NAMEhead — display first lines of a file
|head||[ -n count | -c bytes][ file ...]|
DESCRIPTIONThis filter displays the first count lines or bytes of each of the specified files, or of the standard input if no files are specified. If count is omitted it defaults to 10.
If more than a single file is specified, each file is preceded by a header consisting of the string “==> XXX <==” where “XXX” is the name of the file.
EXIT STATUSThe head utility exits 0 on success, and >0 if an error occurs.
EXAMPLESTo display the first 500 lines of the file foo:
$ head -n 500 foo
head can be used in conjunction with tail(1) in the following way to, for example, display only line 500 from the file foo:
$ head -n 500 foo | tail -n 1
HISTORYThe head command appeared in PWB UNIX.
