile.sh .<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> add file to repository<br /> cvs add yourfile.sh<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> commit changes, and make add permanent<br /> cvs commit -m "commit message"<br />

Clearcase method:

<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> Change to your pre-defined clearcase VOB top level folder (will be empty)<br /> cd /your/working/dir<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> set your view<br /> cleartool setview [viewname]<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> list folder contents, will see working files through "this view"<br /> ls -l<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> List status of all the files<br /> cleartool ls -l<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> Make current folder checked out for modifications, -nc means no comment<br /> cleartool co -nc .<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> copy in new file to commit<br /> cp ~/yourfile.sh<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> make new file a new element, and check it in (just like cvs add)<br /> ct mkelem -ci yourfile.sh -c "commit message"<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> check in current folder, as modifications are done, -nc means no comment<br /> cleartool ci -nc .<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> end your view. your folder is now empty<br /> cleartool endview [viewname]<br /> <a href="http://search.twitter.com/search?q=%23" class="tweet-hashtag">#</a> release your license (if needed)<br /> clearlicense -release<br />

See? CVS is simpler. But you have to work with what you have. I can see the benefit of Clearcase in a complex development environment. Expect to hear more from me on this tool from IBM.
