11 Translate, squeeze, and/or delete characters from standard input,
12 writing to standard output.
14 \fB\-c\fR, \fB\-C\fR, \fB\-\-complement\fR
17 \fB\-d\fR, \fB\-\-delete\fR
18 delete characters in SET1, do not translate
20 \fB\-s\fR, \fB\-\-squeeze\-repeats\fR
21 replace each input sequence of a repeated character
22 that is listed in SET1 with a single occurrence
25 \fB\-t\fR, \fB\-\-truncate\-set1\fR
26 first truncate SET1 to length of SET2
29 display this help and exit
32 output version information and exit
34 SETs are specified as strings of characters. Most represent themselves.
35 Interpreted sequences are:
38 character with octal value NNN (1 to 3 octal digits)
65 all characters from CHAR1 to CHAR2 in ascending order
68 in SET2, copies of CHAR until length of SET1
71 REPEAT copies of CHAR, REPEAT octal if starting with 0
74 all letters and digits
80 all horizontal whitespace
83 all control characters
89 all printable characters, not including space
92 all lower case letters
95 all printable characters, including space
98 all punctuation characters
101 all horizontal or vertical whitespace
104 all upper case letters
107 all hexadecimal digits
110 all characters which are equivalent to CHAR
112 Translation occurs if \fB\-d\fR is not given and both SET1 and SET2 appear.
113 \fB\-t\fR may be used only when translating. SET2 is extended to length of
114 SET1 by repeating its last character as necessary. Excess characters
115 of SET2 are ignored. Only [:lower:] and [:upper:] are guaranteed to
116 expand in ascending order; used in SET2 while translating, they may
117 only be used in pairs to specify case conversion. \fB\-s\fR uses SET1 if not
118 translating nor deleting; else squeezing uses SET2 and occurs after
119 translation or deletion.
