Can someone help me to figure out this? Thanks in advance!
CodePudding user response：
Assuming file2.txt has just one line as shown, how about a paste solution:
paste file1.txt <(yes $(<file2.txt) | head -n $(wc -l <file1.txt))
yes $(<file2.txt)repeats the line of file2.txt.$(wc -l <file1.txt)returns the line count of file1.txt.head -n $(wc -l <file1.txt)prints as many lines as file1.txt.
CodePudding user response：
paste expects two file of equal length. I'm guessing you basically want this common Awk two-liner:
awk 'BEGIN { FS=OFS="\t" } NR==FNR { a[ i] = $0; next }
{ print $0, a[(FNR-1) % i 1] }' file2.txt file1.txt
(I have assumed your files are tab-separated; it's not clear from your question.)
