Hi gcue, try this

$filename = "testdel.txt"
$text = FileRead($filename)
$replace = "some text"
$text = StringRegExpReplace($text,"\h*\Q" & $replace & "\E.*\cM\cJ","")
$hf = FileOpen($filename,2)
FileWrite($hf,$text)

EDIT:Corrected so does not leave an empty line.

try this:

#Include <File.au3>
Global $success = False
$file_name = FileOpenDialog("Select file", @ScriptDir, "All files (*.*)", 1+4)
$line_text_input = InputBox("Line's text", "Line must contain following text:", "line contains this text")
$file_count_lines = _FileCountLines($file_name)
for $i = 0 to $file_count_lines
    $Lines_text_output = FileReadLine($file_name, $i)
    if StringInStr($Lines_text_output, $line_text_input) then
        _FileWriteToLine($file_name, $i, "", 1)
        $success = True
        ExitLoop
    EndIf
Next
if $success = True Then
    MsgBox(0, "Success", "Line has been deleted")
Else
    MsgBox(0, "Failure", "Line wasn't found")
EndIf

hey martin =)

that works but it still leaves a blank line.

Hi gcue, try this

$filename = "testdel.txt"
$text = FileRead($filename)
$text = StringRegExpReplace($text,"\v\h*\Qsome text\E.*","")
$hf = FileOpen($filename,2)
FileWrite($hf,$text)

sandin that works great.. im trying to repeat it for all instances and predefine the line to replace

heres what i have..

not sure how i can loop it so it will replace all instances

#Include <File.au3>

Global $success = False

$filename = "C:\CRS\Tools\Account_Info\gxm_novell.txt"

$line_text_input = "Subject:"

$file_count_lines = _FileCountLines($filename)

for $i = 0 to $file_count_lines

$Lines_text_output = FileReadLine($filename, $i)

if StringInStr($Lines_text_output, $line_text_input) then

_FileWriteToLine($filename, $i, "", 1)

$success = True

ExitLoop

EndIf

Next

ShellExecute($filename)

try this:

#Include <File.au3>
Global $success = False
$file_name = FileOpenDialog("Select file", @ScriptDir, "All files (*.*)", 1+4)
$line_text_input = InputBox("Line's text", "Line must contain following text:", "line contains this text")
$file_count_lines = _FileCountLines($file_name)
for $i = 0 to $file_count_lines
    $Lines_text_output = FileReadLine($file_name, $i)
    if StringInStr($Lines_text_output, $line_text_input) then
        _FileWriteToLine($file_name, $i, "", 1)
        $success = True
        ExitLoop
    EndIf
Next
if $success = True Then
    MsgBox(0, "Success", "Line has been deleted")
Else
    MsgBox(0, "Failure", "Line wasn't found")
EndIf
