Sample shell script to copy files




















Just to help avoid confusion with copy-paste usage of this solution, currently this answer seems to transfer FROM remote TO local -- which is opposite to what the OP is looking to do. Ciabaros good catch! I updated the answer.

The nice thing about scp ist that it uses a secure channel. Thanks, I was right in the middle of adding that update and got distracted.

This will still invoke an interactive password prompt. I believe the OP wanted a fully automated solution — Tom Auger. Dimitri scp -r copies files recursively. It has nothing to do with storing a password within the script and passing it to the scp call via a bash script! I don't really understand your comment.

Can expect be used for rsync? I am trying to do something and my RSA key method is not working. It keeps asking me the password for the remote machine. Thanks a lot Prudhvi.. Hi Prudhvi, All the articles in the site are very helpful and confidence boosting for beginners. Regards, BalaKrishna Reddy Avuthu. Great article. Previous post XML Publisher. For fetching all the files and dir from a specific path, we will use for loop in the script then filter out the only file using if condition.

In the example below, we execute the cp command only executed if the iterator was a file which is determined -f flag.

In this example, we will copy all the files with the. In this example, we will copy all the files, including directories, recursively. For that, we simply need to add -R cp command where -R determines recursively fetching of the directory.

In this example, we will copy files from user-specified dir. To do so, we will use the read command to request the path from the user then check if the user provides the path to dir or not, which is done by the -d flag in the condition.

After verifying dir, we will use a for loop to iterate all the files and dir inside the given path, then again filter out the only files using the if condition. The following examples show this in action. However, omitting the will result in string concatenation rather than addition. So, check for things like this in your program.

As with any programming dialect, functions play an essential role in Linux shell scripts. They allow admins to create custom code blocks for frequent usage. The below demonstration will outline how functions work in Linux bash scripts. So whenever you need to add again, you can just call this function instead of writing that section again. One of the most fantastic functions is allowing the passing of data from one function to another.

It is useful in a wide variety of scenarios. Check out the next example. The ability to run system commands using shell scripts allows developers to be much more productive. The following simple example will show you how to create a directory from within a shell script. This script simply calls your standard shell command mkdir and passes it the directory name if you look closely. This program should create a directory in your filesystem. The above program will not work if your current working directory already contains a folder with the same name.

Bash scripts allow users to read files very effectively. The below example will showcase how to read a file using shell scripts. First, create a file called editors. The following program will demonstrate how to delete a file within Linux shell scripts. The program will first ask the user to provide the filename as input and will delete it if it exists. The Linux rm command does the deletion here. It should delete the file. The below shell script example will show you how to append data to a file on your filesystem using bash scripts.

It adds an additional line to the earlier editors. It is quite straightforward to send emails from bash scripts. The following simple example will demonstrate one way of doing this from bash applications. The next bash script example will show you how to handle dates and times using scripts.

Again, the Linux date command is used for getting the necessary information, and our program does the parsing. The sleep command allows your shell script to pause between instructions. It is useful in a number of scenarios, such as performing system-level jobs. The next example shows the sleep command in action from within a shell script. The wait command is used for pausing system processes from Linux bash scripts. Check out the following example for a detailed understanding of how this works in bash.

Sometimes you might need to find the last updated file for certain operations. The following simple program shows us how to do this in bash using the awk command. It will list either the last updated or created file in your current working directory. Instead, you can simply copy this code to get the task done. The below example will apply a custom extension to all of the files inside a directory.

Create a new directory and put some files in there for demonstration purposes. My folder has a total of five files, each named test followed by
