NAME

SYNOPSIS

DESCRIPTION

The output file, if not specified on the command line, is named source_file.dat.

The options are as follows:

-C

Flag the file as containing comments. This option cases the STR_COMMENTS bit in the header str_flags field to be set. Comments are designated by two delimiter characters at the beginning of the line, though strfile does not give any special treatment to comment lines.

-c char

Change the delimiting character from the percent sign to char.

-i

Ignore case when ordering the strings.

-o

Order the strings in alphabetical order. The offset table will be sorted in the alphabetical order of the groups of lines referenced. Any initial non-alphanumeric characters are ignored. This option causes the STR_ORDERED bit in the header str_flags field to be set.

-r

Randomize access to the strings. Entries in the offset table will be randomly ordered. This option causes the STR_RANDOM bit in the header str_flags field to be set.

-s

Run silently; do not give a summary message when finished.

-x

Note that each alphabetic character in the groups of lines is rotated 13 positions in a simple caesar cypher. This option causes the STR_ROTATED bit in the header str_flags field to be set.

The format of the header is:

#define	VERSION	1
uint32_t	str_version;	/* version number */
uint32_t	str_numstr;	/* # of strings in the file */
uint32_t	str_longlen;	/* length of longest string */
uint32_t	str_shortlen;	/* length of shortest string */
#define	STR_RANDOM	0x1	/* randomized pointers */
#define	STR_ORDERED	0x2	/* ordered pointers */
#define	STR_ROTATED	0x4	/* rot-13'd text */
#define	STR_COMMENTS	0x8	/* embedded comments */
uint32_t	str_flags;	/* bit field for flags */
char		str_delim;	/* delimiting character */

All fields are written in network byte order.

The purpose of unstr is to undo the work of strfile. It prints out the strings contained in the file source_file in the order that they are listed in the header file source_file.dat to standard output. It is possible to create sorted versions of input files by using -o when strfile is run and then using unstr to dump them out in the table order.
