使用 Vim 替换 in.so 文件中的文本

Question

My need is to replace all cases of a certain text in a.so file.

I use vim to open the file and then use :%!xxd to convert it to a readable format, like in sample output below:

000001a0: f217 4dce 4321 4118 3940 1326 9a3a 62f6  ..M.C!A.9@.&.:b.                                                                                                         
000001b0: 2fde ecdd 0000 0000 0300 0000 a800 0000  /...............                                                                                                         
000001c0: 0100 0000 0600 0000 88c2 2001 0007 4109  .......... ...A.                                                                                                         
000001d0: a800 0000 ac00 0000 ae00 0000 4245 d5ec  ............BE..                                                                                                         
000001e0: bae3 927c 7092 55aa 694a b111 d871 581c  ...|p.U.iJ...qX.                                                                                                         
000001f0: b98d f10e ebd3 ef0e 0000 0000 0000 0000  ................    

My problem is that with this structure, I cannot search over line breaks, making my mission to replace text inachievable by going over search/replace results.

Is there a way to make vim show only the hex values, and without line breaks?

Any other solution that will allow text replacement over line breaks (so it could be done in one shot), is welcome as well.

Thank you!

You can use sed multi-line search in combination with hex escape notation to search and replace any hex patter in any file.
