And here is the list of the common options:-a List all items.-c Get count of items.-d Output directory.-e Expands items.-f To specify a file.-h To show help page.-i To ignore character case.-l To list a text.-n To say no for a question.-o To send output to a file or so.-q Keep silent don’t ask the user.-r To process something recursively.-s Stealth mode.-v Verbose mode.-x Specify executable.-y To say yes without prompting the user.If you work with Linux, many of these options may look familiar to you.it’s good to follow standards.These parameters are useful if you want to validate executing file name and do the processing based on the arguments.

for example let’s create & execute the test script with some parameters : Our first file just have a ls command and echo of exist status: #! on execution , it gives 0 as exist status: ./letters osmodule rpms testfile txt1 Exit status is : 0 Our Second file just have a misspelled ls command and echo of exist status: #!

These bash positional parameters can be assigned to a variable and values can be used for further processing.

These are special parameters and has specific meaning according to the number.

If two arguments are passed in command line then the argument values will be received in

, and . If you want to store data in database or any file or create a report on particular format based on command line arguments values then getopts function is the best option to do the task. So, you can easily use this function in your script to read formatted data from command line.

It will count the total number of arguments, print argument values with loop and without loop. Run the bash script with the filename as single argument value and run another command to check the total number of characters of that file. Create a bash file and add the following script to understand the use of getopts function.
