It would be especially useful to review the manual pages or any documentation on the following resources:
Compression is a technique used to reduce file size.
The two types of compression are referred to as lossy and lossless. Lossy causes data to be lost during the compression process, while lossless techniques of compression allow original data to be reconstructed perfectly from the compressed data when the file is extracted.Hence the names lossy and lossless.
In the UNIX class Public Directory on lab46 you will find a dac0/ subdirectory. You can use the grabit command to get copy dac0/ to your present directory.
You can check the current repository status by using “hg status”
You can add untracked files to your repository by using the “hg add -I -a” command. -I for include pattern -a for “All untracked”
To commit a file, you must use hg commit [file1, file2,…] command with the files that you already added. It will take you to a screen similar to nano or pico editors. Once there you can type a name for your commit and then press enter to accept the name. It will ask if you are sure that you want to save it to a confusing looking name. Press enter and it will return you to the command line. Use hg status to see if you can see any files that you just tried to commit. If you don't see them than your commit will have been successful.
To get your commit actually committed you should use “hg push” to push the file along to be pulled at a later time.
You can pull changes from the server by using the “Hg pull” command.
