Is it possible to run head & use nl to number the lines?
Clash Royale CLAN TAG#URR8PPP
When i ran head file.txt && nl file.txt it did each command in order of occurance (which makes sense). Is it possible to have the head display with numbered lines, so that this:
word
word
word
would become this:
1 word
2 word
3 word
head nl

head file.txt | nl
The | creates a pipeline that takes the output of head file.txt and gives it to nl as its "standard" input. Bare nl without a file name will read its standard input and number it, so you get the output of head numbered as you wanted.
Without a pipe providing input, just
nl
would read input from the terminal that you typed. The pipe is a way of providing that data as though you'd typed it in like that.
You can pipe from any command that prints its output, and pipe to any command that reads from the terminal like that, and even pipe several things together:
head -n 50 file.txt | nl | tail -n 20
will give you numbered lines 31-50 from the file.
