NAME

       tr - translate characters

SYNOPSIS

       tr [ -cds ] [ string1 [ string2 ] ]

DESCRIPTION

       Tr  copies  the standard input to the standard output with substitution or deletion of selected characters (runes).  Input characters found
       in string1 are mapped into the corresponding characters of string2.  When string2 is short it is padded to the length of string1 by  dupli-
       cating its last character.  Any combination of the options -cds may be used:

       -c     Complement string1: replace it with a lexicographically ordered list of all other characters.

       -d     Delete from input all characters in string1.

       -s     Squeeze repeated output characters that occur in string2 to single characters.

       In  either  string a noninitial sequence -x, where x 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 x.  The character followed by 1,  2  or  3  octal
       digits  stands for the character whose 16-bit value is given by those digits.  The character sequence followed by 1, 2, 3, or 4 hexadecimal
       digits stands for the character whose 16-bit value is given by those digits.  A followed by any other character stands for that character.

EXAMPLES

       Replace all upper-case ASCII letters by lower-case.

	      tr A-Z a-z <mixed >lower

       Create a list of all the words in one per line in where a word is taken to be a maximal string of  alphabetics.	 String2  is  given  as  a
       quoted newline.

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

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

NOTES

       Will not handle ASCII NUL in string1 or string2. tr always deletes NUL from input.
