NAME
trbsd - Translates characters SYNOPSIS
trbsd [-Acs] string1 string2 trbsd -d [-Ac] string1 The trbsd command copies characters from the standard input to the standard output with substitution or deletion of selected characters. OPTIONS
Translates on a byte-by-byte basis. When you specify this option, trbsd does not support extended characters. Complements (inverts) the set of characters in string1 with respect to the universe of characters whose codes are 001 through 377 octal if you specify -A, and all characters if you do not specify -A. Deletes all characters in string1 from output. Changes characters that are repeated output charac- ters in string2 into single characters. DESCRIPTION
Input characters from string1 are replaced with the corresponding characters in string2. The trbsd command cannot handle an ASCII NUL (00) in string1 or string2; it always deletes NUL from the input. The tr command is a System V compatible version of trbsd. Abbreviations such as a-z, standing for a string of characters whose ASCII codes run from character a to character z, inclusive, can be used to introduce ranges of characters. Note that brackets are not special characters. Use the escape character (backslash) to remove the special meaning from any character in a string. Use the followed by 1, 2, or 3 octal digits for the code of a character. If a given character appears more than once in string1, the character in string2 corresponding to its last appearance in string1 will be used in the translation. EXAMPLES
To translate braces into parentheses, enter: trbsd '{}' '()' <textfile >newfile This translates each { (left brace) to a ( (left parenthesis) and each } (right brace) to a ) (right parenthesis). All other char- acters remain unchanged. To translate lowercase ASCII characters to uppercase, enter: trbsd a-z A-Z <textfile >newfile The two strings can be of different lengths: trbsd 0-9 # <textfile >newfile This translates each digit to a # (number sign); if string2 is too short, it is padded to the length of string1 by duplicating its last character. To translate each string of digits to a single # (number sign), enter: trbsd -s 0-9 # <textfile >newfile To trans- late all ASCII characters that are not specified, enter: trbsd -c ' -~' 'A-_' <textfile >newfile This translates each nonprinting ASCII character to the corresponding control key letter (01 translates to A, 02 to B, and so on). ASCII DEL (177), the character that follows ~ (tilde), translates to a ? (question mark). SEE ALSO

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 ATTRIBUTES
