head is a program on Unix and Unix-like systems used to display the beginning of a text file or piped data. The command syntax is: head () <file_name> By default, head will print the first 10 lines of its input to the standard output. The number of lines printed may be changed with a command line option. The following example shows the first 20 lines of ''filename'': head -n 20 ''filename'' This displays the first 5 lines of all files starting with ''foo'': head -n 5 ''foo *'' Most versions allow omitting the n and just let you say -5. GNU head allows negative arguments for -n option, meaning to print all but the last - argument value counted - lines of each input file. ==Flags== -c 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Head (Unix)」の詳細全文を読む スポンサード リンク
