Re: sending hundreds of commandos on SSH connection

[JGmonk]

Guys you are really quick. I changed the grep statement as written by "hazylife". Added saving to file. About the answers from "kennethk" und "zentara" i need to expand my horizon the next days. For testing it now with looping up to 20 times, i just added a sleep() (temporarely). The script will run after normal working hours of the server at night. So itīs not needed to be as quick as possible.

fgrep -v +1900

That should probably be fgrep -v 1900

Appendix: I get this error on every executed statement from the remote host
"tput: No value for $TERM and no -T specified"

somebody knows what to add on the ssh connection to get rid of it?
