Change case 1

[Ambatim]

In vi, how can I change the case(from uppercase to lower or vice-versa), of all characters
in particular lines, say from line 10 to line 100 ??

If not possible in vi can I do it outside of vi using any commmand ???

Thanks in advance

awk '{if (NR>=10 && NR<=100) print toupper($0); else print $0 }' < file1 > file2

:2,200!tr &quot;[a-z]&quot; &quot;[A-Z&quot;

To convert a range to all uppercase or lowercase, use

10,100s/.*/\U&/

or

10,100s/.*/\L&/
