[NCLUG] tar

[Bill Thorson]

What Aaron said; and these points:
     1) the -v in your tar arguments turns on the "verbose" listing. 
(See 'man tar' again)
     2) Avoid the use of the asterisk in your echo statements. This is a 
wildcard to list all the files in your current directory. You are seeing 
things you didn't want.
     3) The cd /root at the end doesn't do anything for you.  When the 
script ends you will be back where you started with or without this.
