Can you please have a look on this small script?[SOLVED]

Hello guys,

I am writing a small script which has to do the following:

1. It should run without any interruption. (Therefore while [ 1 ])
2. While working continuously, it should check whether a folder named "check" is available in the folder "/home/arch".
3. If it is the case, it should execute the script /home/arch/shutdownServer1

The bash script I am trying to execute is the following:

#!/bin/bash

while [ 1 ]
do
if [$(ls /home/arch | grep check)="check"]; then
/home/arch/shutdownServer1
fi
done

I tried to execute the code while the folder named "check" was available in the folder "/home/arch" But I got the following error.

/home/arch/myscript: line 5: [check=check]: command not found => This implies that the expression "$(ls /home/arch | grep check)" was evaluated correctly because of check=check. But why does it say "command not found"? Since check=check it should be evaluated as true and execute the script shutdownServer1?

P.S.: myscript is the name of the bash script file.

Guys, please help me.

Thanks in advance

if [ -d /home/arch/check ]; then

Try one of these

if [ $(ls ~/ | grep check) ]; then
    ~/shutdownServer1
fi

or

[ $(ls ~/ | grep check) ] && ~/shutdownServer1

Edit: @Allan: thanks for '-d', I completely forgot that

Not that using the grep like that, any file with "check" anywhere in its name will set off the script...

I would suggest to have a look at incrond [1] , what does exactly what you need.
