I am not a windows guy and I need to convert the following script to windows batch.

case "$1" in
    touch $LOCKFILE;;

    exit 0;
    if [ -a $LOCKFILE ]
        exit 110
        exit 100
    fi ;;
    echo "Usage: $0 {start|stop|monitor} lock_file

What you posted just looks like an init script for two other scripts.

What does and do?

I would recommend not even looking at batch files and going right for a powershell or vbs script.

A rough untested conversion might be:
switch ($args[0]) {
    "start" {
        set-content -Path ($LOCKFILE) -Value ($null)
    "stop" {
        Remove-Item $LOCKFILE   
    "monitor" {
        if (Test-Path $LOCKFILE ) {
            exit 110
        else {
            exit 100
    default {
        "Usage: $0 {start|stop|monitor} lock_file
        exit 1

Open in new window

What context does the script run?  It looks as slightwv says as being an init script.

The -f just checks if a file exists and takes appropriate action.  In the case of the code you posted, it exits with a different return value.

To check if a file exists in a BAT file, it is almost as simple.

An example of this can be found on Microsoft's site at:

None of this will really help unless you answer the question I asked in the first post:
What does and do?

These seem to be the important pieces to the script you posted.
