Command to erase?

[Burgs]

Greetings,

Is there a command available to "erase" the contents of a file? I simply want to write a line or lines to a .txt file and then later erase it so the file is "empty". However I do not wish to delete the .txt file...possible? Thanks in advance.

Look in the help file for FileOpen(). You can specify to open the file in Write Mode. This will erase all previous content.

Something like:

$file = FileOpen("test.txt", 2);2=write mode
FileWrite($file,"");not sure if this is nessesary. Try.
FileClose($file)

#include <file.au3>
$file = "filename.txt"
$CountLines = _FileCountLines($file)
For $x = 1 To $CountLines
    _FileWriteToLine($file, $x, "", 1)

something basic like this should get you off to a good start I hope, look theses functions up in the helpfile and you'll really get the hang of it hopefully.

Global $Text[3]

$Text[1] = "Hello"
$Text[2] = "I hope this is what your looking for..."

$Path = @ScriptDir & "\test.txt"

FileWrite($Path , "")
FileOpen($Path , 2)
FileWrite($Path , $Text[1] & @CRLF & $Text[2])
FileClose($Path)

Hello. I have a similar problem, and the suggestions above don't work for me, because that line is still there and it is blank. It makes the line blank, but I need it to erase the line completely and bring up the info below. Eg.

James

Smith

401 Adams Ave.

Montgomery

36104

Harry

Brown

402 Adams Ave.

Montgomery

36104

My bot reads the first 5 lines. I want it to erase the first 5 lines after it is done reading them to bring up the info below it to where it was before. Eg. After the erase the file will look like this:

Harry

Brown

402 Adams Ave.

Montgomery

36104

This way the bot can loop again and read the first 5 lines again, etc.

Thanks!
