tr -- translate strings (EXTERNAL) [v1.2]
|
|
Written by Jeff Ding
|
|
|
|
syntax: tr <input pathname> [<output pathname>] -s<search string>
|
|
[-r<replace string>] [-f] [-d] [-w<margin>]
|
|
[-c<number>] [-h<number>]
|
|
|
|
ex: tr infile outfile -s^j
|
|
tr infile temp -s^m -r^m^j -fd
|
|
tr infile -s" " -r"" -m60
|
|
|
|
'Tr' looks for every occurrence of the <search string> in the input
|
|
file and replaces it with the <replace string>. The translated data
|
|
is saved to the output file. If the <output pathname> is not specified,
|
|
output goes to the screen. Wildcards are supported.
|
|
|
|
'Tr' works with any file type, but the input file is always treated as
|
|
a raw collection of bytes; no special processing is done for AWP files.
|
|
If you use 'tr' on an AWP file, you are not guaranteed to get a valid
|
|
AWP file as a result (and if the search and replace strings have
|
|
different lengths, you are guaranteed *not* to!).
|
|
|
|
The search and replace strings are specified in text. The text normally
|
|
has the hi-bits off. To turn the hi-bit of a character on, use the hi-bit
|
|
delimiter, default "~", before the character. To specify a control
|
|
character, use the control character delimiter, default "^", before the
|
|
character. To specify both, use both delimiters in succession; any order
|
|
works. Use "^?" to specify the delete key. Use "^>" to specify the
|
|
control character delimiter. Use "^=" to specify the hi-bit delimiter.
|
|
With these options, it is possible to specify any byte from 0 to 255.
|
|
|
|
Here are some examples:
|
|
|
|
"^j^m" - "ctrl-j ctrl-m" (case for control characters is ignored)
|
|
"~A~B~C" - "ABC" with hi-bits on.
|
|
"AbC" - "AbC" with hi-bits off.
|
|
"~^m^~m" - "ctrl-m ctrl-m" with hi-bits on.
|
|
"^>^=" - "^~"
|
|
|
|
Options are as follows:
|
|
|
|
output pathname: translated data is saved to this file. If not
|
|
specified, output goes to the screen. The output
|
|
file type will always be the same as the input file
|
|
type.
|
|
|
|
-s: search string. (REQUIRED) See above for description. This string
|
|
cannot be null. You must search for at least a 1 byte string. The
|
|
string can be at most 63 characters long AFTER control characters
|
|
and hi-bit characters are translated.
|
|
|
|
-r: replace string. See above for description. The string can be at
|
|
most 63 characters long AFTER control characters and hi-bit
|
|
characters are translated. Omitting this option is the same as
|
|
specifying the null string (matches of the search string are
|
|
replaced by nothing, the null string).
|
|
|
|
-f: force overwrite. Skips the "Okay to overwrite" question if the
|
|
output file already exists.
|
|
|
|
-d: delete original. Deletes the original file and renames the
|
|
output file to the original name. The output file is needed
|
|
as a temporary storage. Version 1.1 fixes a bug that caused
|
|
this option not to work.
|
|
|
|
-c <ascii number>: determines what character is used for the
|
|
control delimiter character. Use the ascii value
|
|
for the character.
|
|
|
|
-h <ascii number>: determines what character is used for the
|
|
hi-bit delimiter character. Use the ascii value
|
|
for the character.
|
|
|
|
-w <margin>: wrap margin. Affects output to the screen only. This
|
|
forces a carriage return when either the margin or a
|
|
space within 9 characters of the margin is reached.
|
|
Allowed values are 0 through 255. A 0 value has the same
|
|
effect as not using the option.
|
|
|
|
Version 1.2 fixes a bug when the search string was more than one
|
|
character long.
