A Command to display a specific line??
 
Hello,
i'm new to linux, and i'm also taking a course on it, so i need some help :)

the question is: The file 'threelines' contains 3 lines of text. Display the middle line on the screen. You are not allowed to use the 'more' command.

try using a combination of head and tail

thank you.

Hi,

A few ways to do this. Here is one:

tail -2 <file> | line

Another way: number the lines with 'nl <file>' and use grep (nl <file> | grep -w 2).

With head and tail only:

tail -2 <file> | head -1

This is the question.

Search the file 'data' for all of the lines that contain the pattern 'uli101'and put those lines in the file 'matches'.

Any help would be appreciated. Thanks :)

gotten?
 
Got is already in past-tense there is no need for you to add the 'ten' at the end.
