Writing to 2nd last line of file

Hello,

I'm trying to append a string to the 2nd last line of a text file, but I'm not sure how I can do that. Would this be possible with the NSIS functions or is a plugin needed?

Thanks 😁

See the NSIS documentation,

Name "My Application"

OutFile 'test.exe'

!define TEST_FILE "$EXEDIR\license.txt"



!include TextFunc.nsh



!insertmacro LineFind





Section

        CopyFiles "${NSISDIR}\license.txt" "${TEST_FILE}"



	${LineFind} "${TEST_FILE}" "" "-2" Example4

	IfErrors 0 +2

	MessageBox MB_OK "Error"

	ExecShell open "${TEST_FILE}"

SectionEnd



Function Example4

	FileWrite $R4 "---First Line---$\r$\n"

	FileWrite $R4 "---Second Line ...---$\r$\n"



	Push $0

FunctionEnd
