PROGRAM:
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.
