#Transfer file putty ssh password
I’ve tested against multiple target hosts, and sometimes I am able to echo the password to sudo from inside the script file, but other times the password prompt for sudo has to be provided at the ssh client console.Īpproach 1: Sudo password echoed and embedded inside plink script But many times the commands we want to run in batch processes require sudo, which throws up an interactive prompt for a password. In the above example we dealt with simple commands that required no input and no privilege escalation with sudo (hostname, pwd). Then plink could be invoked like: > plink.exe -ssh -t -pw myP4ss -m plink-script.txtīut just like pscp, if the host key was not cached in the registry yet, you would get an interactive prompt saying “Store key in cache? (y/n)” which would not be conducive to a batch script.Īnd once again, the way around this is to pipe a “y” to stdin, which makes the command: > cmd.exe /c echo y | plink.exe -ssh -t -pw myP4ss -m plink-script.txt plink and sudo with password prompt If you had a text file named “plink-script.txt” with the content below it would print out the hostname, tell you the name of the current directory, and then list the files in /tmp. Valid commands include anything you could type from a normal ssh client. Plink is able to ssh into a host and run a set of commands using the following syntax: > plink.exe -ssh -t -pw -m > cmd.exe /c echo y | pscp.exe -pw myP4ss README.txt plink.exe for ssh commands If you issued the same command but piped a “y” to the stdin, it would answer the prompt for you. You would be forced to press either y/n before moving on, and this is something the Putty developers want because of security concerns, but it also hampers automation. > pscp.exe -pw example, if you were moving a text file named README.txt to /tmp of a remote host named ‘trusty1’ as the user ‘myuser’, the command could look like below: > pscp.exe -pw myP4ss README.txt this command would give the interactive prompt “Store key in cache? (y/n)”. Pscp.exe takes parameters very similar to the Linux based scp. These clients can be used to run file transfers and commands against hosts in console mode, perfect for automation of repetitive tasks. It also has pscp.exe, a command line scp client, and plink.exe which is a command line ssh client. These represent shortcuts to certain commands and are activated using the corresponding function key (i.e F1 for help, F5 to copy, etc).The Putty suite contains several executables beyond the main application. You can even use your mouse to select files and function keys to execute commands.Īs you can see on the screenshot, there are numbers from 1 to 10 at the bottom of the console screen. You can easily copy/move files from the left side directory to the right side using a semi-visual approach. Once inside the application you will see two sections – left and right. All our servers have mc installed and it is available by executing the mc command using the SSH Shell. To overwrite already existing files you should use the -f argument: cp -Rf includes/ admin/includes/Ī more convenient way to copy files/folders is to use a 3rd party application, such as Midnight Commander. R instructs cp to copy files recursively (for example, a whole directory).
The command will copy the original_file file to new_file and will preserve the original one (the file will NOT be removed after it is copied).Ĭp also accepts various arguments: cp -R includes/ includes_backup/
The copy ( cp) command works the same way as mv, but instead of moving the files/folders it copies them.
#Transfer file putty ssh update
In some cases, however, you will need to only update and move only files that were changed, which you can do by passing -u as an argument to the command: mv -u includes/* admin/includes This will move all files (and folders) from the includes/ directory to the current working directory. You can also use mv to move a whole directory and its content: mv includes/*. The mv command syntax looks like this: mv original_file new_nameīy executing the above command you will move (rename) the file original_file to new_name. The commands which you would need to use are mv (short from move) and cp (short from copy). Often you will need to move one or more files/folders or copy them to a different location.
