FILE2C(1)						    BSD General Commands Manual 						 FILE2C(1)

NAME

     file2c -- convert file to c-source

SYNOPSIS

     file2c [-sx] [-n count] [prefix [suffix]]

DESCRIPTION

     The file2c utility reads a file from stdin and writes it to stdout, converting each byte to its decimal or hexadecimal representation on the
     fly.  The byte values are separated by a comma.  This also means that the last byte value is not followed by a comma.  By default the byte
     values are printed in decimal, but when the -x option is given, the values will be printed in hexadecimal.  When -s option is given, each
     line is printed with a leading tab and each comma is followed by a space except for the last one on the line.

     If more than 70 characters are printed on the same line, that line is ended and the output continues on the next line.  With the -n option
     this can be made to happen after the specified number of byte values have been printed.  The length of the line will not be considered any-
     more.  To have all the byte values printed on the same line, give the -n option a negative number.

     A prefix and suffix strings can be printed before and after the byte values (resp.)  If a suffix is to be printed, a prefix must also be
     specified.  The first non-option word is the prefix, which may optionally be followed by a word that is to be used as the suffix.

     This program is typically used to embed binary files into C source files.	The prefix is used to define an array type and the suffix is used
     to end the C statement.  The -n, -s and -x options are useful when the binary data represents a bitmap and the output needs to remain read-
     able and/or editable.  Fonts, for example, are a good example of this.

EXAMPLES

     The command:

	   date | file2c 'const char date[] = {' ',0};'

     will produce:

	   const char date[] = {
	   83,97,116,32,74,97,110,32,50,56,32,49,54,58,50,56,58,48,53,
	   32,80,83,84,32,49,57,57,53,10
	   ,0};
