| 1. -n has the effect it has because it gives us a numbered list as the output | ||
| 2. wc -l < mydata.dat reads the input of the contents of the file "mydata.dat" and gives a list, whereas wc -l mydata.dat gives a list from the file itself and goes straight to the screen. | ||
| 3. "sort" is another command that can pipe with the "uniq" command. | ||
| 4. To be honest, I'm a little confused about this one. I took "cat animals.txt | head -5 | tail -3 | sort -r > final.txt" and substituted "cubane.pdb" for "animals.txt" and "final.pdb" for "final.txt", the last of which was probably not necessary...but oh well. The output was <imgur screenshot file> So, from what I got, it took the first three lines and outputted them in reverse order. So the head -5 part is still a little weird to me... |
