Combining two very large files ignoring the first sentence

问题

I want to combine two giant file each few hundred megabyte into a single file while ignoring the first line.

I wanted to use awk as I thought it should be the most optimized way. the way I'm doing it only ignores the first line of second file. Any idea how to do make work or if there's a faster way to do it?

awk 'FNR!=NR && FNR==1 {next} 1' 'FNR!=NR && FNR==1 {next} 2' s_mep_{1,2}.out >> s_mep.out

回答1:

$ awk 'FNR>1' file{1,2} > file_12

回答2:

With sed

(sed '1d' file_1 ; sed '1d' file_2) > new_file

回答3:

Generalizing to arbitrarily many files ...

for f in ... ; do
  tail -n +2 "$f" >> well_chosen_filename
done
