Opus (a RHEL server)

We will copy our work on Opus to a Windows PC

Then copy from there to a Linux virtual machine

Use find to list the files in bin/, answers/, and your /home directory used in this class.

These are the files we will archive and copy to another computer.

Starting in the CIS 90 class directory on Opus


CIS 90 - Lesson 15

/

/home/cis90 $ find bin/ answers/ roddyduk/ | wc -l263/home/cis90 $

Use wc to count the number of files in the three directories

13

The bin directory has allscripts, riddles and other files used in class. The answers directory has answers for each lab. Your home directory has all the files you made during the course.

Next, compress the archive with gzip

16

Note: gzip renames the tarball by adding the .gz suffix

CIS 90 - Lesson 15

Class ExerciseArchive your work on Opus

cd /home/cis90/

find bin/ answers/ $LOGNAME/ | wc -l

tar cvf /home/cis90/$LOGNAME/$LOGNAME.tar bin/ answers/ $LOGNAME/

tar tvf /home/cis90/$LOGNAME/$LOGNAME.tar | wc –l

cd

gzip $LOGNAME.tar

17

Archive everything in your home directory (including all sub directories) plus the class bin and answer directories into one tarball.

Now compress that tarball

Count the files to be archived

This counts the files in the archive
