== NAME ==
tr - translate characters

== SYNOPSIS ==
tr [ -cds ] [ string1 [ string2 ] ]

== DESCRIPTION ==
_T_r copies the standard input to the standard output with
substitution or deletion of selected characters. Input
characters found in _s_t_r_i_n_g_1 are mapped into the correspond-
ing characters of _s_t_r_i_n_g_2. When _s_t_r_i_n_g_2 is short it is pad-
ded to the length of _s_t_r_i_n_g_1 by duplicating its last charac-
ter. Any combination of the options -cds may be used: -c
complements the set of characters in _s_t_r_i_n_g_1 with respect to
the universe of characters whose ASCII codes are 01 through
0377 octal; -d deletes all input characters in _s_t_r_i_n_g_1; -s
squeezes all strings of repeated output characters that are
in _s_t_r_i_n_g_2 to single characters.

In either string the notation _a-_b means a range of charac-
ters from _a to _b in increasing ASCII order. The character
`\' followed by 1, 2 or 3 octal digits stands for the char-
acter whose ASCII code is given by those digits. A `\' fol-
lowed by any other character stands for that character.

The following example creates a list of all the words in
`file1' one per line in `file2', where a word is taken to be
a maximal string of alphabetics. The second string is
quoted to protect `\' from the Shell. 012 is the ASCII code
for newline.

tr -cs A-Za-z '\012' <file1 >file2

== BUGS ==
Won't handle ASCII NUL in _s_t_r_i_n_g_1 or _s_t_r_i_n_g_2; always deletes
NUL from input.
