TR(1)							      General Commands Manual							     TR(1)

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
