Hello:
I searched here for "vi -c" but found no hits.

Refer to the standards(5) reference page for more information about industry standards and associated tags.
OPTIONS
The default count is 10. [Tru64 UNIX] Specifies the number of bytes to display. If the last byte written is not a newline character, a
newline character is appended to the output. Specifies the number of lines to display Works exactly as -n lines. Obsolescent.
OPERANDS
Path name of the input file. If you do not specify a file, head reads standard input.
DESCRIPTION

EXIT STATUS
The following exit values are returned: Successful completion. An error occurred.
EXAMPLES

name beginning with a period), enter: head *
ENVIRONMENT VARIABLES
The following environment variables affect the execution of head: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari-
ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value,
overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as opposed to multibyte characters in arguments and input files). Determines the
locale for the format and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the
processing of LC_MESSAGES.
