captoinfo(1m)                    User commands                   captoinfo(1m)




NAME

       captoinfo - convert a termcap description into a terminfo description


SYNOPSIS

       captoinfo [tic-option] [file ...]

       captoinfo -V


DESCRIPTION

       captoinfo  translates  terminal  descriptions.   It looks in each given
       text file for termcap entries  and,  for  each  one  found,  writes  an
       equivalent terminfo description to the standard output stream.  termcap
       tc capabilities translate to terminfo "use" capabilities.

       If no files are specified, captoinfo  interprets  the  content  of  the
       environment  variable  TERMCAP  as  a  file name, and extracts only the
       entry for the terminal named in the environment variable TERM from  it.
       If  the  environment  variable  TERMCAP  is  not  set,  captoinfo reads
       /etc/termcap.

       This utility is implemented as a link to tic(1m), with the latter's  -I
       option  implied.  You can use other tic options such as -1, -f, -v, -w,
       and -x.  The -V option reports the version of ncurses  associated  with
       this program and exits with a successful status.


Translations from Nonstandard Capabilities

       captoinfo  translates  some  obsolete,  nonstandard  capabilities  into
       standard  (SVr4/XSI  Curses)  terminfo  capabilities.   It   issues   a
       diagnostic  to the standard error stream for each, inviting the user to
       check that it has not mistakenly  translated  an  unknown  or  mistyped
       capability name.

       XENIX termcap had a set of extension capabilities, corresponding to box
       drawing characters of CCSID ("code page") 437, as follows.

       captoinfo composes single-line capabilities into an  acsc  string,  and
       discards GG and double-line capabilities with a warning diagnostic.

       IBM's  AIX  has  a  terminfo facility descended from SVr1 terminfo, but
       which is incompatible with the SVr4 format.  captoinfo  translates  the
       following AIX extensions.

                                     IBM    XSI
                                    -------------
                                    ksel    kslt
                                    kbtab   kcbt
                                    font0   s0ds
                                    font1   s1ds
                                    font2   s2ds
                                    font3   s3ds

       Additionally,  this  program  translates  the AIX box1 capability to an
       acsc string.

       The  HP-UX  terminfo  library   supports   two   nonstandard   terminfo
       capabilities,  meml  (memory lock) and memu (memory unlock).  captoinfo
       discards these with a warning message.


FILES

PORTABILITY

       X/Open Curses, Issue 7 (2009) describes tic  briefly,  but  omits  this
       program.

       SVr4 systems provide captoinfo as a separate application from tic.  Its
       -v option does not accept a trace level argument n; repeat -v  n  times
       instead.

       NetBSD does not provide this application.
