NAME

       tr - translate characters

SYNOPSIS

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

DESCRIPTION

       The tr utility 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 posi-
       tion 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.

EXAMPLES

       Example 1: Creating a list of all the words in a filename

       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.

       example% tr -cs A-Za-z '12' <filename1>filename2
