NAME

       tr - translate character codes

SYNOPSIS

       tr [-cds] [string1] [string2]

OPTIONS

       -c     Complement the set of characters in string1

       -d     Delete all characters specified in string1

       -s     Squeeze all runs of characters in string1 to one character

EXAMPLES

       tr '[A-Z]' '[a-z]' <x >y
			   # Convert upper case to lower case

       tr -d '0123456789' <f1 >f2
			   # Delete all digits from f1

DESCRIPTION

       Tr  performs simple character translation.  When no flag is specified, each character in string1 is mapped onto the corresponding character
       in string2 .

Name
       tr - translate characters

Syntax
       tr [-cds] [string1[string2]]

Description
       The  command copies the standard input to the standard output with substitution or deletion of selected characters.  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 complements the set of characters in string1 with respect
       to the universe of characters whose ASCII codes are 0 through 0377 octal; -d deletes all input  characters  in  string1;  -s  squeezes  all
       strings of repeated output characters that are in string2 to single characters.

       In  either string the notation a-b means a range of characters from a to b in increasing ASCII order.  The backslash character () followed
       by 1, 2 or 3 octal digits stands for the character whose ASCII code is given by those digits.  A  followed 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 '12' <file1 >file2

Options
       -c   Translates complements:  string1 to those not in string1.

       -d   Deletes all characters in string1 from output.

       -s   Squeezes succession of a character in string1 to one in output.

Restrictions
       `', `0', and `00' are equivalent for NUL character.

       `12' is treated as octal 12 and not a NUL followed by characters 1 and 2.
