This post get top/bottom 10 from the sorted file names in current directory.
For reading the first line of a file from terminal (on Ubuntu and Mac), check here.
Note: you do not need to install anything, it is built-in on your Ubuntu/Mac OS.
Step 1: open a terminal
Step 2: cd to the directory where your file (e.g., .txt file) is located
Step 3: issue the following command accordingly
$ ls | head -10 # the pipe symbol (i.e., |) puts the output of the ls command as the input of the head command.
if you would like to get more information of the files, use the following instead:
$ ls -l | head -10
similarly,
if you would like to get the bottom 10 files in the current directory, issue the following command:
$ ls | tail -10
or for detailed information of the files, use
$ ls -l | tail -10
You guessed it, if you would like to get the top/bottom 20, just change the -10 to -20:)
simply, enough, right?
