rm to exclude file

hilou · 04-06-2016, 02:53 AM

I am using !(filename) sytax to exclude file from rm command.

It's working when I run it directly in bash.

But not working when used in a ssh command like below:

ssh 10.23.10.138 'rm -rf /tmp/td/d1/d2/!(*.py)'
bash: -c: line 0: syntax error near unexpected token `('
bash: -c: line 0: `rm -rf /tmp/td/d1/d2/!(*.py)'

Can someone tell me why ?

Thank you in advance!

run: shopt -s extglob

then try running the command again it should be okay.

to turn off: shopt -u extglob

Login first and run bash as local.

Nope, tested not working.

I will need to run this in a script.

Put and run the script in the host remote machine.

I think the sshd is getting confused between a command and a shell...

You might try

Code:

ssh 10.23.10.138 bash -c 'rm -rf /tmp/td/d1/d2/!(*.py)'

Same error!

as Jpollard suggested try double quotes:

You might also include "-v" in the bash options so that you can see what command line actually got passed.

You probably need to use single-quotes to enclose the command, which then itself includes quotes to tell the shell on the other side not to do its own expansion.

But I admit that I'm getting a little froggy about this. I'd use ssh to execute some sort of script on the remote side which does your bidding.
