I have a script that install several programs.

I would like to write a series of batch scripts to log these installs.

I was hoping to find a command that would allow me to select this text file and write a line to the file each time it runs.

  • flash installs
  • batch file runs and logs text "flash installed" to c:\log\logfile.txt
  • java installs
  • batch file runs and writes text "java installed" to c:\log\logfile.txt
  • and so on

so that in log file when finished it has

flash installed
java installed
chrome installed
so on

so forth

However, I'm finding a lot of scripts for writing to specific lines or editing specific strings of text. I'm not seeing any scripting for just write to the next blank line. Perhaps I'm going about this the wrong way.

To append a line to a text file using a windows command line batch script you can use output redirection using the greater-than sign twice >>. For example

echo "java installed" >> c:\log\logfile.txt


  • You can also type 1>> for stdout, 2>> for stderr
