Hi, I know that this has been discussed again but I am still wondering how to get a line from a file.
I have a file named test.txt:
user:hello
profile:blue
color:blue
true:0
false:1
What is the command to read the line 3 (color:blue) ?????

I think it can be achieved using many ways like


# print line number 52
sed -n '52p' # method 1
sed '52!d' # method 2
sed '52q;d' # method 3, efficient on large files

from http://www.linuxquestions.org/questions/linux-software-2/sed-display-text-on-specific-line-of-text-file-397405/

Also I think some like this (not tested and ugly)
cat file | awk 'NR>2 && NR<4{print $0}'

Also you can play with head and tail, etc.

My friend I have to tell you that the last was the best solution!
