regcmp

/usr/ccs/bin/regcmp [- ] files

Stands for "regular expression compile." Compile the regular expressions in one or more files and place output in file .i (or in file .c if - is specified). The output is C source code, while the input entries in files are of the form:

C variable
     "regular expression
"

The purpose of this program is to precompile regular expressions for use with the regex (3C) library routine, avoiding the overhead of the regcmp (3C) function.
