bash – remove first line with tail and last line with head

You can achieve the same result with other (more powerful) tools, but I like this approach because it's the simplest I can think of.

Let's say you have this text file called test.txt

 
line 1
line 2
line 3
 

Remove the first line

 
tail -n +2 test.txt
line 2
line 3
 

Remove the last line

 
head -n -1 test.txt
line 1
line 2
 

I used them directly on a file but keep in mind that they can always be used in one-liners like:

 
cat test.txt|tail -n +2|head -n -1
line 2
 

Hope it helps!
