Lab covering Ch5 Redirection. 10 points

Critical Skills:
Using Redirection in a realistic manner
redirecting stdin on at least one utility
copying a file and using chmod a file so that I can read it
using vi to edit a file
getting the file name correct and in the right place.




Log into shaula and practice redirection using your utilities that you already
know.




Here are some examples:
ls -l >file   (sends a long listing of a directories contents to "file")
ls -l |grep lab >file   (long listing is piped to grep and any file that
			is found with "lab" in the title is redirected
			to "file")
mail -s "test redirstdin" your_netid@shaula.csit.parkland.edu <file
			(Try the mail command first without the redirecting
			stdin, then mail yourself a file and see how good
			and easy it is to redirect stdin. Be sure that
			you redirect at least one stdin and mail is the
			best one to practice that on. (remember you can
			use either pine or mail to check your mail on the 
			system)
			(for some reason this only works from shaula
			to shaula)




Here are some others to try, use your own data:

./lab1.sh >finger_thurs_2_7_08
cat poem >redirected_poem
mail -s passwd smauney@csit.parkland.edu </etc/passwd
ls -l file |wc
ls -l file |wc -l
ls -l file |wc -l >howmany_files
ls -l file |wc -l >howmany_files
ls -l |grep file
ls -l |grep file |wc
ls -l |grep file |wc -l >>howmany_files
llllls 2>errors
ls -l |grep poem
ls -l |grep poem
ls -li |grep poem
ls |grep poem
ls |grep lab
ls |grep lab |less
./first.sh 1>first_output 
./first.sh >first_output 2>&1   (see p. 309 on stdout and stderr
				basically you stick stdout and stderr
				together using 2>&1 and then you 
				redirect both to a file at the same time.)


Once you have tested at LEAST 25 different redirections you will then
logout, log back in and copy your .bash_history to a file in your 
home directory called "redirection_lab.txt" (no quotes please)

Then chmod that file 644 so that I can get into it, and edit the file
so that all that it contains is the commands that you ran that use redirection
just like I did above. I'll grep around in that file to see if you have
practiced redirection etc.
