The ``tags'' feature of Emacs includes the command
@code{tags-query-replace} which performs a query-replace across all the
files mentioned in the @file{TAGS} file. @inforef{Tags Search, Tags Search,
emacs}.
As of Emacs 19.29, Dired mode (@kbd{M-x dired @key{RET}}, or @kbd{C-x
d}) supports the command @code{dired-do-query-replace} (@kbd{Q}), which
allows users to replace regular expressions in multiple files.
As of Emacs 19.29, Dired mode (@kbd{M-x dired @key{RET}}, or @kbd{C-x d})
supports the command @code{dired-do-query-replace} (@kbd{Q}), which allows
users to replace regular expressions in multiple files.
You can use this command to perform search/replace operations on
multiple files by following the following steps:
@itemize @bullet
@item
Assemble a list of files you want to operate on with either
@code{find-dired}, @code{find-name-dired} or @code{find-grep-dired}.
@item
Mark all files in the resulting Dired buffer using @kbd{t}.
@item
Use @kbd{Q} to start a @code{query-replace-regexp} session on the marked
files.
@item
To accept all replacements in each file, hit @kbd{!}.
@end itemize
Another way to do the same thing is to use the ``tags'' feature of
Emacs: it includes the command @code{tags-query-replace} which performs
a query-replace across all the files mentioned in the @file{TAGS} file.
