{{mirc title|/bwrite Command}}
+
The '''/bwrite command''' can be used to write a specified amount of bytes from the string/buffer to a given file starting at the start_pos position.
−
The '''/bwrite''' command can be used to write a specified amount of bytes from the string/buffer to a given file starting at the start_pos position.
 
−
 
 
−
'''Note''': the starting position is 0, not 1.

  /bwrite -act <filename> <start_pos> <length> <text|%var|&binvar>
+
  /bwrite <filename> <start_pos> [length] <text|%var|&binvar>

/bwrite -t <filename> <start_pos> [length] <text|%var>

−
'''Note''': If you pass a %var to /bwrite, if the content of that %var is a %variable itself, of if the first token of %var is a %variable itself, the content of %variable is used and no tokenization on %variable occurs, effectively preserving spaces. See the example
 
  
 
== Switches ==
 
== Switches ==
−
* '''-t''' - Treats everything as plain text (i.e. $identifiers and %variables (but not contents of %variables) are evaluated, but binary variables are not evaluated, are treated as text strings beginning with &) This switch is needed if literal string begins with &  or string within %var begins with & or % characters.
+
* '''-t''' - Treats everything as plain text (i.e. binary variables are not evaluated)
−
* '''-c''' - Chops the file at the end of the written data (if your current disk file is 10 bytes and you write 3 bytes at position 3 (4th byte), the resulting disk file's filesize is 6 because the 3 bytes were written as the 4th through 6th bytes of the file)
 
−
* '''-a''' - Disables UTF-8 encoding of characters in the range 0-255, as long as the line contains no characters > 255
 
  
 
== Parameters ==
 
== Parameters ==
 
* '''<filename>''' - the file name to be modified
 
* '''<filename>''' - the file name to be modified
−
* '''<start_pos>''' - the position in the file to start writing at. First byte of the file is 0. Using -1 appends data to the end of existing file.
+
* '''<start_pos>''' - the position in the file to start writing at
−
* '''[length]''' - Length of the data to be written. Using -1 writes entire length of source text or variable.
+
* '''[length]''' - Length of the data to be written
 
* '''<text|%var|&binvar>''' - data to be written to the file
 
* '''<text|%var|&binvar>''' - data to be written to the file

displays "a  b"

because the first token in %a is a variable (%b). Adding the -t switch  would have instead written the literal string "%b".
