SQ(1)							      General Commands Manual							     SQ(1)

NAME

       sq, unsq - squeeze or unsqueeze a sorted word list

SYNOPSIS

       sq < infile > outfile

       unsq < infile > outfile

DESCRIPTION

       sq compresses a sorted list of words (a dictionary).  For example:
	      sort -u /usr/share/dict/words | sq | gzip -9 > words.sq.gz
       will compress dict by about a factor of 5.

       unsq uncompress the output of sq.  For example:
	      gunzip < words.sq.gz | unsq | sort -f -o words
       will uncompress a dictionary compressed with sq.

       The squeezing is achieved by eliminating common prefixes, and replacing them with a single character which encodes the number of characters
       shared with the preceding word.	The prefix size is encoded as a single printable character: 0-9 represent 0-9, A-Z represent 10-35, and a-
       z represent 36-61.

BUGS

       sq and unsq can only handle words of up to 256 characters.  The input must be sorted, and duplicates must be suppressed.

NAME

       look - Finds lines in a sorted list

SYNOPSIS

       look [-df] [-tcharacter] string [file]

       The look command prints all lines in a sorted file that begin with string.

OPTIONS

       Uses  dictionary  order; only letters, digits, tabs, and spaces are used in comparisons.  Searches without regard to case; treats uppercase
       and lowercase as equivalent.  Ignores character and characters following it in the search string.  If  you  specify  look  -tC  ABCDE,  the
       string  ABCDE  would  become  (in  effect)  AB, with CDE being ignored.	This option is primarily for shell scripts, in which more than one
       string is being processed.

DESCRIPTION

       If no file is specified, look searches in the system word list /usr/share/dict/words, with the options -df assumed by default.

       The look command uses binary search.

       The -d and -f options affect comparisons as in sort.

NOTES

       In order to use the -f option, you must first sort file with the sort -f command; otherwise, look displays only lowercase items.

       If you do not specify -f, but specify a file (such as /usr/share/dict/words) that has been sorted with sort -f, look may  not  produce  any
       output.

EXAMPLES

       To search a sorted file called sortfile for all lines that begin with the string as, enter: look as sortfile To search the system word list
       for all words beginning with smi, enter: look smi

	      This might result in: smile smirk smith smithereens Smithfield Smithson smithy smitten

FILES
