ssh-agents prints details about its config (i.e. where ssh should search authentication agent) - and thats all. (these are SSH_AUTH_SOCK et al.) eval `` in turn takes these statements and try to evaluate them (i.e. creates these two variables in environment) as an example try --8<---------------cut here---------------start------------->8--- $echo "KJONCA_VAR=this_is_test" $set | grep KJONCA $eval $(echo "KJONCA_VAR=this_is_test") $set |grep KJONCA --8<---------------cut here---------------end--------------->8--- KJ -- http://stopstopnop.pl/stop_stopnop.pl_o_nas.html
