.SH NAME
.B unixize
\- bulk rename directory contents
.
.
.SH SYNOPSIS
.SY unixize
.RB [ \-ahiknprRv ]
[\c
.BI \-e ext\c
]
.I directory
.YS
.
.
.SH DESCRIPTION
.PP
The
.B unixize
utility renames all file in a given
.I directory
to a predefined style. Here is a description of the
.B unixize
behaviour without options. This behavious can be changed using options, see
\(lqOPTIONS\(rq below. By default:
.
.PP
.
All upper-case characters will be set to lower-case.
.
.file_example "FILE" "file"
.
Spaces will be substitued by a
.BR separator ,
by default underscores
.squoted_text _ ). (
.
.file_example "a file with spaces.org" "a_file_with_spaces.org"
.
Multiple spaces will be condensed into only one
.BR separator .
.
.file_example "lots      of     spaces.gif" "lots_of_spaces.gif"
.
By default the
.BR "opposite separator"
is hyphen
.squoted_text - ). (
All
.BR "opposite separator"
will be changed to the chosen
.BR separator ,
underscores
.squoted_text _ ) (
by default.
.
.file_example "2004-with-the-lights-out" "2004_with_the_lights_out"
.
All unicode characters will be deleted
except for latin extended ascii characters, which will be replaced by the most
relevant ascii character (or double characters).
.
.file_example "\(EuHliðskjálf\(de\(dd.jpg" "hlidhskjalf.jpg"
.
Two special patterns are always substitued, regardless of options.
.PP
The first sequence is
.dquoted_text C\+\+ ,
which will always be changed to
.dquoted_text cxx
whether the letter
.squoted_text C
is upper-case or lower-case.
.
.file_example "learn_c++_programming.pdf" "learn_cxx_programming.pdf"
.
The second one is the special case where the filename begins with a number,
followed directly by a dot
.squoted_text . ) (
and another dot
.squoted_text . ) (
can be found later in the filename (for example the file's extension). In this
case, the first dot is removed.
.
.file_example "07. Negative Creep.flac" "07_negative_creep.flac"
.
If another dot
.squoted_text . ) (
can't be found, nothing is changed.
.
.file_example "255.sql" "255.sql"
.
In the case where the renamed version of a file is already present in the
.I directory
(for example if \(lqREADME\(rq is being unixized but another \(lqreadme\(rq
already exists), or if the renamed version is empty of text, the renaming of
this file will be skipped.
.SH OPTIONS
.TP
.B \-a
Include directory entries whose names begin with a dot
.squoted_text . ). (
.TP
.BI \-e\c ext
Unixize certain file extensions.
.I ext
can be either
.IR 0 ,
.I 1
or
.IR 2 .
Some file extensions are often prefered over other ones to specify the same file
type in UNIX-like operating systems. With
.I ext
set to
.IR 1 ,
.dquoted_text .asm
extensions will be changed to
.dquoted_text .S ,
.dquoted_text .cpp
extensions will be changed to
.dquoted_text .cc ,
.dquoted_text .hpp
extensions will be changed to
.dquoted_text .hh
and
.dquoted_text .txt
files will see their extension removed. When
.I ext
is set to
.IR 2 ,
all the previous rules are applied as well except that
.dquoted_text .cpp
extensions will be changed to
.dquoted_text .cxx
and
.dquoted_text .hpp
extensions will be changed to
.dquoted_text .hxx .
Default:
.IR 0 .
q.TP
.B \-h
Output a brief help message.
.TP
.B \-i
Prompt user before running
.B unixize
on the specified directory. If the
.B \-R
option is being used, the user will be prompted for each subdirectory the
program is entering.
.TP
.B \-k
Keep the opposite separator occurences in the filename. If the
.B \-n
option is not being used, all existing hyphens
.squoted_text - ) (
will be preserved. Otherwise, all existing underscores
.squoted_text _ ) (
will be kept.
.RS 12

.RE
.TP
.B \-n
Use hyphens
.squoted_text - ) (
instead of underscores
.squoted_text _ ) (
as a
.B separator
and sets underscores as the
.BR "opposite separator" .

.TP
.B \-p
Pretend only.
.B unixize
will run normally but will not actually rename any file. This
option is intended to be used with the
.B \-v
and/or
.B \-r
options.
.TP
.B \-R
Recursive mode. The program will enter and repeat into every subdirectories.
.TP
.B \-r
Reverse verbose mode. Files that are not being renamed will be displayed to
stdout.
.TP
.B \-v
Verbose mode. File that are being renamed will be displayed to to stdout as well
as their new version.
.
