I do:

and then
gawk -f file.awk -v sampl=T new_file.asc
to get what I want.

how can I do the same in a single command with a pipe (and not generating
the new_file.asc) ?

my_sort files.asc | gawk -f file.awk -v sampl=T

You need to tell gawk to read from the standard input instead of a file so try this:

my_sort files.asc | gawk -f file.awk -v sampl=T -
