Cygwin – How to Run a Command at a Certain Time

cygwin;scheduling

I am writing a bash (.sh) script for cygwin. I want to run a certain command at specific time.

I tried the following:

echo "test" | at 19:00

but I get the following error:

The AT command has been deprecated. Please use schtasks.exe instead.

So can I only use Scheduled Task in Windows for this?

Best Answer

The at command from Unix is not available on Cygwin. Cygwin has traditionally used the at command from windows, but this has been deprecated in favour of schtasks.exe.

So the answer to your question is yes: you can only use Scheduled Task in Windows for running a task once.

(You can use cron and set it on a specific date at a specific time... but it will repeat every year unless you remove the task from the crontab.) ;-)

Cygwin has no watch command

There is watch in cygwin. But it isn't installed by default. You need to install procps-ng package to appear watch. (you can run cygwin installer again and it allows to install only the missed packages without reinstalling the whole cygwin)

Instead of watch you can use simple cycle like:

while true ; do check file ; sleep 2 ; done

where check is your command of choice.

I’m not getting syntax coloring in vim (using Cygwin)

You have to set vim in the non compatible mode, so it doesn't behave like vi. You should switch syntax on and switch on filetype detection and plugin detection. Here is a minimal .vimrc you can try:

set nocp
syntax on
filetype plugin indent on

This will make vim behave somewhat nicer and give syntax coloring. But there are a lot more things you could change.

You should install something like pathogen or vundle, so you can easily install new syntax files and other scripts.
