I Have a unix shell script, after it runs, it will ftp a file to windows server. Then i need to manuallu schedule a windows batch script. couls you please suggest me method where i can call the batch script from the unix shell script.
Thanks in advance
Take a look at this:
https://stackoverflow.com/a/16720186/2471910
It talks specifically about invoking a windows program from another windows machine (instead of a unix machine) but the concepts are the same since ssh is available on unix as well.

I am using a Linux Workstation to run my R script. I did so using screen and then Rscript myRscript.R. Is there anyway to access the R session after the script has run? I want to be able to write new commands and access the global environment that was created during that session.
I tried asking the Unix community, but no response...
https://unix.stackexchange.com/questions/608073/how-to-pass-code-to-attached-screen
The session is lost after the script is done running. But you can save the environment using save.image("env_file.Rdata") and use it later using load("env_file.Rdata").
See http://ugrad.stat.ubc.ca/R/library/base/html/save.html
I am using SSHLibrary to Open Connection and Log In to a machine which doesn't use the standard Linux Shell. After having logged in to that machine, to use the Linux shell I run the command shell and then provide a username and password to connect to it, using SSHLibrary's Write.
So far so good, but then how can I continue writing to the shell I just opened? Continuing to use Write Commands to execute something like ls doesn't seem to work.
The Keyword Connect to SDWAN Shell is the one I used to connect to the new shell. The new shell opens by Writing the credentials but the next Write which is the ls command doesn't seem to work.
I have one .bat script on my windows share that is mounted to my UNIX machine. Bat script is set to make file transfer between 2 windows shares, but I would like to trigger this script from a unix machine if that is possible. I was reading that you can do it with wine or dosbox, but I don't have that installed on my unix. Is it possible to resolve this problem with some additional .sh script that will trigger my .bat script correctly?
Thank you in advance.
Best regards.
You cannot run a .bat script on a Unix machine for several reasons :
Unix has not the same commands (on the command line) as Windows. The POSIX standard defined a set of commands, if you use them you'll be portable on various POSIX systems (but not on Windows); for example to list a directory, you'll use DIR on MSDOS and Windows but ls on Unix and POSIX; to copy a file it is COPY on MSDOS and Windows but cp on Unix and POSIX; etc....
Unix has not the same command interpreter as Windows. The POSIX standard and the Unix tradition provides a Unix shell and POSIX has standardized /bin/sh (a.k.a. POSIX shell). Windows has CMD (inherited from MSDOS) and PowerShell.
The way of interpreting commands is different (on Windows look also into PowerShell, which I don't know). On Unix it is the shell (not the invoked programs) that is expanding your command and globbing. See this answer for more. The notion of current working directory is different.
the operating system concepts are (slightly or significantly) different on Windows and on Unix or POSIX. For example, files, directories, processes, libraries are different (for example, a file can be written by a process and removed by another one on Unix and it can have several names on Linux thru hard links), .... etc.... You could read Operating Systems: Three Easy Pieces for an overview.
the Unix philosophy is not (always) applicable to Windows.
So you need to study Unix (or POSIX) and write your own shell script from scratch. Don't try to "translate" a bat script to a Unix shell script, but redesign it entirely (starting from the problem you want it to solve).
(and Wine or DosBox is not helpful in your case)
Read also about SCP and perhaps FTP. Perhaps using some distributed version control system like git could be relevant for you (e.g. to share scripts, source code, etc...).
If you need to run remotely some Windows .bat script on a distant Windows machine (e.g. from a Unix machine), you should use some remote command running service (that is, find and use some equivalent of SSH service on Windows, and use the corresponding client on Unix). See this.
So if you need to remotely run on a Windows server something (e.g. some program, some script, some command) from a Unix machine you should ask a different question (or at least improve a lot the current one).
Read about the client-server model and about application layer to use the correct terminology. You should name what protocol, server, client, service you want to involve. Nothing is magically "triggered" without using them.
PS. I'm using Unix since 1987, Linux since 1993. I never used Windows.
I'm using PuTTY to connect to a zOS mainframe (running USS, IBM's Unix-compatible software) and I'd like to download a hex dump (using od) of a file without making a copy of it on the filesystem. Is there a way that I can save or pipe stdout (through PuTTY) directly to a file on my (Windows XP) client?
You could configure session logging for your PuTTY session, as per the documentation. Then just run od on the server, wait until it finishes, and then close your log file. You'll need to trim the cruft at the beginning and end (because it has your whole session), but you should end up with what you want.
Note that upon inspection that documentation link may be for an older version of PuTTY, so YMMV but I'm sure that more recent versions also support session logging.
If you were to install a command-line ssh tool (e.g., running OpenSSH under Cygwin), you could then do the standard "ssh hostname command > file" sort of redirection.
i am working on unix.
i want to write a shell script which will check for a file called "temp_file.txt" on windows
and then execute some commands.
is this possible?
how could we connect to the windows and go to a specific directory and check for a file?
Share the directory on the Windows machine using the "regular" Windows file sharing facilities. On the Linux side, you have two options:
Use smbclient to connect to the Windows machine and check if the file exists or
Use smbmount to mount the shared directory into your Linux file system and check file existence using "standard" Linux commands (e.g. test).
The exact implementation details will depend on the scripting language that you use, but your pseudo-code will look something like this:
loop:
check if file exists
if yes: do something useful
sleep for some reasonable time
(I am assuming that you want to execute the commands on the Linux machine.)
If you're using Linux (you specify that you're using Unix, but not what variant), check out the inotify API --- this will allow you to set up event responders for filesystem events (much more efficient than polling).
From a shell script, you can use the inofitywait command --- see http://linux.die.net/man/1/inotifywait for more information.
you could set up SSH on Windows and then write a script on Unix using the SSH client to connect to Windows and execute the command. The alternative, if you can afford to, it to write a windows batch, and execute your command on Windows itself. Or you can turn on Windows terminal services, and use telnet protocol from Unix to issue the command. Programming languages that support telnet includes Perl (Net::Telnet) and Python(telnetlib)
As ghostdog74 suggested, ssh is your best bet. You can run something like (I assume you have Cygwin or SFU installed)
ssh "[ -e $file ] && do_something.sh" > do_something.log
If your command logs to stdout, you get the log on your Linux box as well.
If you set up private key authentication, it gets even better.
