Shell Programming and Scripting

A script is very nice, this was actually the next step for me :-)
I have written the script but i think nothing happens.... where does the script save the new file? is actually a new file created? sry for this stupid questions but i´m not very familiar with UNIX or LINUX....

Ok, i also tried the awk command again, but nothing happens. I believe that i´m misunderstanding something..... after applying the command, is the file changed or is na new file created at a different place with this changes?

The awk program and the bash script will not modify your original file. Both of them reads from your file and prints 2nd & last column on standard output. If you want the output in a file, then you have to redirect it to a new file name.

BTW are you able to see the desired output on your screen while running the awk program or bash script?

unfortunalety i don´t see any ouput. i tried do modify the awk command in the way that new outout file is generated but this file is empty. do you think it would be easier by using a linux os instead of mac os?

I just borrowed a friend's mac. The awk program works there.

I bet your data is subtly different than what you showed.

Are there spaces at the beginning of the lines? That'd do it.

i guess you are right...
i would upload the file but i don´t find a possibility to do it here.....

It's there, look for 'manage attachments'.

You could also look at the file yourself and see.

the text structure of the file is like this:

text
text (space) text....
number (space) number (space).....
text

you know what i mean?
