Alias in Linux

Here a simple way to create a simple name to execute a repetitive command:

You can open you .cshrc
nedit ~/.cshrc

Type in this file the following:

alias copyNow 'cp /home/username/file.xml /home/username/MyDir'

Finally compile this file
source ~/.cshrc

From now on whenever you type in any terminal

copyNow

the file file.xml will be copied in MyDir.

Many possibilities here!!

Nedit, simple text file editor in Linux

If you find an alternative to vi (prehistoric) try nedit in Linux, it's the simplest way to edit your text file

How to find Strings in linux directory

To find some string in a directory you can find a String in this way:

ps aux | grep stringToFind

Example, you have a directory called Fruit, which contains all kind of files with fruits. You need to search the file/s containing the word "Apple"

you go to Fruit directory:
cd /home/username/Fruit

then you search for the word Apple in all subdirectory:
ps aux | grep Apple *
ps aux | grep Apple */*
ps aux | grep Apple */*/*
 
... and so on till you have this indication:

grep: No match.

This means that you don't have any more subdirectories to explore

Up to know I use this command because is the simplest one.

- Open a shell and type:
  ps aux | grep tomcat
