tr(1BSD)             (BSD System Compatibility)             tr(1BSD)


       NAME
             tr - (BSD) translate characters

       SYNOPSIS
             /usr/ucb/tr [-cds] [string1 [string2] ]

       DESCRIPTION
             tr copies the standard input to the standard output with
             substitution or deletion of selected characters.  The
             arguments string1 and string2 are considered sets of
             characters.  Any input character found in string1 is mapped
             into the character in the corresponding position within
             string2.  When string2 is short, it is padded to the length of
             string1 by duplicating its last character.

             In either string the notation a-b denotes a range of
             characters from a to b in increasing ASCII order.  The
             character \, followed by 1, 2 or 3 octal digits stands for the
             character whose ASCII code is given by those digits.  As with
             the shell, the escape character \, followed by any other
             character, escapes any special meaning for that character.

       OPTIONS
             Any combination of the options -c, -d, or -s may be used:

             -c    Complement the set of characters in string1 with respect
                   to the universe of characters whose ASCII codes are 01
                   through 0377 octal.

             -d    Delete all input characters in string1.

             -s    Squeeze all strings of repeated output characters that
                   are in string2 to single characters.

       EXAMPLE
             The following example creates a list of all the words in
             filename1 one per line in filename2, 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' <filename1>filename2
