| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> |
| |
| <i>Tail</i> copies the named file to the standard output beginning at |
| a designated place. If no file is named, the standard input is |
| copied. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| Copying begins at position <tt><font size=+1>+</font></tt><i>number</i> measured from the beginning, |
| or <tt><font size=+1>−</font></tt><i>number</i> from the end of the input. <i>Number</i> is counted in lines, |
| 1K blocks or bytes, according to the appended flag <tt><font size=+1>l</font></tt>, <tt><font size=+1>b</font></tt>, or <tt><font size=+1>c</font></tt>. |
| Default is <tt><font size=+1>−10l</font></tt> (ten ell). |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| The further flag <tt><font size=+1>r</font></tt> causes tail to print lines from the end of |
| the file in reverse order; <tt><font size=+1>f</font></tt> (follow) causes <i>tail</i>, after printing |
| to the end, to keep watch and print further data as it appears. |
| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| The second syntax is that promulgated by POSIX, where the <i>numbers</i> |
| rather than the options are signed.<br> |

| |

| |
| Tails relative to the end of the file are treasured up in a buffer, |
| and thus are limited in length. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| According to custom, option <tt><font size=+1>+</font></tt><i>number</i> counts lines from 1, and counts |
| blocks and bytes from 0. |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
