Create custom commands in Linux (aka alias)

Let’s say you are using some of the commands frequently and you don’t want to type the whole command everytime. An alternative is to create a short command for it and use that instead.
First, go to the home folder in the terminal which looks like the following
/home/username
In case if you are in some other directory, you can type ~ in terminal and press Enter to get there
Next, you can list the contents of that directory including the hidden files using
ls -a
Here, -a is to show hidden files which start with dot
Among the list of files, find .bashrc and open it
At the end of the file, add some custom commands by using alias.
alias [custom command name]=’[original command]
Here is an example. You can create any number of custom commands here
After entering the custom commands, close the terminal and open a new one.

So, these fields will be added to the fields flowing in your current stream Currently, for the Pentaho 5.0, we are having a bug for ERROR_COUNT field, which is getting type as Long instead of Integer for some of the rows. So, as a temporary fix, we have used javascript to handle this public boolean processRow(StepMetaInterface smi, StepDataIn...

Copy files from one computer to other using ‘scp’ command

Image
copy files between computers using scp cmd scp file.txt remote_username@10.10.0.2:/remote/directory From the computer which has the source file, go to the command line and, provide the path of the source file followed by scp and then, username@hostname of the remote computer and then, the path where you want it to be copied on remote computer. Another example: Default port number is 22. So we generally use -P in case we have to explicitly specify any port other than 22 like below scp -P 2000 Downloads/simple2.html pi@raspberrypi.local:~/learning/python/webscraping Copy local directory to remote computer scp -r localDirectory user@remotecomp:/path-to-destination Working example: scp -r capturing-images pi@raspberrypi.local:/home/pi/Downloads Copy from Pi to your Mac scp user@remote:path-to-file .
