Linux: Merging multiple files, each on a new line

问题:

I am using cat *.txt to merge multiple txt files into one, but I need each file to be on a separate line.

What is the best way to merge files with each file appearing on a new line?

回答1:

just use awk

awk 'FNR==1{print ""}1' *.txt 

回答2:

If you have a paste that supports it,

paste --delimiter=\\n --serial *.txt 

does a really great job

回答3:

You can iterate through each file with a for loop:

for filename in *.txt; do     # each time through the loop, ${filename} will hold the name     # of the next *.txt file.  You can then arbitrarily process     # each file     cat "${filename}"     echo  # You can add redirection after the done (which ends the # for loop).  Any output within the for loop will be sent to # the redirection specified here done > output_file 

回答4:

for file in *.txt do   cat "$file"   echo done > newfile 

回答5:

I'm assuming you want a line break between files.

for file in *.txt do    cat "$file" >> result    echo >> result done
