Editing Diff (section)

=== Edit script ===
An [[Ed (text editor)|ed script]] can still be generated by modern versions of diff with the <code>-e</code> option. The resulting edit script for this example is as follows:

 24'''a'''
 
 ''This paragraph contains''
 ''important new additions''
 ''to this document.''
 .
 17'''c'''
 ''check this document. On''
 .
 11,15'''d'''
 0'''a'''
 ''This is an important''
 ''notice! It should''
 ''therefore be located at''
 ''the beginning of this''
 ''document!''
 
 .

In order to transform the content of file ''original'' into the content of file ''new'' using {{Mono|ed}}, we should append two lines to this diff file, one line containing a <code>w</code> (write) command, and one containing a <code>q</code> (quit) command (e.g. by {{code|lang=bash|printf "w\nq\n" >> mydiff}}). Here we gave the diff file the name ''mydiff'' and the transformation will then happen when we run {{code|lang=bash|ed -s original < mydiff}}.
