I'm trying to make a script that automatically zips a file with a password. Zip does this by asking for a password in an interactive prompt. How do I make the script respond to the prompt?
I've tried:
zip -e xxx myfile
Enter password:
zip error: Interrupted (aborting)
zip -e myfile < xxx
-bash: xxx: No such file or directory
The -e option expects that zip is running on a terminal. You can use a pseudo-terminal and script that (using the Expect package available in Tcl or Perl or something similar) if you don't mind the complexity.
It might be easier to use the -P flag (or --password) flag with zip, and just pass the password on the command line.

In the putty manual outlines how to use the program with command line parameters. I have this setup with a shortcut on my toolbar to automatically log me into my server.
"C:\Program Files\PuTTY\putty.exe" username#server -pw .... -C
However, I'd like to run a simple script to automatically put me in a specific directory once I log in. I saw there's the -m command to give "a local file name, and it will read a command from that file".
With a file at the destination I've tried the following options:
"C:\Program Files\PuTTY\putty.exe" username#server -pw .... -C -m "C:\local file\script.txt"
"C:\Program Files\PuTTY\putty.exe" username#server -pw .... -C -m "C:\local file\script.sh"
"C:\Program Files\PuTTY\putty.exe" username#server -pw .... -C -m "/server/file/with/755/permissions/script.sh"
And nothing worked.
I'm trying to find an example of this parameter and use but I can't find one. How can I properly use this parameter.
Quoting the docs,
The -m option performs a similar function to the ‘Remote command’ box in the SSH panel of the PuTTY configuration box (see section 4.19.1). However, the -m option expects to be given a local file name, and it will read a command from that file.
And quoting section 4.19.1,
In SSH, you don't have to run a general shell session on the server. Instead, you can choose to run a single specific command (such as a mail user agent, for example). If you want to do this, enter the command in the ‘Remote command’ box.
Note that most servers will close the session after executing the command.
Note the "instead". This is not a command to run in the shell before passing control to you. This is a command to run instead of a shell.
You can't just put cd /wherever and expect to end up in a shell in directory /wherever. You might be able to write a command that will run a shell in the directory you want and give you control, though I'm not sure how to get all the details correct.
I'm currently setting up a batch file to ssh from a Windows machine into a Ubuntu machine and issue a series of commands. I'm using plink, and I'm using the -m argument to pass a .txt file with a list of commands.
The batch file code that runs through cmd:
set PATH=c:\path\to\plink.exe
plink.exe -ssh -t user#ipaddress -pw <psw> -m c:\path\to\textFile\commands.txt
The commands.txt code:
sudo -s #access the root login
<root psw> #enter the password for the root login
command-1 #issue a command in linux as root
command-2 #issue a command in linux as root
command-3 #issue a command in linux as root
The issue I'm running into is that when I run this batch file, the output within command prompt still prompts the user to manually enter the password. Is there a means to input the password form the next line of the commands.txt file? Or does this process require something else?
As even your question says, the file commands.txt specified by -m switch should contain commands. A password is not a command.
Moreover, the commands in the file are executed one-by-one. The sudo (had it worked) would execute an interactive shell session and wait for a user input (commands). Only once the sudo exits, the following commands (command-1, etc) are executed.
Automating password input for sudo is generally a bad idea. If you need to run some commands that require root privileges, a better solution is to associate a dedicated private key with the commands in sudoers file. And then use sudo and the private key in Plink.
Anyway, to automate an input (of a password in this case) to a command, you need to use an input redirection. The same is true for commands to be executed within (not after) sudo.
Like:
(
echo passwod
echo command-1
echo command-2
) | plink.exe -ssh -t user#ipaddress -pw <psw> sudo -s
As now there's only one real top-level command - sudo, I'm specifying it directly on Plink command-line, instead of using -m switch. Functionally, it's identical.
I have 2 Linux boxes and i am trying to upload files from one machine to other using sftp. I have put all the commands I use in the terminal to she'll script like below.
#!/bin/bash
cd /home/tests/sftptest
sftp user1#192.168.0.1
cd sftp/sftptest
put test.txt
bye
But this is not working and gives me error like the directory does not exist. Also, the terminal remain in >sftp, which means bye is not executed. How can I fix this?
I suggest to use a here-document:
#!/bin/bash
cd /home/tests/sftptest
sftp user1#192.168.0.1 <<< EOF
cd sftp/sftptest
put test.txt
EOF
When you run the sftp command, it connects and waits for you to type commands. It kind of starts its own "subshell".
The other commands in your script would execute only once the sftp command finishes. And they would obviously execute as local shell commands, so particularly the put will fail as a non existing command.
You have to provide the sftp commands directly to sftp command.
One way to do that, is using an input redirection. E.g. using the "here document" as the answer by #cyrus already shows:
sftp username#host <<< EOF
sftp_command_1
sftp_command_2
EOF
Other way is using an external sftp script:
sftp username#host -b sftp.txt
Where, the sftp.txt script contains:
sftp_command_1
sftp_command_2
I have a shell script, which I am using to access the SMB Client:
#!/bin/bash
cd /home/username
smbclient //link/to/server$ password -W domain -U username
recurse
prompt
mput baclupfiles
exit
Right now, the script runs, accesses the server, and then asks for a manual input of the commands.
