I'd like to extract the 2nd field and transpose it to become a row
cat > temp1
1 73
2 74
3 75
My approach :
cut -f2 temp1 | tr '\n' '\t' > temp2
The result :
temp2
73 74 75
Understandably, there is a tab separator at the right end of the line but missing a new line character. Is there an simple one-liner to fix this?
Use paste instead of tr:
$ cut -f2 temp1 | paste -s
73 74 75
verifying the invisible whitespace
$ cut -f2 temp1 | paste -s | od -c
0000000 7 3 \t 7 4 \t 7 5 \n
0000011
