Hello,
It is not a fedora question, but I am sure that somebody can help me.
I do: my_sort files.asc > new_file.asc 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) ?
Thank.

Assuming you are using bash: gawk -f file.awk -v sampl=T <(my_sort files.asc)
That will work as long as gawk is just going to read the data straight through and not do any seeking.

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

my_sort files.asc | gawk -f file.awk -v sampl=T
That's a better option than mine if it works. I assumed that it was requiring a filename, but that could be a wrong assumption.
Hello,
gawk -f file.awk -v sampl=T <(my_sort files.asc) This works very well. Actually, the other suggestions do not work.

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 -
