UNIX for Dummies Questions & Answers

Dear every one,
I am working with the data of my lab program and I have to do many times by the same list of some commands (grep, then save to file, then use awk to delete odd lines, save to file, use awk to delete even lines, save to file...).
Is there any way to save a list of command which I usually work with and then run them in the current shell?
I tried using {} as written in this site

Thanks a lot.

Can you provide details regarding in what ways your group command does not work?

If possible post the group command that you attempted to run and errors if any.

It is really difficult to comment without knowing what exactly you did and what issues you faced.

Here is the error I got.
{ grep -v 'Ni' Md_Coordinates.xyz > test.txt grep 'H' test.txt>test1.txt awk 'NR%2==0' test1.txt>test2.txt; }
Ambiguous output redirect.

and I could not see the files test.txt, test1.txt...

While grouping commands in single line, each commands has to be separated by semi-colon to clearly define boundary:

Code:

{ grep -v 'Ni' Md_Coordinates.xyz > test.txt; grep 'H' test.txt > test1.txt; awk 'NR%2==0' test1.txt > test2.txt; }

thank you!
