1. ps | sort -r +4

2. grep a /usr/share/dict/words | grep b | grep c | grep d | grep e |
   grep -c f

3.  yes "1 0" | fmt -w 15 | head -n 7

4. ls -l /etc/*.conf | sort -r +4 | head -n 5

5. 'ls > temp; head -1 < temp' requires that a 'temp' file can be
   created in the current working directory. If permissions prevent
   this, then the command will not work. Worse, if there is already a
   'temp' file, it will be overwritten.

6. temp4 contains:
     y
     y
     n
     n
   This is what we expect, since (myyes & myyes) runs both processes
   at the same time, while (myyes ; myyes) waits for the first
   process to finish before starting the second.

7. ~ 30 min
