Top Forums Shell Programming and Scripting Execute commands from script in current bash session Post 302437469 by jelloir on Thursday 15th of July 2010 07:41:43 AM

Thanks dr.house!

However using $HOST overwrote my shells default $HOST and broke the script and my shells $HOST env.

I changed it to the variables I had originally and it works a treat.

Nice Smilie

Edit: actually I'm talking rubbish sorry, its becuase you used HOST twice as a variable.

I ended up putting this in, which works:

Code:
for SSHHOST in $( cat /etc/mxg/ssh-hosts )
do
  SSHALIAS=$( echo $SSHHOST | awk -F "." '{print $2}' )
  SSHHOSTNAME=$( echo $SSHHOST | awk -F ":" '{print $1}' )
  SSHPORT=$( echo $SSHHOST | awk -F ":" '{print $2}' )
  alias $SSHALIAS\="ssh -p $SSHPORT $SSHHOSTNAME"
done

Regards

Net::Time(3pm)						 Perl Programmers Reference Guide					    Net::Time(3pm)

NAME
Net::Time - time and daytime network client interface SYNOPSIS
use Net::Time qw(inet_time inet_daytime); print inet_time(); # use default host from Net::Config print inet_time('localhost'); print inet_time('localhost', 'tcp'); print inet_daytime(); # use default host from Net::Config print inet_daytime('localhost'); print inet_daytime('localhost', 'tcp'); DESCRIPTION
"Net::Time" provides subroutines that obtain the time on a remote machine. inet_time ( [HOST [, PROTOCOL [, TIMEOUT]]]) Obtain the time on "HOST", or some default host if "HOST" is not given or not defined, using the protocol as defined in RFC868. The optional argument "PROTOCOL" should define the protocol to use, either "tcp" or "udp". The result will be a time value in the same units as returned by time() or undef upon failure. inet_daytime ( [HOST [, PROTOCOL [, TIMEOUT]]]) Obtain the time on "HOST", or some default host if "HOST" is not given or not defined, using the protocol as defined in RFC867. The optional argument "PROTOCOL" should define the protocol to use, either "tcp" or "udp". The result will be an ASCII string or undef upon failure. AUTHOR
