Shell Programming and Scripting

Your script can't read from stdin. That's already being used to feed in the script, so your read commands eat part of the script.

Pass in variables into it like I showed you instead. They will be $1, $2, etc.

i tried this .. not sure if i followed u correctly.. or missing something.

Code:

case $Env in
        1)         export Env=devl
            export User=ecifetld
            # mkproj_dirs "/webdata/ecif/etl/$Env/$projectname/"
            export Env=$1
            export projectname=$2
            ssh $User@boom.nwie.net exec /bin/bash -s "'$1'" "'$2'" < mkdir_infor.sh

Got same error ... pls advice

Why do you have ssh inside the script when you're running this script on another server? I think you've gotten very confused along the way. Do all the ssh-es on the local side.

That's why I suggested doing what I did originally.

Code:

ssh username@host mkdir "'/path/to/whatever'" ';' tar -C "'/path/to/whatever'" -xf - < file.tar

Run that locally to create directories on the remote host. That should be all you need.

i am running script mkdir_infor.sh on remote server .Do you want me to copy this script on remote server to create the directories .. It would like copying script on env servers..
Any other suggestions..!
Thanks

Is it really your intent to ssh from server A into server B, so that server B can ssh into server C, to create directories on it? Why not just ssh into server C in the first place?

I think you've misunderstood the purpose of what I've suggested. You need to run these things on the local host. It makes no sense to run them anywhere but the local host. These commands log into the remote host and to the job you asked for -- creates directories on the remote host. By just dumping parts of what I've shown you in the middle of a script to be run on the remote host you're really changing the meaning of it.

I've shown you what you need to do. It's not an element of something you need to run anywhere else. It ought to work when run on the local host, allowing you to create directories on the remote host, as long as you've created a tar file like I illustrated earlier.

Code:

# Run this on the local host, to log into username@host and create directories in /remote/path/$ENV/whatever
ssh username@host mkdir "'/remote/path/$ENV/whatever'" ';' tar -C "'/remote/path/$ENV/whatever'" -xf - < ~/file.tar

Have you tried it yet? Not as part of a script, not sending it to the remote host, not anything but running this exact line on the local host with the paths you want on the remote host.

Does it work? Yes or no?

If not, in what way?

I intent to ssh server B from Server A and then create directories in server B.

Sorry, But i am not able to understand the code u suggested .
"# Run this on the local host, to log into username@host and create directories in /remote/path/$ENV/whatever
ssh username@host mkdir "'/remote/path/$ENV/whatever'" ';' tar -C "'/remote/path/$ENV/whatever'" -xf - < ~/file.tar"

It runs two commands on the remote server.

1) mkdir /remote/path/$ENV/whatever
2) tar -C /remote/path/$ENV/whatever -xf - < ~/file.tar

They are separated by ';', which will be fed into the other end as simply ;, as a separator between two shell statements. If you didn't put quotes around it, your shell would attempt to run tar on localhost instead of feeding the command into ssh...

The 1) command creates the base directory you want.

The 2) command extracts the tarball you made, of all the subdirectories with the permissions you wanted, inside /remote/path/$ENV/whatever. It reads from standard input.

~/file.tar, a file on the local host(not the remote host!), is the tarball I showed you how to create before. It is redirected into the standard input of ssh, so tar on the other end can read it from its own standard input without having to keep the file on the remote host.

All you have to do is substitute your own variables and filename into it, then run it locally.
