Writes text to specific line in file and overwrite file data

[newuser]

Is it possible to implement these 2 functions below?

1) Writes text to a specific line in a file.

C:\text.txt contain
hello1
hello2
hello3
hello4
hello5

Eg, write>Bye,3,C:\text.txt
Write Bye to c:\text.txt line number 3.
Then result

C:\text.txt now contain
hello1
hello2
Bye
hello4
hello5


2) Overwrite file with new text.

C:\text.txt contain
hello1
hello2
Bye
hello4
hello5

Eg, writefile>yeah,C:\text.txt
Overwrite c:\text.txt with text yeah.
Then result

C:\text.txt now contain
yeah

Yes it's possible.

Add text to specified line

Code: Select all

ReadFile>C:\text.txt,vAllText
//Read text at line 3
ReadLn>C:\text.txt,3,vTextAtLine
//Add text to line 3
StringReplace>%vAllText%,%vTextAtLine%,Bye%CRLF%%vTextAtLine%,vModifiedText
DeleteFile>C:\text.txt
WriteLn>C:\text.txt,r,vModifiedText

Overwrite File

Code: Select all

DeleteFile>C:\text.txt
WriteLn>C:\text.txt,r,yeah

Thanks Rain, but I wanted it in commands like ReadFile, ReadLn, etc,
because I'm doing it in virtual mode(modifying those files in memory).
The CopyFile, WriteLn etc works in virtual mode because its native commands in MS.

I'm not sure I follow. My example has ReadFile, ReadLn, WriteLn etc.

In virtual mode, cant create new files or delete existing files, but can modify existing files.

Thats why I need native ms commands to do it. Since ms native commands using something like/similar called api I think(not sure what you call it, Im not that familliar with those terms).

Eg. I have 2 files named file1.txt and file2.txt in virtual mode.
I can use CopyFile>file1.txt,file2.txt function, it will copy file1.txt contents and overwrite into file2.txt contents in virtual mode.

But I cant use dos xcopy or copy commands to do it, because these commands need physical files(reside on hard disk), it cant work in virtual mode.
