       -i[SUFFIX], --in-place[=SUFFIX]              edit files in place (makes backup if SUFFIX supplied)

     -I extension             Edit files in-place, saving backups with the specified extension.             If a zero-length extension is given, no backup will be saved.  It             is not recommended to give a zero-length extension when in-place             editing files, as you risk corruption or partial content in situ-             ations where disk space is exhausted, etc.             Note that in-place editing with -I still takes place in a single             continuous line address space covering all files, although each             file preserves its individuality instead of forming one output             stream.  The line counter is never reset between files, address             ranges can span file boundaries, and the ``$'' address matches             only the last line of the last file.  (See Sed Addresses.)  That             can lead to unexpected results in many cases of in-place editing,             where using -i is desired.     -i extension             Edit files in-place similarly to -I, but treat each file indepen-             dently from other files.  In particular, line numbers in each             file start at 1, the ``$'' address matches the last line of the             current file, and address ranges are limited to the current file.             (See Sed Addresses.)  The net result is as though each file were             edited by a separate sed instance.
