Bash all arguments print

The purpose of this tutorial is to show how to print all of the arguments submitted from the command line in a Bash script on Linux. There are several different methods for doing this, as you will see in the examples below.

In this tutorial you will learn:

Bash all arguments print

---

There are couple ways how to print bash arguments from a script. Try some scripts below to name just few.

1. In this first script example you just print all arguments:

   #!/bin/bash 
   echo $@
   

2. If you intend to do something with your arguments within a script you can try somethign simple as the following script:

   #!/bin/bash 
   for i; do 
      echo $i 
   done
   

3. Next we have some script which are doing the same as the previous bash script but employ different approach:

   #/bin/bash 
   for i in $*; do 
     echo $i 
   done
   

4. Let’s print all bash arguments using shift:

   #!/bin/bash 
    
   while (( "$#" )); do 
     echo $1 
     shift 
   done
   

5. Or we can do something obscure like this to print all bash arguments:

   #/bin/bash 
    
   # store arguments in a special array 
   args=("$@") 
   # get number of elements 
   ELEMENTS=${#args[@]} 
    
   # echo each element in array  
   # for loop 
   for (( i=0;i<$ELEMENTS;i++)); do 
       echo ${args[${i}]} 
   done
   

Closing Thoughts

In this tutorial, we saw several different ways to print all of the arguments passed to a Bash script on the command line. As with most things in Linux, there is always more than one way to accomplish a task. Feel free to use whichever method best suits your situation at hand.
