head
head(1) User Commands head(1)NAME
head - display first few lines of files
SYNOPSIS
/usr/bin/head
/usr/bin/head [-number | -n number] [filename]...
ksh93
head [-qv] [-n lines] [-c chars] [-s skip][filename]...
DESCRIPTION
/usr/bin/head
The head utility copies the first number of lines of each filename to the standard output. If no filename is given, head copies lines from
the standard input. The default value of number is 10 lines.
When more than one file is specified, the start of each file looks like:
==> filename <==
Thus, a common way to display a set of short files, identifying each one, is:
example% head -9999 filename1 filename2 ...
ksh93
The head built-in in ksh93 is associated with the /bin and /usr/bin paths. It is invoked when head is executed without a pathname prefix
and the pathname search finds a /bin/head or /usr/bin/head executable.
head copies one or more input files to standard output, stopping at a designated point for each file or to the end of the file whichever
comes first. Copying ends at the point indicated by the options. By default, a header of the form ==> filename <== is output before all but
the first file but this can be changed with the -q and -v options. If no file is given, or if the file is -, head copies from standard
input starting at the current location.
The option argument for -c and -s can optionally be followed by one of the following characters to specify a different unit other than a
single byte:
b 512 bytes
k 1-kilobyte
m 1-megabyte
For backwards compatibility, -number is equivalent to -n number.
OPTIONS
/usr/bin/head
The following options are supported by /usr/bin/head:
-n number The first number lines of each input file is copied to standard output. The number option-argument must be a positive decimal
integer.
-number The number argument is a positive decimal integer with the same effect as the -n number option.
If no options are specified, head acts as if -n 10 had been specified.
ksh93
The following options are supported by the head built-in command in ksh93:
-n Copy lines from each file. The default value is 10.
--lines=lines
-c Copy chars bytes from each file.
--bytes=chars
-q Never output filename headers.
--quiet|silent
-s Skip skip characters or lines from each file before copying.
--skip=skip
-v Always output filename headers.
--verbose
OPERANDS
The following operand is supported:
filename A path name of an input file. If no file operands are specified, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of head when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
EXAMPLES
Example 1 Writing the First Ten Lines of All Files
The following example writes the first ten lines of all files, except those with a leading period, in the directory:
example% head *
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of head: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
