In interactive mode, I do
pbrun su - privuser
rm dir1
But if I run above commands in a bash script file, I'll simply receive a new bash terminal window after the first command.
Is it possible use pbrun in a script file?
yes, You can use pbrun and su command in your bash script.but before that
pbrun - It is a secured terminal command where
sudo- is secured user instead of terminal.
So, If you have valid credentials, you can use below command
pbrun -u [username] dap --> syntax
Try using " pbrun -u privuser" --> It might work

I am using lftp to connect to SFTP server using the below in a shell script.
host=testurl.url.com
user=username
pass=pass
lftp<<EOF
open sftp://${host}
user ${user} ${pass}
cd test/myfolder/
bye
EOF
when executing the above using a shell script, the script exits but I am not sure if a connection is established and I don't see the output of my cd command which I executed within lftp.
Is there a way to output to a log file to see if connection is successful and the output of cd command.
Thank you.
I added a ls to the list of commands and I was able to list the directories
host=testurl.url.com
user=username
pass=pass
lftp<<EOF
open sftp://${host}
user ${user} ${pass}
cd test/myfolder/
ls
bye
EOF
I want to run multiple commands automatically like sudo bash, ssh server01, ls , cd /tmp etc at server login..
I am using Remote command option under SSH in putty.
I tried multiple commands with delimiter && but not working.
There is a some information lacking in your question.
You say you want to run sudo bash, then ssh server01.
Will sudo prompt for a password in your remote server?
Assuming there is no password in sudo, running bash will open another shell waiting for user input. The command ssh server01 will not be run until that bash shell is exited.
If you want to run 2 commands, try first simpler ones like:
ls -l /tmp ; echo "hi there"
or if you prefer:
ls -l /tmp && echo "hi there"
Does this work?
If what you want is to run ssh after running bash, you can try :
sudo bash -c "ssh server01"
That is probably because the command is expected to be a program name followed by parameters, which will be passed directly to the program. In order to get && and other functionality that is provided by a command line interpreter such as bash, try this:
/bin/bash -c "command1 && command2"
I tried what I suggested in my previous answer.
It is possible to run 2 simple commands in putty separated by a semicolon. As in my example I tried with ls and echo. The remote server runs them and then the session closes.
I also tried to ssh to a remote server that is configured for not asking for a password. In that case, it also works, I get connected to the 2nd server and I can run commands on it. Upon exit, the 2 connections are closed.
So please, let us know what you actually need / want.
You can execute two consecutive commands in PuTTY using a regular shell syntax. E.g. using ; or &&.
But you want to execute ssh server01 in sudo bash shell, right?
These are not two consecutive commands, it's ssh server01 command executed within sudo bash.
So you have to use a sudo command-line syntax to execute the ssh server01, like
sudo bash ssh server01
I would like to run a command on a remote server using ssh, under bash, while my default session is csh.
minimal example (true command is more complex and is generated by my IDE remote debugger):
ssh hostname 'ls | head'
I don't have admin privileges. Trying chsh -s /bin/bash results with an error chsh: cannot lock /etc/passwd; try again later.
I tried adding to .cshrc the following
setenv SHELL /bin/bash
exec /bin/bash --login
but it freezes the console when sending the command through ssh (while regular ssh works)
Any idea how to solve that?
NOTE: I must have a solution that would configure the host, because I don't have access to the ssh command which is generated automatically by the debugger of my IDE. On the IDE I can only set the host name and port number. (EDIT) Therefore solutions like ssh hostname '/bin/bash -c "ls | head"' wont apply
EDIT2:
Actual command shown by IDE (again, I can't edit it):
ssh://username#localhost:2213/home/lab/username/anaconda2/envs/tf_011b/bin/python -u /specific/a/home/cc/cs/username/.pycharm_helpers/pydev/pydevd.py --multiproc --qt-support --client '0.0.0.0' --port 41823 --file /home/lab/username/remote_py/nlteach/show_attend_and_tell/train_saat_classifier.py --train_dir=/home/lab/username/nlteach/output/train/d=cub/imSD=11%imSP=rnd%tcSP=cvpr16/CSat/res50%lr0_02LrDTexpLrDc0_938OrmspWDc0/emb=512%ldTrn=0%nU=512%noHid=1%lr=0_02%lrDT=fix%lrDc=1%o=rmsp/
I am not sure why, but on a bash enabled server it works, while it fails on the csh host.
Thanks!
Invoke bash on the remote side, telling it what commands to run:
ssh hostname '/bin/bash -c "ls | head"'
If the command is too complicated (eg because of quotation mark escaping), then write your commands to a script, copy the script, then run the script:
scp script.bash hostname:/tmp/
ssh hostname '/bin/bash /tmp/script.bash'
I have already looked at the following links but didn't managed to make it work:
SSH to server, Sudo su - then run commands in bash
Can I ssh somewhere, run some commands, and then leave myself a prompt?
Run ssh and immediately execute command
I'm trying to automate the following sequence to log in to the database
$ ssh <myserver>
me#myserver$ sudo su - oracle
<enter password>
oracle#myserver$ bash
oracle#myserver$ export ORAENV_ASK=NO
oracle#myserver$ export ORACLE_SID=ORACLEDB
oracle#myserver$ . oraenv
oracle#myserver$ echo $ORACLE_HOME
I tried the command (based on the links above) but that does not work :
ssh -t myserver "echo password | sudo -S su - oracle ; bash ; export ORAENV_ASK=NO"
How can I combine thoses commands in a shell script (or even perl one), execute it and then leave myself at a prompt so I can run sqlplus after? Is that even possible?
Note:
ssh does not need password because we use authorized_keys, BUT Password-less sudo is not an option nor using su directly (I'm not root and cannot change that), the command needs to be "sudo su - oracle" exactly.
Thanks
You can't do that in shell, but you can do it with expect (apt-get install expect if on Debian variants).
This is a very simple expect file. You need to do some research to make it work in your environment but this gives the general idea.
spawn ssh foo#x.x.x.x
expect "~$"
send "sudo bash\r"
expect {
password {send "foobar\r";exp_continue}
"#"
}
send "id\r"
expect "root"
You would run this as expect /path/to/your/expectfile.
This will log in, do sudo with password "foobar", execute id and exit. Would this be of any help?

I am working on Automating deployment script for which I have to run all steps as sudo user, when I try to sudo first in my script like below it prompt me for password and then rest of script doesn't execute, when i exit sudo then only it executes.
"sudo -u username bash"
Please help me how to achieve this or I have to first login using sudo and then only run my script ?
You can instead just run the script as sudo.
sudo sh ./script.sh
This way the entire script would run as a sudo user, and it would prompt only for once.
If you want to still use sudo -u you can use it like this, instead of:
sudo -u username bash
You can do:
sudo -u username sh ./script.sh
