<p><font size=+1><b>SYNOPSIS </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<tt><font size=+1>tr</font></tt> [ <tt><font size=+1>−cds</font></tt> ] [ <i>string1</i> [ <i>string2</i> ] ]<br>
</table>
<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<i>Tr</i> copies the standard input to the standard output with substitution
or deletion of selected characters (runes). Input characters found
in <i>string1</i> are mapped into the corresponding characters of <i>string2</i>.
When <i>string2</i> is short it is padded to the length of <i>string1</i> by
duplicating its last character. Any combination of the
options <tt><font size=+1>−cds</font></tt> may be used:<br>
<tt><font size=+1>−c</font></tt> Complement <i>string1</i>: replace it with a lexicographically ordered
list of all other characters.<br>
<tt><font size=+1>−d</font></tt> Delete from input all characters in <i>string1</i>.<br>
<tt><font size=+1>−s</font></tt> Squeeze repeated output characters that occur in <i>string2</i> to
single characters.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
In either string a noninitial sequence <tt><font size=+1>−</font></tt><i>x</i>, where <i>x</i> is any character
(possibly quoted), stands for a range of characters: a possibly
empty sequence of codes running from the successor of the previous
code up through the code for <i>x</i>. The character <tt><font size=+1>\</font></tt> followed by 1,
2 or 3 octal digits stands for the character whose 16-bit
value is given by those digits. The character sequence <tt><font size=+1>\x</font></tt> followed
by 1, 2, 3, or 4 hexadecimal digits stands for the character whose
16-bit value is given by those digits. A <tt><font size=+1>\</font></tt> followed by any other
character stands for that character.<br>

Create a list of all the words in <tt><font size=+1>file1</font></tt> one per line in <tt><font size=+1>file2</font></tt>,
where a word is taken to be a maximal string of alphabetics. <i>String2</i>
is given as a quoted newline.<br>
