I have tried to ssh to multiple vms. I used for loop. I want to fetch the username and IP and loop into multiple VMs.
export IFS=","
for read f1 f2 in $(cat sample.txt);
do sshpass -p 'password' ssh $f1@$f2 "uname -a" ;
done
sample.txt contains
abc,111.111.111.111
def,111.222.333.444
Looks like I am facing an error,
syntax error near unexpected token f1'
for read f1 f2 in $(cat LNodeInput.txt);'
I have tried it in few other ways too but still throws an error.
#!/bin/bash
while IFS="," read -r f1 f2
do
sshpass -p 'password' ssh "$f1@$f2" "uname -a" < /dev/null ;
done < sample.txt
be careful sample.txt should have the last line as empty line, otherwise it will not read the last line of it.
EDIT:
< /dev/null is to stop ssh from "eating" input from sample.txt. Otherwise, the command will only ssh to the first server.
sample.txt file? pls be careful about that(as I mentioned in my answer)for a in `cat servers`;do echo ;echo $a ; sshpass -p 'password' ssh $a uname ; done
Like this what ever u want u can add before done.. If u want an output collected in a file add > file1 at the end
fordoesn't work that way, change towhileand you'll be very close. Good luck.
