UNIX for Dummies Questions & Answers

Hi
I am new to Unix and need help. How do I use the $@ in my script to direct the executing of commands on various files.
Thanks

Your question needs some clarification.

$@ returns command line parameters. What exactly are you trying to do?

Sorry for my unclear query earlier
Recently, I read something about the variable $@ but do not really know how to use it. My problem is as follows:
I have written a script such as:

#!/bin/bash
awk ' {....
}'

I would like to execute this script on afew datafiles, with different names ( .txt). How can I use $@, so that it automatically execute the commands on all files, one after another?
Hope you can help! Thanks

cheers

You could use a for loop, e.g....

Code:

#!/usr/bin/bash
for i
do
   : some command using $i
done

...but if you are using awk, then you can just use...

Code:

#!/usr/bin/bash
awk '{
  ...
  }' $@

Hi
Thank you for your explanation.
If I were to use the awk version and end it with $@, how can I execute the command to a list of filenames (I have numereous files and have listed the names in a list.txt file)?

Like this...

Code:

#!/usr/bin/bash
awk '{
  ...
  }' $(<list.txt)

Hey..
I've used the above to make this: #!/usr/bin/bash
args 2,5 $(<file.list)
and it works but I'll like the results separated into different files or back into the used files.
e.g. use fileA | args 2,5 > fileB or fileA and then do this to 50 files.
Is there an easy way?
Thanks!
