Full Discussion: Bash Scripting Help to automate replacing multiple lines
Top Forums Shell Programming and Scripting Bash Scripting Help to automate replacing multiple lines Post 302746001 by joeyg on Tuesday 18th of December 2012 03:17:29 PM

One thing that comes to mind is..
Code:
head -7 myfile.txt

will extract the first 7 lines
Code:
tail -n +18 myfile.txt

will extract beginning at line 18

So, assuming you have your new message in a file called new.txt, you could do something like:
Code:
head -7 myfile.txt >t1.txt
tail -n +18 myfile.txt >t2.txt
cat t1.txt new.txt t2.txt >newfile.txt
