Name:_________________________________________

Paste your answser and pipeline.

What files in the filesystem whose names end in .txt are not
considered some kind of text by the file command?
How many are there?
Hints:
1. the files whose names contain .txt
2. reduce that to the files whose names end in .txt
3. file command them
4. reduce that to the non-text files
5. count them
Then, how many different kinds of files are those? Hint: cut, sort 


How many files or folders in the system have names that contain a space:
___________________________

Show the username, PID and TIME of the five processes in the system that have 
used the most TIME as reported by 'ps ax'.  
___________________________________________

PPID is the parent PID (viewable with the axl option of ps).  
Which process spawned the most number of child processes:
__________
How many did it spawn:_____________

Make a list of each process and the number of sub-processes it spawned.
hint: awk associative array to calculate frequency.

SKIP BELOW:
*************************
Do any of the Snn* symbolic links in the current runlevel's rc folder point to files
whose names are not the same as the * part of the Snn* symbolic link: 
_______________________________________________
in other words, does each filename in one directory exist in the other directory.
for i in `ls /etc/rc2.d/S* | sed 's?.*/S..??g'` ;do if ls /etc/init.d | grep  $i >/dev/null ;then : ;else echo Missing $i ;fi  ;done

In general, is one list a subset of another?  Make a pipeline that will test if every word
of one file is in another file.
____________________________________________

Make a pipeline that determines if there are any copies of a file in some 
particular folder.
