TR ST-UNIX User's Manual TR
COMMAND
tr - character translator.
FORMAT
tr [ -cds ] [ string1 [ string2 ] ]
DESCRIPTION
_✓T_✓r copies the standard input to the standard output substi-
tuting or deleting selected characters. Characters found in
_✓s_✓t_✓r_✓i_✓n_✓g_✓1 are mapped into the corresponding characters of
_✓s_✓t_✓r_✓i_✓n_✓g_✓2, with _✓s_✓t_✓r_✓i_✓n_✓g_✓2 being padded with its last character
to the same length as _✓s_✓t_✓r_✓i_✓n_✓g_✓1 if it is shorter.
The -c option causes the complement of _✓s_✓t_✓r_✓i_✓n_✓g_✓1 in characters
whose ASCII codes are 1 through 256 decimal. -d deletes all
input characters in _✓s_✓t_✓r_✓i_✓n_✓g_✓1; -s squeezes all repeated output
characters in _✓s_✓t_✓r_✓i_✓n_✓g_✓2 to single characters.
In either string the notation _✓a-_✓b means a range of charac-
ters from _✓a to _✓b in increasing ASCII order. The character
`\' followed by 1, 2 or 3 octal digits stands for the char-
acter whose ASCII code is given by those digits. A `\' fol-
lowed 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 string of alphabetic characters.
tr -cs A-Za-z '\012' <file1 >file2
