the condition to cut the content is
1. cut the content from the column 10 of each line
2. each line must be ended with a word that begins with bbb , so cut the content until bbb
3. erase all space ( -------- ) , then get the below result

Re: Cut column
awk '{print $2}' |head -1
the above script is simple , but in my case , the words "testing1" is only example , in real case , it is a string that have space in it ( not just a word ) , so if I want to cut the culumn from column 2 to second last 2 column , what can i do ? thx

Solution> Sorry , I have an adjustment, [...]
> [...] in real case [...]
Come back when you know what you want?
I'm not sure that the problem is well
specified, but something like the following
might be close to what you seek.
bash$ echo 'aaaaaa test ing 1 bbbb' | \
> sed -e 's/^.......... *//' -e 's/ *bbb[^ ]*$//'
test ing 1
The idea was to remove the first ten
characters ("^..........") plus any string
of spaces (" *"), and then to remove the
spaces leading up to "bbb" (" *bbb") and any
non-space characters between it and the end
of the line ("[^ ]*$").
(As I always say, "If you can't so it with
'sed', it's not worth doing.")
If you want only one line, "man head".

Re: Cut column
I would like to carify my requirement as below .
the file content
==========
aaaaaa ------------------ testing1 ----------------- bbbb
step 1
====
check if the line contain the word "test" , if not , then output the result "Do nothing" .
if have , then do step 2 .
step 2
====
cut the column from column 10 to last 10 column
so the result is
--------------- testing1 ------------
step 3
====
erase all space that in front of and in rear of the string "testing1" .
so the result is
testing

Re: Cut column
Will do. You're not paying enough to get
me to chase your ever-changing requirements.
I've provided a "sed" example which does
much of what you want (even now). If you
can't find someone to write your script for
you, perhaps you should try to study that
example, and adapt it to your (latest) needs.

I don't see how it could be. As I showed
before, I don't get those spaces.
Now, if they were tabs and not spaces, that
could change things. Of course, I can't see
what's really in your file, and there's no
reason to believe that you know what's in
there, either, and my psychic powers are too
weak to tell me, so I don't see what more I
can do.
