SYNOPSIS
sccs istext [options] [file1 .. filen]

-V4 Check with SCCS v4 rules. A file is not pure text if it contains one or more null characters, if a line starts with \001 (^A) or if the file does not end with a newline character.

-V6 Check with SCCS v6 rules. A file is not pure text if it contains one or more null characters.

    sccs istext xec.c

SCCS_NO_HELP
    If set, sccs istext will not automatically call help(1) with the SCCS error code in order to print a more helpful error message. Scripts that depend on the exact error messages of SCCS commands should set the environment variable SCCS_NO_HELP and set LC_ALL=C.