Can someone show me how to get the commands recurse, prompt, mput baclupfiles and exit commands to be run by the shell script please?
I worked out a solution to this, and sharing for future references.
#!/bin/bash
cd /home/username
smbclient //link/to/server$ password -W domain -U username << SMBCLIENTCOMMANDS
recurse
prompt
mput backupfiles
exit
SMBCLIENTCOMMANDS
This will enter the commands between the two SMBCLIENTCOMMANDS statements into the smb terminal.
smbclient accepts the -c flag for this purpose.
-c|--command command string
command string is a semicolon-separated list of commands to be executed instead of
prompting from stdin.
-N is implied by -c.
This is particularly useful in scripts and for printing stdin to the server, e.g.
-c 'print -'.
For instance, you might run
$ smbclient -N \\\\Remote\\archive -c 'put /results/test-20170504.xz test-20170504.xz'
smbclient disconnects when it is finished executing the commands.
smbclient //link/to/server$ password -W domain -U username -c "recurse;prompt;mput backupfiles"
I would comment to Calchas's answer which is the correct approach-but did not directly answer OP's question-but I am new and don't have the reputation to comment.
Note that the -c listed above is semicolon separated list of commands (as documented in other answers), thus adding recurse and prompt enables the mput to copy without prompting.
You may also consider using the -A flag to use a file (or a command that decrypts a file to pass to -A) to fully automate this script
smbclient //link/to/server$ password -A ~/.smbcred -c "recurse;prompt;mput backupfiles"
Where the file format is:
username = <username>
password = <password>
domain = <domain>
workgroup = <workgroup>
workgroup is optional, as is domain, but usually needed if not using a domain\username formatted username.
I suspect this post is WAY too late to be useful to this particular need, but maybe useful to other searchers, since this thread lead me to the more elegant answer through -c and semicolons.
I would take a different approach using autofs with smb. Then you can eliminate the smbclient/ftp like approach and refactor your shell script to use other functions like rsync to move your files around. This way your credentials aren't stored in the script itself as well. You can bury them somewhere on your fs and make it read only by root an no one else.
I am using plink to execute the shell script on the remote MachineB. And shell script is there on the MachineA(Windows Box).
C:\PLINK>plink uname#MachineB -m test.sh
Using keyboard-interactive authentication.
Password:
Using keyboard-interactive authentication.
Your Kerberos password will expire in 73 days.
And that shell script generates the output in a text file(aa.txt) on MachineB and that gets stored in /export/home/uname/aa.txt
So my question is- Is there any way that I can copy the aa.txt file from MachineB to MachineA as soon the script has completed all its task using the ssh. Or we need to put all these things in Windows Batch file?
So Problem Statement is like this-
Execute the shell script on MachineB from MachineA.
Then wait for the shell script to complete its task, in my case it will write the output to a text file.
And after the shell script has completed all its task means it finished writing everything to a txt file, then copy that txt file to MachineA from MachineB
Any suggestions will be appreciated on how I can achieve the above scenario?
Update:-
So Suppose if this is the content in test.sh shell script file and also after adding pscp at the end of script, then it should be like this?
#!/bin/bash
export HIVE_OPTS="$HIVE_OPTS -hiveconf mapred.job.queue.name=hdmi-technology"
hive -S -e 'SELECT count(*) from testingtable2' > aa.txt
pscp uname#MachineB:/export/home/uname/aa.txt c:\documents\foo.txt
So I am executing a hive query in the above script and whose output is getting stored in aa.txt file and as soon as the query is completed and output is stored in aa.txt file, it will go to fourth line of pscp which will transfer aa.txt file to my local windows machine inside documents folder. Am I right? This will be the whole process?
And if the above process is right as far as I understood, then I can simply go to windows cmd prompt, and do like below and it will do the exact same process. Right?
C:\PLINK>plink uname#MachineB -m test.sh
Using keyboard-interactive authentication.
Password:
Using keyboard-interactive authentication.
Your Kerberos password will expire in 73 days.
Updated Again:-
So I need to create a bat file, and suppose this is the below test.bat file, so content should be like this in that test.bat file-
plink uname#MachineB -m test.sh
pscp uname#MachineB:/export/home/uname/aa.txt c:\documents\foo.txt
You can use scp to download the file after execution. If you setup winsshd on your windows machine and append a copy command in the test.sh file:
scp /export/home/uname/aa.txt user#windowsmachine.com:/homedir
The file will be transferred after completion.
Similarly, you can use a windows scp client like pscp on your windows machine, you can pull the file from the linux machine:
pscp uname#MachineB:/export/home/uname/aa.txt c:\documents\foo.txt
So on windows machine, have a batch script:
plink uname#MachineB -m test.sh
pscp uname#MachineB:/export/home/uname/aa.txt c:\documents\foo.txt
Just to add on to what has already been said, I am running something very similar and use the following format (from a batch script):
plink -ssh user# -pw password -m yourScript.sh
pscp -sftp -pw password user#IP-Address:/path/to/remote/file C:\path\to\local\save\directory
That second command is on one line, but it might not render like that on here. Of course, replace IP-Address, user, and password with the appropriate values for your login :-)
Hope that helps!
EDIT - Sorry, just realized this EXACT answer was already given. Kudos!
