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
15
use the complement of SET1
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.
