SSH in batch mode and File-Handles in a loop
Hi all
I try to execute SSH commands on several hosts in a while-loop.
There seems to be a problem with file-handle, first cycle works correct but no other one will follow due to the while condition is false even that there are many more host entries (lines) in all_hosts.dat.
#!/usr/bin/ksh
exec 0<all_hosts.dat
while read line
do
echo "...executing on host :" $line
ssh $line 'ls -la /tmp' # execution aborts after the first cycle
###pwd | ssh $line 'ls -la /tmp' # continues for each entry of all_hosts.dat
done # <all_hosts.dat
#
Any clue?
Any pointer to explaining tutorials about file handles?
