From a file read 3 to 4 lines, inserted into another file after the line 5 of the sed command line only, not write a shell script, no logic programming language, such as a command line can solve best,
Just learning the sed, thought of this problem, but do not to come out, thank you.

Because of two file operations, so can only think of using two sed.
Sed -n '3, 4 w temp_file file1 & amp; & Sed -i '5 r temp_file file2

CodePudding user response:

Sed - n '3, 4 p' 111. TXT | xargs 1 - I - n {} sed -i '5 s/^/{} \ n/' 222. TXT

Separated with a space by default, if 3, 4 line with no Spaces, can use this
