NAME
head - give first few lines SYNOPSIS
count] [file ...] Obsolescent: [file ...] DESCRIPTION
prints on standard output the first count lines of each of the specified files, or of the standard input. If count is omitted it defaults to 10. If multiple files are specified, outputs before each file a line of this form: file Options The quantity of output is measured in bytes. The number of units of output. This option is provided for backward compatibility (see below) and is mutually exclusive of all other options. The quantity of output is measured in lines; this is the default. The number of lines (default) or bytes output. count is an unsigned decimal integer. If (or is not given, the default quantity is 10. This option provides the same func- tionality as the option, but in a more standard way. Use of the option is recommended where portability between systems is important. EXTERNAL INFLUENCES
Environment Variables determines the interpretation of text within file as single and/or multi-byte characters. determines the language in which messages are displayed. If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. WARNINGS
The length of the input lines is limited to bytes. SEE ALSO

NAME
comm - select or reject lines common to two sorted files SYNOPSIS
file1 file2 DESCRIPTION
comm reads file1 and file2, which should be ordered in increasing collating sequence (see sort(1) and Environment Variables below), and produces a three-column output: Column 1: Lines that appear only in file1, Column 2: Lines that appear only in file2, Column 3: Lines that appear in both files. If is used for file1 or file2, the standard input is used. Options 1, 2, or 3 suppress printing of the corresponding column. Thus prints only the lines common to the two files; prints only lines in the first file but not in the second; does nothing useful. EXTERNAL INFLUENCES
Environment Variables determines the collating sequence expects from the input files. determines the language in which messages are displayed. If is not specified in the environment or is set to the empty string, the value of determines the language in which messages are displayed. If is not specified in the environment or is set to the empty string, the value of is used as a default. If is not specified or is set to the empty string, a default of ``C'' (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to ``C''. See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. EXAMPLES
The following examples assume that and have been ordered in the collating sequence defined by the or environment variable. Print all lines common to and (in other words, print column 3): Print all lines that appear in but not in (in other words, print column 1): Print all lines that appear in but not in (in other words, print column 2): SEE ALSO
