a little bash help: cat multiple files together except first line?

sanimfj · 02-09-2010, 01:10 PM

Hopefully the title summarized what I need help with. I have multiple files that I would like to concatenate in bash.

ie:

cat file1 file2 file3 > bigfile

except I do not want to include the first line from each file (). Any help? Thanks.

We'll be glad to help...post what you've written and tried so far. If you need a hint, I'd start by running the individual files through sed, and stripping the first line off there. A simple bash loop can go through all the files in a directory, strip the line, and add it to the output file.

Code:

cat <(tail +2 file1) <(tail +2 file2) <(tail +2 file3) > bigfile

Not really the most efficient method, but it does get it done.

Code:

awk 'FNR > 1' file? > bigfile
