Cygwin .sh 文件作为 Windows 任务计划程序运行

Question

Having issues getting this shell script to run in windows task scheduler.

#!/bin/bash
# Script to ping the VPN server for testing

RESULT=$(ping 192.168.1.252 | grep "Lost" | awk {' print $10 '})
LOG=/home/admin/results.txt

if [ "$RESULT" -gt 0 ];then

    echo "VPN 192.168.1.252 NOT pinging" >> $LOG
else

echo "VPN Online"

fi

When I run it in cygwin, it runs with no issue, but when I attempt to run it from command prompt, I get the following:

C:\cygwin64\bin>bash test.sh test.sh: line 4: grep: command not found

test.sh: line 4: awk: command not found

test.sh: line 7: [: : integer expression expected

My question is, how do I get it to run with bash instead so that it actually knows the grep and awk commands?

In Windows Scheduler, I have Action: Start A Program Details: C:\cygwin64\bin\bash.exe Argument: test.sh Start in: C:\cygwin64\bin

Am I missing something?

Answer 1

I figured it out.

In the Windows Task Scheduler, I had to pass:

Program/script: C:\cygwin64\bin\bash.exe

Add arguments: -c -l test.sh

Start in: C:\cygwin64\bin

Answer 2

In correction to what Jimmy found:

Add arguments: -c -l "c:/FileFolder/test.sh"

You don't need the Start in argument anymore.

Answer 3

For the longest time I was experiencing the same issue as the OP: command not found errors when trying to run a shell script from Task Scheduler or the Command Prompt, despite the fact that running the same script from a Cygwin terminal worked fine.

After some more research I eventually realised that the reason was because my usual Bash PATH ~/.bashprofile wasn't being loaded, and that I needed to use Windows' Environment Variables window to add C:\cygin64\bin to my PATH environment variable (system or user, it doesn't really matter). This directory contains common system executables like grep and awk , which is why Bash is unable to locate them until the path is added to Windows' PATH.
