Shell exercises 21 files show content three lines as one line

Requirement: One file displays the content three line as a line

Idea: is the second line of content, the contents of the third row is appended to the first row, so that the contents of three lines can become a row, if not enough three lines automatically melt into a row, as follows

[Email protected] shell]# cat/tmp/chy.txt 1234g68 (view chy.txt content) [[email protected] shell]# vim yihang.sh#!/bin/bash# This was San hang Bian Wei Yi hangsed ' N; n;s/\n//g '/tmp/chy.txt (script content explanation: The meaning of n is to add the next line of content to the new line to change the line number, two n is the content of the two rows into a row,/g is to get N content cache instead of Chy.txt content)

Hope to see the children's shoes a lot of advice, thank you!
