It will read a file on stdin and write it as decimal integers on stdout,
this is useful for embedding files in c-sources.
There are a few places where this is needed, and this is a better way than
the current practice of hand-editing the sources.
The command:
date | file2c 'const char date[] = {' ',0};'
will produce:
const char date[] = {
83,97,116,32,74,97,110,32,50,56,32,49,54,58,52,55,58,51,51,32,80,83,84,
32,49,57,57,53,10
,0};
The manual page is 2 lines longer than the source :-)

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm file2c
|
|
utility reads a file from stdin and writes it to stdout, converting each
|
|
byte to its decimal representation on the fly.
|
|
.Pp
|
|
If the first
|
|
.Op string
|
|
is present, it is printed before the data, if the second
|
|
.Op string
|
|
is present, it is printed after the data.
|
|
.Pp
|
|
This program is used to embedd binary or other files into C source files,
|
|
for instance as a char[].
|
|
.Sh EXAMPLE
|
|
The command:
|
|
.Bd -literal -offset indent
|
|
date | file2c 'const char date[] = {' ',0};'
