I want to create a batch while which finds specific lines in a batch file and are able to edit these lines.
Example:
//TXT FILE//
ex1
ex2
ex3
ex4
i want to let the batch file find 'ex3' and edit this to 'ex5' to let it look like this:
ex1
ex2
ex5
ex4
This question is related to

lines
@echo off
set "replace=something"
set "replaced=different"
set "source=Source.txt"
set "target=Target.txt"
setlocal enableDelayedExpansion
(
for /F "tokens=1* delims=:" %%a in ('findstr /N "^" %source%') do (
set "line=%%b"
if defined line set "line=!line:%replace%=%replaced%!"
echo(!line!
)
) > %target%
endlocal
Source. Hoping it will help some one.
If you are on Windows, you can use FART (Find And Replace Text). It is only 1 single *.exe file (no library needed).
All you need to is run:
fart.exe your_batch_file.bat ex3 ex5
You can do like this:
rename %CURR_DIR%\ftp\mywish1.txt text.txt
for /f %%a in (%CURR_DIR%\ftp\text.txt) do (
if "%%a" EQU "ex3" (
echo ex5 >> %CURR_DIR%\ftp\mywish1.txt
) else (
echo %%a >> %CURR_DIR%\ftp\mywish1.txt
)
)
del %CURR_DIR%\ftp\text.txt
There is no search and replace function or stream editing at the command line in XP or 2k3 (dont know about vista or beyond). So, you'll need to use a script like the one Ghostdog posted, or a search and replace capable tool like sed.
There is more than one way to do it, as this script shows:
@echo off
SETLOCAL=ENABLEDELAYEDEXPANSION
rename text.file text.tmp
for /f %%a in (text.tmp) do (
set foo=%%a
if !foo!==ex3 set foo=ex5
echo !foo! >> text.file)
del text.tmp
ghostdog74's example provided the core of what I needed, since I've never written any vbs before and needed to do that. It's not perfect, but I fleshed out the example into a full script in case anyone finds it useful.
'ReplaceText.vbs
Option Explicit
Const ForAppending = 8
Const TristateFalse = 0 ' the value for ASCII
Const Overwrite = True
Const WindowsFolder = 0
Const SystemFolder = 1
Const TemporaryFolder = 2
Dim FileSystem
Dim Filename, OldText, NewText
Dim OriginalFile, TempFile, Line
Dim TempFilename
If WScript.Arguments.Count = 3 Then
Filename = WScript.Arguments.Item(0)
OldText = WScript.Arguments.Item(1)
NewText = WScript.Arguments.Item(2)
Else
Wscript.Echo "Usage: ReplaceText.vbs <Filename> <OldText> <NewText>"
Wscript.Quit
End If
Set FileSystem = CreateObject("Scripting.FileSystemObject")
Dim tempFolder: tempFolder = FileSystem.GetSpecialFolder(TemporaryFolder)
TempFilename = FileSystem.GetTempName
If FileSystem.FileExists(TempFilename) Then
FileSystem.DeleteFile TempFilename
End If
Set TempFile = FileSystem.CreateTextFile(TempFilename, Overwrite, TristateFalse)
Set OriginalFile = FileSystem.OpenTextFile(Filename)
Do Until OriginalFile.AtEndOfStream
Line = OriginalFile.ReadLine
If InStr(Line, OldText) > 0 Then
Line = Replace(Line, OldText, NewText)
End If
TempFile.WriteLine(Line)
Loop
OriginalFile.Close
TempFile.Close
FileSystem.DeleteFile Filename
FileSystem.MoveFile TempFilename, Filename
Wscript.Quit
You can always use "FAR" = "Find and Replace". It's written under java, so it works where Java works (pretty much everywhere). Works with directories and subdirectories, searches and replaces within files, also can renames them. Also can rename bulk files.Licence = free, for both individuals or comapnies. Very fast and maintained by the developer. Find it here: http://findandreplace.sourceforge.net/
Also you can use GrepWin. Works pretty much the same. You can find it here: http://tools.tortoisesvn.net/grepWin.html
This is the kind of stuff sed
was made for (of course, you need sed on your system for that).
sed 's/ex3/ex5/g' input.txt > output.txt
You will either need a Unix system or a Windows Cygwin kind of platform for this.
There is also GnuWin32 for sed. (GnuWin32 installation and usage).
